Streaming reads faster, custom API bodies, and a connection test - #1084
Streaming reads faster, custom API bodies, and a connection test
Six related changes, each in its own commit, on top of master.
1. Custom API request body
5da7480 — Advanced → API Params gains an Extra Request Body (JSON) textarea.
Whatever object it parses to is merged into the request body of every OpenAI-compatible,
Azure OpenAI and Anthropic request, so parameters the UI does not expose (thinking, reasoning_effort, top_p, …) can be sent. The Anthropic path forces thinking: {type: "disabled"} for claude-sonnet-5, and the user body now wins over it.
Invalid JSON, or JSON that is not an object, is ignored — the settings field says so
inline rather than failing the request later. stream is stripped: every API response is
read as an SSE stream, so letting it be overridden only produces a broken conversation.
Config: new extraBody key, default ''. Localized for en / zh-hans / zh-hant.
2. Cut streaming render cost
050b6da — two independent fixes to the same problem. A streamed answer arrived as a
series of cumulative snapshots and each one re-rendered the whole answer.
Streamed chunks are coalesced so a burst renders once per frame instead of once per
chunk, and the newest text is always flushed before the answer is finalized. The
contract lives in answer-buffer.mjs, with tests.
Syntax auto-detection is limited to a common-language subset. detect: true compiles
every registered grammar the first time it runs; restricting the scan keeps
auto-detection and drops that first-use cost. Explicitly labelled blocks are unaffected.
Measured on a 394-character answer, 19 chunks of 20 characters:
First code block on a cold page: ~132 ms before, ~4 ms after.
A burst (chunks arriving faster than frames): 48.6 ms CPU over 19 renders before,
11.0 ms over 6 renders after.
A slow stream (60 ms per chunk): 48.6 ms before, 29.6 ms after.
3. React compat alias raised to 18
1e89280 — react/react-dom move from @preact/compat@^17.1.2 to ^18.3.2 so
packages declaring a React 18 peer range can be installed. The alias is a thin re-export
of preact/compat (its entry points are 44–86 bytes), so the runtime implementation is
still preact@10.22.1 — this changes the reported version, not the rendering. Every API
the extension uses is still exported: unmountComponentAtNode, render, createPortal, findDOMNode, flushSync, unstable_batchedUpdates, and the hooks.
4. Render replies with HyperMarkdown
0a500c9 — replaces react-markdown with @aeven-ai/hypermarkdown, which caches
settled code lines, table rows and list items and parses only the block that is still
changing. Together with (2), a long answer no longer re-parses from the top on every
update — that was the remaining quadratic term.
Integration notes:
Answers reach the renderer as deltas. stream-delta.mjs turns the cumulative snapshots
the providers emit into deltas and finalizes the stream once it ends; stored answers
render in one pass.
The custom <think> card is gone: reasoning blocks are native. They open while the
model is thinking and collapse with a duration when it stops.
Hyperlink is kept — it routes chatgpt.com / claude.ai / kimi links into an extension
tab with a jump-back notification. The renderer's own linkSafety only decides where
links may point.
The loading placeholder is injected as HTML and styled through .gpt-loading, so allowedTags: { p: ['className'] } keeps that class; it is stripped by default.
Sanitization otherwise keeps <sup> (Bing's citation markers) and <details>, and
drops onclick.
Fullscreen and the HTML preview are off for code blocks and tables: both expect the host
to hide its own chrome around them, which this card does not do.
Redundancy removed:
markdown-without-katex.jsx, a 200-line near-duplicate of the renderer. The KaTeX-free
build now swaps one module — math-plugin.mjs for math-plugin-without-katex.mjs —
through the NormalModuleReplacementPlugin hook that already existed for this purpose.
Verified: the minimal build still ships zero KaTeX.
Pre.jsx, the custom code-block wrapper, now that the renderer has its own toolbar. This drops the per-block font-size selector — the renderer has no equivalent.
change-children-font-size.mjs, orphaned by that removal.
Unused dependencies: react-markdown, remark-breaks, rehype-raw, github-markdown-css (never imported — its CSS was vendored into styles.scss), and parse5.
The parse5 webpack alias, which forced every parse5 import to the root v6 and broke hast-util-raw v9, which needs v7. Nothing in src imports parse5.
Known behavior changes:
Single newlines no longer become <br>.remark-breaks has no equivalent in the
new renderer and went with the rest of the react-markdown stack. Review wanted:
ChatGPT behaves the same way, but this is visible for anyone who relied on it.
Code blocks get the new renderer's toolbar (copy; fullscreen and preview are off) and
its own theme.
Bundle size for the full build grows ~6.7% (chromium: 5,496 KB → 5,865 KB across all
emitted JS/CSS) — the renderer and its unified@11 stack, minus the react-markdown
stack they replace.
5. Connection test for API modes
eaf7c67 — every row under Modules → API Modes gets a Test action that sends a
one-token chat request and reports reachable plus latency, or the provider's own error.
It resolves the endpoint, key and model through resolveOpenAICompatibleRequest — the
same helper the real request path uses — so a mode that passes here is a mode that can be
talked to. Token parameters go through getChatCompletionsTokenParams, so a gpt-5
family mode is probed with max_completion_tokens instead of failing on the wrong key.
Timeouts and transport failures are reported as data, never thrown. Requested in #916.
6. Show reasoning content
0c0f3fa — reasoning models put their thinking in delta.reasoning_content (DeepSeek R1)
or delta.reasoning (OpenRouter-style) rather than in the content. buildMessageAnswer()
read delta.content and nothing else, so that text was dropped entirely and the user saw
the answer appear as if out of nowhere.
The thinking is now streamed to the card on its own channel and rendered as a reasoning
block ahead of the answer — open while it arrives, collapsed with a duration once it
stops, and re-openable afterwards.
It is deliberately not merged into the answer. pushRecord() still stores only the
answer text, so thinking never re-enters the conversation context on the next turn, which
is what DeepSeek does with reasoning_content too. Both halves of that — thinking is
shown, thinking is not sent back — are asserted in tests/unit/services/apis/reasoning-content.test.mjs. Requested in #839.
Why these changes: what the issue tracker says
Searched the upstream tracker for the needs behind this branch.
自定义api栏目能自己增加备注么，以及模型测活功能 #916 (open) — notes on custom API entries and a model liveness check. Covered by
(5); the notes half is not implemented.
希望增加reasoning_content的输出支持 #839 (open, 11 reactions) — surface reasoning_content from DeepSeek R1 without
sending it back in context. Covered by (6). Highest-signal request found; (1) is the
other half of it, letting a request ask for thinking in the first place.
Reconcile the stylesheets.src/content-script/styles.scss vendors a github-markdown-css copy scoped to .markdown-body, while the renderer styles .hypermarkdown inside it. The two overlap on code blocks, tables and headings. The
legacy block should shrink, but that needs visual QA, not a blind deletion.
Localize the renderer's toolbar strings (copy, fullScreen, preview, …). Only
the reasoning headers are wired to i18n so far.
Claude's thinking_delta is still ignored by the Anthropic path, so API-based
Claude thinking does not reach the UI yet. Same shape of change as (6).
Validation
npm test — 1089 passing, 12 of them new (extra-body-params, extra-body-request, answer-buffer, highlight-options, stream-delta, test-connection).
npm run lint and Prettier — clean.
npm run build — all four variants build; build/chromium/ contains manifest.json, background.js, content-script.js, content-script.css, popup.*, IndependentPanel.*, rules.json and logo.png.
npm ci installs cleanly from the committed lockfile; the resolved tree dedupes to a
single @preact/compat and a single preact.
The KaTeX-free variant emits no KaTeX in either JS or CSS.
The outgoing request body is asserted for each of the three request builders with a
stubbed fetch, and the streaming buffer is checked against a fake frame clock.
Not done: manual browser testing. No browser automation was available here. Before
merging, load build/chromium/ and check a streamed answer containing a code block and a
table, a <think> block, an error message (the gpt-loading class), a Bing answer with <sup> citations, a non-English locale, and the new Test button against both a working
and a broken endpoint.
Summary by CodeRabbit
New Features
Added an “Extra Request Body (JSON)” setting for customizing API requests, with validation guidance.
Added connection tests for supported providers and custom models, showing reachability and response time.
Added separate display of streamed reasoning and response content.
Updated Markdown rendering with syntax highlighting and math support where available.
Bug Fixes
Made streamed response updates smoother and improved handling of interrupted responses.
Improved list markers and reasoning behavior across retries and completed responses.
Localization
Added English and Chinese translations for the new settings, validation messages, and connection-test statuses.
Expose a JSON textarea under Advanced > API Params that merges user-provided fields into the OpenAI-compatible, Azure OpenAI and Anthropic request bodies, so parameters the extension does not surface (thinking, reasoning_effort) can be sent.
The stream key stays under extension control to keep SSE replies intact.
Coalesce streamed answer chunks into one render per frame instead of re-rendering the whole answer on every chunk, and limit syntax auto-detection to common languages so the first code block no longer compiles every registered grammar.
Measured: cold first code block ~132ms -> ~4ms; a bursty stream uses ~4.4x less render CPU.
Point react and react-dom at @preact/compat 18.3.2 so dependencies that declare a React 18 peer range can be installed. The alias is a thin re-export of preact/compat, so the runtime implementation is unchanged.
Replace react-markdown with HyperMarkdown, which parses only the blocks that are still changing and caches the ones already settled, so a long answer is no longer re-parsed from the top on every frame. Answers are handed over as deltas and finalized when the stream ends.
Remove what the swap made redundant: the KaTeX-less renderer copy (now a plugin swap driven by the existing build hook), the custom code-block wrapper, an orphaned font-size helper, a vendored stylesheet dependency that was never imported, and the react-markdown dependency stack.
Each API mode row gets a Test action that sends a one-token chat request through the same provider resolution the real request path uses, and reports reachability, latency, or the provider's own error. Requested in ChatGPTBox-dev#916.
Reasoning models put their thinking in delta.reasoning_content (DeepSeek R1) or delta.reasoning rather than in the content, and it was being dropped. Stream it to the card on its own channel and render it as a reasoning block ahead of the answer.
The thinking is deliberately kept out of session.conversationRecords, so it never re-enters the context on the next turn - which is what DeepSeek does with reasoning_content too. Requested in ChatGPTBox-dev#839.
The custom model is configured on the General tab, not as an API mode row, so 5e0edf1 style row action never reached it. Generalise the background entry point to take a session-shaped selector and reuse it in both places.

📝 Walkthrough
Walkthrough
The pull request replaces the Markdown renderer, adds buffered answer streaming and separate reasoning display, supports extra JSON request fields across providers, and adds API endpoint connection tests.
The renderer now uses HyperMarkdown. The changes add streaming support, reasoning-tag handling, highlighting options, list-marker normalization, and KaTeX-free build substitutions. They also remove the previous renderer and code-block font-size utility.
Conversation cards buffer answer updates and store reasoning separately. OpenAI-compatible streams separate reasoning from answer content and record only the resolved answer.
API request and connectivity changes
Layer / File(s)
Summary
Extra request fields across providers src/config/index.mjs, src/popup/sections/AdvancedPart.jsx, src/services/apis/*, src/_locales/*, tests/unit/services/*
The API settings add a JSON request-body field. Valid object fields are merged into provider requests, while the stream field remains controlled by the extension.
API mode rows and the custom model setting can send connection tests. The background service runs provider-specific probes and returns connection results and elapsed time.
The streaming and connection-test changes address the identified retry, incomplete-reasoning, provider-probe, and keyboard-use concerns. No actionable merge-blocking risk remains in the reviewed changes.
Security Architecture Review
Security architecture risk:🔵 Low · up to aede3
The inspected paths preserve streaming control, separate request bodies from credentials, and prevent connection tests from following redirects. No introduced security vulnerability was established. Some important checks remain incomplete, particularly the new renderer’s sanitization behavior and the full caller-to-destination controls for connection tests.
Retained concerns
No architecture-level concerns identified.
Security review details
Security Blast Radius
inferred — The material security scope is the extension’s provider credentials, outgoing API requests, conversation records, and DOM rendering of provider-supplied content. The new connection-test path can exercise supported API provider families using stored configuration; its complete legacy custom-destination binding remains unresolved.
Trust Boundaries and Controls
observed — The inspected extra-body producer is the extension settings textarea. In the core request path, its fields are serialized into the POST body; requestUrl and credential-bearing headers are supplied independently. Broad body-field precedence alone does not establish an attacker-controlled endpoint or credential transition.
observed — Connection tests reject unsupported provider groups, force stream to false after extra-body merging, and use manual redirect handling. An opaque redirect is reported as failure instead of being followed to another credential destination.
Resilience and Maintainability Implications
observed — Each connection probe has a 20-second abort timeout and clears its timer in finally. This bounds request duration, but is not a fixed token-budget guarantee: configured extra-body fields can replace token limits, and Anthropic thinking configuration can increase the probe’s generated limit.
Hardening Proposals
proposed — Establish the new renderer’s effective HTML, attribute, and URL policy across incremental writes and both build variants. Verify sanitizer ordering and custom-link inputs explicitly rather than treating the sanitizer dependency declaration as proof of enforcement.
proposed — Make connection-test caller authority and credential-to-destination binding explicit, including legacy custom-URL recovery. If testing is intended to be settings-only, enforce that restriction at background dispatch rather than relying solely on the popup caller.

High-Level Assessment
The following are alternative approaches to this PR:
1. Incrementally optimize ReactMarkdown
➕ Retains the mature existing renderer and current output semantics.
➕ Avoids a new React 18 peer dependency and renderer-specific integration layer.
➖ ReactMarkdown accepts complete documents, making settled-block caching difficult.
➖ Would require substantial custom parsing, memoization, and stream-boundary logic.
➖ Retains more locally maintained code for thinking, code controls, and minimal builds.
Recommendation: The HyperMarkdown approach best addresses repeated full-document parsing and consolidates streaming controls, reasoning, code, and math behavior. Centralizing extra-body parsing and reusing provider resolution for connection tests are also appropriate. Review should prioritize Markdown output compatibility, sanitization, Preact compatibility, and minimal-build behavior because the renderer migration introduces the greatest dependency and regression risk.

1. Completion model tests report false failures✓ Resolved
Description
testConnection unconditionally sends chat-completions fields (messages) even when
resolveOpenAICompatibleRequest resolves a completion endpoint. Modes in gptApiModelKeys use
/completions and a prompt during normal generation, so an otherwise working completion endpoint
can reject this test body.
The provider registry explicitly designates gptApiModelKeys as completion endpoints and resolves
their completion URL, while the production completion path builds a prompt body. The newly added
test always constructs a messages body.
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution
Issue description
The connection test always creates a chat-completions body, including `messages`, even for modes resolved to a completion endpoint. Completion endpoints require the prompt-based request shape used by normal generation.
Fix Focus Areas
- src/services/apis/test-connection.mjs[35-40]
- src/services/apis/openai-compatible-core.mjs[91-105]
Recommended Fix
Branch on the resolved endpoint type. For completion endpoints, send a minimal `prompt` request with the correct token parameter and `stream: false`; preserve the existing messages request for chat endpoints.

2. Azure and Anthropic tests always fail✓ Resolved
Description
runConnectionTest exposes the Test action for every API-mode row, while testConnection only
calls resolveOpenAICompatibleRequest, which has no provider mapping for the Azure and Anthropic
groups. Selecting either native API mode returns unresolved-provider without contacting its
configured endpoint, even though normal generation dispatches them through dedicated protocols,
including Azure's deployment-specific URL and api-key authentication.
The UI renders Test unconditionally for every API-mode row, including the configured Azure and
Anthropic groups. Neither group appears in the OpenAI-compatible provider mapping, so resolution
returns null, while their production generation paths dispatch separately through native request
implementations; Azure specifically uses a deployment-specific URL and an api-key header.
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution
## Issue description
The Test action is rendered for Azure and Anthropic API modes, but the handler only resolves OpenAI-compatible requests. Valid configurations for these native providers are therefore reported as unreachable without contacting their configured endpoints.
## Fix Focus Areas

- src/services/apis/test-connection.mjs[17-47]
- src/services/apis/azure-openai-api.mjs[28-47]
## Recommended Fix
Dispatch connection tests according to the selected provider family. Add Azure and Anthropic request builders that reuse the endpoint and model resolution, request body shape, and authentication headers from their production generation paths; for Azure, use the deployment-specific URL and `api-key` header. If a mode cannot be tested safely or has no supported implementation, hide the Test action or explicitly mark it unsupported.

7. Answers mentioning a loading class disappear 🐞 Bug≡ Correctness⭐ New
Description
buildStreamedContent treats any answer containing the substring gpt-loading as the waiting
placeholder and replaces the entire answer with an empty string. When reasoning is present and a
genuine reply mentions that class in prose or code, the renderer shows the reasoning block but drops
the reply.
+ const answer = children.includes(ANSWER_PLACEHOLDER_CLASS) ? '' : children
Evidence
The card passes answer text and reasoning to the renderer and uses a specific HTML element as its
waiting placeholder. The helper instead checks children.includes('gpt-loading') against the whole
answer, so it discards text that merely mentions the class rather than matching the placeholder
markup.
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution
## Issue description
A genuine answer that mentions `gpt-loading` is discarded whenever reasoning is present because the placeholder check searches the entire answer for that substring.
## Fix Focus Areas
- src/components/MarkdownRender/reasoning-content.mjs[18-24]
- src/components/ConversationCard/index.jsx[523-529]
## Recommended Fix
Distinguish the card's actual waiting placeholder from arbitrary answer text. Match the complete placeholder markup, for example with an anchored check such as `/^<p class="gpt-loading">[\s\S]*<\/p>$/.test(children)`, or pass an explicit placeholder flag from the card. Add a test with reasoning and an answer that mentions `gpt-loading`.

8. Changed settings retain an old test result 🐞 Bug≡ Correctness⭐ New
Description
getConnectionTestKey omits credentials and the configured URL behind a provider ID, while the
General tab also retains its connection-test result when custom-model settings change. Editing those
settings after a probe—or while one is pending—can leave a Reachable result displayed for
credentials or an endpoint that was never tested.
The mode result key contains only row identity fields, although the background probe reads current
configuration to construct its request. Both test controls retain their result state while editable
settings change.
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution
## Issue description
Connection-test results remain visible after their request settings change, and pending results can update the changed configuration's status.

- src/popup/sections/ApiModes.jsx[293-310]
- src/popup/sections/GeneralPart.jsx[110-123]
## Recommended Fix

9. Some code examples lose literal tags 🐞 Bug≡ Correctness⭐ New
Description
escapeTagsOutsideCode treats any backtick or tilde fence as closing the current fence, without
matching its delimiter or length. In a four-backtick code block containing a three-backtick line, it
escapes tags inside the code and leaves tags in subsequent prose unescaped, where the renderer can
consume them as markup.
+ const isFenceLine = FENCE_PATTERN.test(line)+ if (inFence) {+ if (isFenceLine) inFence = false+ return line
Evidence
The fence pattern accepts either delimiter with three or more characters, and the state machine uses
that same boolean to close any open fence. The helper's own contract requires code tags to remain
untouched and prose tags to be escaped before rendering.
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution
## Issue description
The reasoning-tag escaper loses track of code blocks when a line uses a different or shorter fence delimiter.
## Fix Focus Areas
- src/components/MarkdownRender/special-tags.mjs[2-2]
- src/components/MarkdownRender/special-tags.mjs[31-45]

10. Replies opening with an unclosed tag stay hidden 🐞 Bug≡ Correctness⭐ New
Description
While streaming, resolveStreamText treats an unclosed leading <think>-style block as reasoning
with answer '', so no answer is ever posted. finish() records the full text as the answer but
deliberately does not post it, so the card's content stays the gpt-loading placeholder: the reply
appears only inside the thinking block, and Copy and Read return placeholder HTML until the page
reloads.

Evidence
splitInlineReasoning returns answer '' for an unclosed block, and postStreamText posts only
differing answers. finish() pushes the full answer to the record but posts only {answer:null,
done:true}. buildStreamedContent then treats the placeholder content as an empty answer, and
ConversationItem's Copy/Read use content, which is still the placeholder.
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution
## Issue description
A response beginning with an unclosed <think>-style tag is recorded as the answer but never sent to the card, so the card keeps the loading placeholder and shows the text only as thinking.
## Fix Focus Areas
- src/services/apis/openai-compatible-core.mjs[141-172]
- src/components/ConversationCard/index.jsx[262-266]
## Recommended Fix
In `finish()` (and the abort path), when `splitInlineReasoning(answer).unclosed` is true, post `{answer, reasoning: '', done: false}` before the done message. Update the card so an explicitly empty `reasoning` string clears the item's reasoning (check `'reasoning' in msg` instead of truthiness).

11. Stale partial text stays shown during thinking 🐞 Bug≡ Correctness⭐ New
Description
postStreamText posts answer: '' when earlier text turns out to be the start of a <think>
block, but the card only applies answers through if (msg.answer), so the empty string is dropped.
A first chunk such as <th therefore stays displayed and in partialAnswerRef, and
buildStreamedContent sees a non-empty answer and collapses the thinking block and stops its timer
while thinking is still streaming.
The core posts the resolved answer whenever it differs from the last one posted, including ''. The
card ignores falsy answers, and reasoning-content treats any non-placeholder answer as the answer
having started.
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution
## Issue description
An empty answer posted after the prefix becomes a thinking tag is ignored by the card, leaving stale fragment text and collapsing reasoning early.
## Fix Focus Areas

- src/services/apis/openai-compatible-core.mjs[151-161]
## Recommended Fix
In portMessageListener use `typeof msg.answer === 'string'` so '' replaces the content and partialAnswerRef. Alternatively, hold back posting a leading fragment that could still become a reasoning tag.

17. Retries show the previous reasoning✓ Resolved
Description
updateAnswer preserves copy[index].reasoning whenever it replaces answer content, including the
loading replacement created by getRetryFn, while reasoning updates only occur for truthy incoming
values. When a retry or error replacement emits no reasoning, the superseded thought survives
through the loading state and final answer, reaches MarkdownRender, and is prepended to the
unrelated content.
The cited updateAnswer implementation copies the existing answer item's reasoning during
replacement, while the retry path resets only the content by passing a loading placeholder. The item
renderer then forwards the preserved reasoning to MarkdownRender, which prepends every nonempty
reasoning value as a think block; because the message listener does not send an empty reasoning
update for models that produce none, the stale value is never cleared.
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution
## Issue description

Add provider-specific connection-test requests.
resolveOpenAICompatibleRequest cannot provide Azure OpenAI or Anthropic request semantics. The current request always sends Bearer authentication and an OpenAI-compatible body. Azure OpenAI and Anthropic modes will therefore report an unsuccessful connection even when their configured endpoint, key, and model work.
Dispatch to the provider-specific request builder, or normalize each provider into a connection-test request with its required URL, headers, and body. Add Azure OpenAI and Anthropic test cases.
Based on PR objectives: “Each API mode receives a connection test reporting reachability, latency, or provider errors.”

Review details
Suppressed comments (4)
src/components/MarkdownRender/markdown.jsx:50
Thought for {seconds}s is not present in the locale files (only Thinking Content is), so i18next falls back to this English key and the reasoning duration header remains English in non-English locales. Add this key to the supported locale files or use an existing localized string.
This resolver only handles the OpenAI-compatible provider registry, but the new Test action is rendered for every API-mode row. Claude, Azure, and web modes have no entry in OPENAI_COMPATIBLE_GROUP_TO_PROVIDER_ID, so clicking Test for those rows always returns unresolved-provider instead of testing the configured mode. Restrict the action to supported rows or add provider-specific test requests.
The real request path derives a request-shaping provider ID before calling getChatCompletionsTokenParams, including mapping an OpenAI-lineage provider using the native OpenAI URL to openai. Passing the raw request.providerId here makes a custom provider targeting OpenAI probe a gpt-5 model with max_tokens while real requests use max_completion_tokens, so the new test can fail for a working mode.
The production OpenAI-compatible path rejects native Ollama /api/chat endpoints before sending a request, but this probe posts its OpenAI body to every URL returned by the resolver and treats any 2xx response as success. A native Ollama mode can therefore show Reachable even though the real conversation path will always throw; mirror the same endpoint guard or exclude unsupported native endpoints.

Important
One build-output regression: the -without-katex-and-tiktoken artifacts emit a shared.css chunk that is never packaged, so the new HyperMarkdown/tippy styles are missing from those builds even though their JS still renders through them. A few smaller findings are inline.
Reviewed changes
Custom request body — new extraBody config, JSON-parsed and merged last into the OpenAI-compatible, Azure and Claude request bodies; stream is stripped and parseExtraBody rejects non-objects. UI textarea lives in Advanced → API Params.
Streaming render cost — answer-buffer.mjs coalesces cumulative answer snapshots to one render per frame with a flush before finalize; highlight-options.mjs narrows rehype-highlight auto-detection to a language subset.
React compat alias 18 — react/react-dom now alias @preact/compat@^18.3.2 (runtime implementation is still preact).
HyperMarkdown renderer — markdown.jsx rewritten over @aeven-ai/hypermarkdown with stream-delta.mjs; removes react-markdown, Pre.jsx, markdown-without-katex.jsx, change-children-font-size.mjs and the parse5 alias; build.mjs now swaps math-plugin.mjs instead of markdown.jsx.
Connection test — new TEST_API_CONNECTION background message resolves through resolveOpenAICompatibleRequest and posts a one-token probe; Test buttons in ApiModes.jsx (per row) and GeneralPart.jsx (custom model).
Reasoning content — delta.reasoning_content/delta.reasoning streamed on a separate channel and rendered as a native reasoning block, deliberately kept out of stored records.
Verification performed this run: npm test (1093 pass / 0 fail), eslint and prettier on the changed files (clean), and a clean npm run build after clearing the webpack cache.
ℹ️ Nitpicks
The committed package-lock.json no longer matches package.json under npm 11: less's optional dependency entries (errno, make-dir, mime, needle, probe-image-size, prr, iconv-lite, safer-buffer, stream-parser, debug, ms) were pruned, and npm ci exits 1 with Missing: … from lock file. CI pins Node 22 (npm 10) and still passes, so this is not blocking today, but it contradicts the "npm ci installs cleanly from the committed lockfile" claim and will break any contributor or job on Node 24/npm 11. Regenerating the lockfile without --omit=optional fixes it.
Thinking Content and the new Thought for {seconds}s are absent from src/_locales/en/main.json, the source-of-truth locale. t('Thought for {seconds}s') only survives because i18next returns the key as a template string; the repo convention is to add new source strings to en/main.json first.
Thanks for the substantial contribution here. Overall, I think this PR brings meaningful improvements to ChatGPTBox, particularly around streaming/rendering performance, reasoning support, custom request parameters, and API connectivity testing.
Before we move toward merging, could you please review and follow up on the remaining comments where appropriate? I’d prioritize the connection-test request semantics, reasoning lifecycle, and the no-KaTeX build styling issue.
Some automated comments don’t appear to require changes, so feel free to skip those with a brief note.
After the fixes, a final test/build run and a small manual browser smoke test would be appreciated.
Connection tests build the same request as the live OpenAI-compatible path
now: the configured extra request body is merged, token limits follow the
resolved provider, completion modes send a prompt, and Azure and Anthropic
are probed through their own endpoints and authentication. Results are shown
on the Test button itself, which keeps the row layout stable.
Reasoning is handled end to end. Retries and error replacements no longer
carry a stale thought, the thinking block streams expanded and collapses with
its real elapsed time, and `<think>`-style tags are split out of the answer
into the reasoning channel (or shown literally for user input and for tags
mentioned in prose or code) instead of being swallowed.
Markdown lists are numbered by the browser, so bullets nested in a numbered
list stay bullets and a list that resumes at another number no longer
restarts at 1. The minimal builds ship the renderer stylesheet without the
KaTeX assets, and the new reasoning strings are localized.
Adds unit coverage for connection request shaping, inline reasoning, the
reasoning wrapper, list start normalisation and special tag escaping.
Resolves the ConversationCard conflict between the transport disposal work
(ChatGPTBox-dev#1083) and this branch's reasoning cleanup, keeping both: the card disposes
its own transports on unmount, and error replacements still clear the stale
reasoning.
Upstream's lifecycle tests render the card in jsdom, which has no animation
frames, so the answer buffer now falls back to a timer when the host does not
provide one.
@PeterDaveHello thanks for the detailed pass. Here is the follow-up on the three areas you prioritised, the automated comments we skipped, and the test/build plus browser smoke test you asked for. Everything is in f833e3e, on top of a merge of current master (c4cf0ae), so the branch applies cleanly.
1. Connection-test request semantics
Probes build the same request as the live OpenAI-compatible path now: the configured extra request body is merged in (with stream: false forced afterwards), token limits come from the resolved provider instead of the raw id (max_completion_tokens for OpenAI-lineage GPT-5 models), and completion modes (gptApiModelKeys) send prompt + max_tokens instead of messages.
Azure (deployment URL + api-key header) and Anthropic (/v1/messages + x-api-key / anthropic-version, with thinking disabled where the live path disables it) are probed through their own protocols instead of coming back as unresolved-provider.
The Test action only renders for modes we can actually probe, so cookie/web rows and the third-party relay no longer show a misleading red "Unreachable". Results are keyed by stable mode identity rather than row index, and the outcome is shown on the button itself (label, colour, tooltip) so the row layout stays stable.
2. Reasoning lifecycle
Retries, model switches and error replacements clear the previous thinking, and buffered answer frames are discarded when the card is cleared, unmounted, or a new question starts.
The thinking block streams expanded and collapses with its real elapsed time; it previously collapsed immediately and read "Thought for 0s".
Reasoning-only chunks no longer repost an unchanged answer.
<think>-style tags are handled explicitly: a leading block a provider streams inside the answer is moved to the reasoning channel, so it stays out of the saved answer and the request context, while tags the user typed — or that appear in prose or code — are rendered literally instead of being swallowed.
3. no-KaTeX build styling
Root cause: the -without-katex-and-tiktoken variant keeps the components tree in the shared entry, so the renderer stylesheets landed in shared.css, which finishOutput never copies — those artifacts shipped the renderer JS with no styling at all.
Fix: the renderer stylesheets are imported by the content-script entry, so they land in the shipped content-script.css in every variant, and the minimal build swaps mykatex.min.css for an empty stylesheet so no KaTeX selectors or fonts are packaged.
Measured: the minimal content-script.css went from 0 to 301 .hypermarkdown rules with 0 KaTeX font faces; the full build is unchanged byte-for-byte and the minimal zip grows by about 5 KB.
Automated comments we skipped
Double-quoted JSX attributes, over-length test imports and long locale lines: Prettier's configuration decides these, and every touched file passes prettier --check (running npm run pretty would revert the change).
Ten locales without the new keys: en is the documented source of truth and the other locales fall back to it, so only zh-hans and zh-hant were translated.
Test/build run and manual smoke test
npm test: 1159 pass, 0 fail (including the lifecycle tests that arrived with master).
npm run lint and prettier --check: clean.
npm run build: all four variants; manifest.json, background.js, content-script.js, content-script.css, popup.html/js, IndependentPanel.html/js, shared.js, logo.png and rules.json present, with the minimal CSS free of KaTeX.
Manual smoke test: the real build loaded as an unpacked extension in a throwaway browser profile and driven against a mock OpenAI-compatible SSE endpoint (no user profile touched). The content script and popup ran without errors; the probe sent {model, messages:[ping], max_tokens:1, reasoning_effort:"high", stream:false}; an answer rendered 1. / 2. with nested bullets and then resumed at 3.; the thinking block expanded while streaming and settled on "Thought for 4s".
Worth flagging as well: the branch was 13 commits behind master and conflicted with #1083 in ConversationCard, so this pass merges master and keeps both behaviours — the card still disposes its own transports on unmount, and error replacements still clear stale reasoning. Upstream's new lifecycle tests render the card in jsdom, which has no animation frames, so the answer buffer now falls back to a timer when the host does not provide one.
I also mannually tested this plugin on chrome, everything works fine.

Connection probe reworked — buildOpenAICompatibleTestRequest now sends the completion prompt shape when endpointType === 'completion', derives token params through resolveProviderRequestShapingId, and Azure/Anthropic get dedicated request builders. The Test control is gated on canTestConnectionSession, results are keyed by mode identity instead of row index, and the control is a real <button>.
Inline reasoning split off — splitInlineReasoning removes a leading <think>-style block from the answer, streams it on the reasoning channel, and keeps it out of stored records.
Reasoning rendering — escapeReasoningTags, buildStreamedContent, and normalizeListStarts show reasoning tags as literal text, collapse the block only once thinking has stopped, and clean the streaming-only start="0" list attribute. New unit tests cover each.
Minimal-build CSS fix — the renderer stylesheets moved from markdown.jsx to the content-script entry (which IndependentPanel also loads), and the KaTeX-free build swaps mykatex.min.css for an empty file.
Retry clears reasoning — updateAnswer accepts an explicit reasoning value and the retry/error paths pass ''.
Locale strings — Thinking Content and Thought for {seconds}s added to the source-of-truth en/main.json, plus zh-hans/zh-hant.
Verification this run: the affected and adjacent suites (tests/unit/services/apis/*, tests/unit/components/*, tests/unit/popup/*) pass, 375/0.
Store thrown errors as their message: the renderer only takes text, so a
failed retry or submit used to hand an Error object to the delta helper and
break the answer card instead of showing what went wrong.
Disable the Test buttons while a probe is running, so repeat clicks cannot
race and let an older result overwrite a newer one.
Make the probe refuse redirects: following one would send the configured
credentials elsewhere and report success for whatever answered instead. Also
mirror the live path's refusal of Ollama's native /api/chat endpoint, which
the probe would otherwise report as reachable.
Keep the answer when a `<think>` block never closes. A response truncated
during thinking, or a reply that merely starts with the tag, is now recorded
as the answer once the stream ends instead of being dropped.
Follow-up on the second review pass — all actionable findings are addressed in a4c5d4c.
Thrown errors break the answer card (ConversationCard/index.jsx): the renderer only takes text, and the delta helper calls content.startsWith, so an Error object used to break the bubble instead of showing the failure. Both catch paths now store e?.message ?? String(e).
Concurrent probes (ApiModes.jsx, GeneralPart.jsx): the Test buttons are disabled while a probe is pending, and both handlers return early on a repeat click, so an older response can no longer overwrite a newer result.
Redirects on credentialed probes (test-connection.mjs): the probe now uses redirect: 'manual' and reports a redirect as a failure instead of following it and answering for whatever host it points at.
Unclosed <think> block (inline-reasoning.mjs, openai-compatible-core.mjs): an unclosed block is only treated as thinking while the stream is still running. Once it ends — token limit during thinking, or a reply that literally starts with the tag — the text is kept as the answer, so the response is no longer lost from the conversation record.
Ollama native endpoint (test-connection.mjs): the probe now mirrors the live path's refusal of /api/chat, so a custom provider pointed there reports unsupported-provider instead of Reachable.
Not applicable (checked, no change needed): Copilot's note on content-script/index.jsx — src/pages/IndependentPanel/index.html links content-script.css and loads content-script.js, so the standalone conversation page already receives the stylesheet the renderer styles live in. The Test-style gate the comment relies on does not apply because the panel is not a separate bundle.
Validation on a4c5d4c: npm test 1162 pass / 0 fail (new cases cover the Ollama guard, the redirect response and the unclosed tag), npm run lint and prettier --check clean, npm run build all four variants.

Stored thrown errors as their message in the answer card — the retry/submit catches now pass e?.message ?? String(e) so a failed generation renders text instead of handing an Error to the renderer.
Gated the Test controls on an in-flight probe — repeat clicks early-return and the buttons disable while pending, so a stale result cannot overwrite a newer one.
Made the connection probe refuse redirects and native Ollama endpoints — redirect: 'manual' reports an opaqueredirect as unreachable, and hasNativeOllamaChatApiPath is now shared with the live path so an unusable /api/chat mode is no longer reported reachable.
Kept a truncated unclosed Thinking block as the answer — splitInlineReasoning returns unclosed, and finalization records the raw text instead of dropping it.
Prior feedback from the last review is addressed: the Ollama guard thread is resolved, and the second-pass findings (error strings, concurrent probes, redirect/liveness parity) are covered by this commit.

Finalising an unclosed thinking block restored its raw text as the answer,
but the card still held the same text as streamed reasoning, so the renderer
showed two thinking blocks for one truncated response.
Record the restored text without posting it as an answer: the card already
shows it in its thinking block, which keeps collapsing with the elapsed time.
Both findings from the newest pass are the same issue, and it is fixed in aede3f3.
The unclosed-<think> fallback only changed what gets recorded: the text was restored as the answer while the card still held the same text as streamed reasoning, so buildStreamedContent prepended its own block and the renderer drew the raw tag as a second one.
Resolution: finish() now records the restored text without posting it as an answer. The card keeps showing exactly what it streamed — one thinking block, which still collapses with its elapsed time — and the truncated text stays in the conversation record, so nothing is lost or displayed twice.
ConversationCard was left alone on purpose: no explicit empty-reasoning message is needed once the raw text is not sent to the answer channel, which keeps the port protocol unchanged.
Validation on aede3f3: npm test 1162 pass / 0 fail — the unclosed-block case now asserts the text is recorded, that it is not posted as an answer, and that the reasoning channel only carried it once — plus npm run lint, prettier --check and npm run build (all four variants).
This removes start="0" from every ordered list, including a user-authored Markdown list that intentionally starts at zero. The DOM no longer contains enough information to distinguish that case from HyperMarkdown's streaming sentinel, so such lists are silently renumbered from 1. Preserve the original start value or mark only renderer-generated attributes before normalizing them.
Answers mentioning gpt-loading are incorrectly hidden
This substring check treats any answer that merely mentions gpt-loading as the loading placeholder. When reasoning is present, such an answer is replaced by an empty string and disappears from the rendered card even though it is retained in the conversation record. Match the actual injected placeholder element (or carry an explicit placeholder flag) rather than checking for the class name anywhere in the answer.
Probe cache ignores provider endpoint and secret changes
src/popup/sections/ApiModes.jsx:93
This key omits request inputs that live outside apiMode, notably the selected provider's endpoint and secret. Editing a custom provider or rotating its key leaves the old Reachable/Unreachable result attached to the same key, even though the next probe uses different settings. Include a request-settings revision in the key or invalidate all results when those config values change.
Probe results persist across request-setting changes
src/popup/sections/GeneralPart.jsx:123
The result is kept after the custom model URL, model name, or API key changes, so the button can continue to report the previous endpoint as reachable until the user runs another test. An in-flight result can also overwrite a result for newly edited settings. Clear or version the result whenever any request-defining setting changes.

Reviewed changes
This incremental pass covers the single commit aede3f34 pushed since the prior pullfrog review at a4c5d4c:
Truncated thinking is no longer rendered twice — finish() in openai-compatible-core.mjs now only records resolveStreamText({ final: true }).answer and no longer posts it as an answer. The final/non-final resolutions differ only in the unclosed-block branch, so no legitimate answer post is dropped; the unclosed <think>… text stays in the record while the reasoning channel remains the sole place it is displayed.
No leftover placeholder — because buildStreamedContent strips the gpt-loading placeholder whenever reasoning is present, the card shows the reasoning block once (collapsed on done) instead of a stuck spinner in the answer slot.
Test tightened — reasoning-content.test.mjs now asserts the raw block is stored but never posted as an answer and that the reasoning channel carried it; it would fail if the removed post returned.
The one open thread from the prior review (openai-compatible-core.mjs:147, the unclosed-thinking double-render) is addressed by this commit and has been resolved.

7. Answers mentioning a loading class disappear 🐞 Bug≡ Correctness
buildStreamedContent treats any answer containing the substring gpt-loading as the waiting

genuine reply mentions that class in prose or code, the renderer shows the reasoning block but drops
the reply.

- src/components/ConversationCard/index.jsx[523-529]
## Recommended Fix
Distinguish the card's actual waiting placeholder from arbitrary answer text. Match the complete placeholder markup, for example with an anchored check such as `/^<p class="gpt-loading">[\s\S]*<\/p>$/.test(children)`, or pass an explicit placeholder flag from the card.

9. Some code examples lose literal tags 🐞 Bug≡ Correctness
escapeTagsOutsideCode treats any backtick or tilde fence as closing the current fence, without
matching its delimiter or length. In a four-backtick code block containing a three-backtick line, it
escapes tags inside the code and leaves tags in subsequent prose unescaped, where the renderer can
consume them as markup.

10. Replies opening with an unclosed tag stay hidden 🐞 Bug≡ Correctness
While streaming, resolveStreamText treats an unclosed leading <think>-style block as reasoning
with answer '', so no answer is ever posted. finish() records the full text as the answer but
deliberately does not post it, so the card's content stays the gpt-loading placeholder: the reply
appears only inside the thinking block, and Copy and Read return placeholder HTML until the page
reloads.

11. Stale partial text stays shown during thinking 🐞 Bug≡ Correctness
postStreamText posts answer: '' when earlier text turns out to be the start of a <think>
block, but the card only applies answers through if (msg.answer), so the empty string is dropped.
A first chunk such as <th therefore stays displayed and in partialAnswerRef, and
buildStreamedContent sees a non-empty answer and collapses the thinking block and stops its timer
while thinking is still streaming.

Thanks again for the thorough follow-up. Most of the earlier high-priority concerns look well addressed.
Given how much the scope has grown, and since master has moved again and the branch now has conflicts, I think it would be better to split this into smaller, focused PRs, for example:
Custom API request body
Streaming rendering performance improvements
API connection test feature
HyperMarkdown / React compat migration
Reasoning-content support
This should make each change easier to review, keep the purpose of each PR clearer, and hopefully help us merge them faster.
Dependent pieces can follow one another from the latest master. Each PR should still be complete and safe to merge on its own, with its corresponding tests included, so master remains fully functional at every step.
We can keep this PR open as the reference for the existing discussion until the replacement PRs are ready.
Thanks for the guidance — splitting this as you suggested. The five focused PRs are ready, each rebuilt on the latest master and validated independently:
Each one passes npm test, npm run lint and npm run build, and the earlier review findings are folded into the PR they belong to (connection-test request semantics in #1102, reasoning lifecycle in #1104, no-KaTeX build styling in #1103). Two notes on this branch that did not survive the split as-is: the lockfile here was missing the optional dependencies of less, which npm 11 rejects as out of sync — #1103 carries a reconciled lockfile — and #1103 no longer reuses shouldDisableDefaultThinking from claude-api.mjs in the connection test, since master has since renamed it to getThinkingConfig.
One thing I could not do in this environment: manual browser testing. Each PR body lists the smoke test that would cover it. Happy to close this PR once the replacements are confirmed.

answer-buffer.mjs, with tests.detect: truecompilesevery registered grammar the first time it runs; restricting the scan keeps
auto-detection and drops that first-use cost. Explicitly labelled blocks are unaffected.
Measured on a 394-character answer, 19 chunks of 20 characters:
11.0 ms over 6 renders after.
3. React compat alias raised to 18
1e89280—react/react-dommove from@preact/compat@^17.1.2to^18.3.2sopackages declaring a React 18 peer range can be installed. The alias is a thin re-export
of
preact/compat(its entry points are 44–86 bytes), so the runtime implementation isstill
preact@10.22.1— this changes the reported version, not the rendering. Every APIthe extension uses is still exported:
unmountComponentAtNode,render,createPortal,findDOMNode,flushSync,unstable_batchedUpdates, and the hooks.4. Render replies with HyperMarkdown
0a500c9— replacesreact-markdownwith@aeven-ai/hypermarkdown, which cachessettled code lines, table rows and list items and parses only the block that is still
changing. Together with (2), a long answer no longer re-parses from the top on every
update — that was the remaining quadratic term.
Integration notes:
stream-delta.mjsturns the cumulative snapshotsthe providers emit into deltas and finalizes the stream once it ends; stored answers
render in one pass.
<think>card is gone: reasoning blocks are native. They open while themodel is thinking and collapse with a duration when it stops.

Redundancy removed:
markdown-without-katex.jsx, a 200-line near-duplicate of the renderer. The KaTeX-freebuild now swaps one module —
math-plugin.mjsformath-plugin-without-katex.mjs—through the
NormalModuleReplacementPluginhook that already existed for this purpose.Verified: the minimal build still ships zero KaTeX.
Pre.jsx, the custom code-block wrapper, now that the renderer has its own toolbar.This drops the per-block font-size selector — the renderer has no equivalent.

5. Connection test for API modes
eaf7c67— every row under Modules → API Modes gets a Test action that sends aone-token chat request and reports reachable plus latency, or the provider's own error.
It resolves the endpoint, key and model through
resolveOpenAICompatibleRequest— thesame helper the real request path uses — so a mode that passes here is a mode that can be
talked to. Token parameters go through
getChatCompletionsTokenParams, so agpt-5family mode is probed with
max_completion_tokensinstead of failing on the wrong key.Timeouts and transport failures are reported as data, never thrown. Requested in #916.
6. Show reasoning content
0c0f3fa— reasoning models put their thinking indelta.reasoning_content(DeepSeek R1)or
delta.reasoning(OpenRouter-style) rather than in the content.buildMessageAnswer()read
delta.contentand nothing else, so that text was dropped entirely and the user sawthe answer appear as if out of nowhere.
The thinking is now streamed to the card on its own channel and rendered as a reasoning
block ahead of the answer — open while it arrives, collapsed with a duration once it
stops, and re-openable afterwards.
It is deliberately not merged into the answer.
pushRecord()still stores only theanswer text, so thinking never re-enters the conversation context on the next turn, which
is what DeepSeek does with
reasoning_contenttoo. Both halves of that — thinking isshown, thinking is not sent back — are asserted in
tests/unit/services/apis/reasoning-content.test.mjs. Requested in #839.Why these changes: what the issue tracker says
