feat(local): comics, and picture edits with any image model - #2439
Comics, and pictures that any image model can edit, in the desktop app. What is now true is in Studio and agent. The lasting decisions are ADR 0089 (any image model changes a picture) and ADR 0090 (a document waits on the server for its pictures). This PR also deletes the design proposal, as docs/README.md asks of the PR that ships a feature. Its unfinished items now live in the Known gaps of studio.md, agent.md and local-models/selection.md.
One image model edits. Edit runs on the chosen image model when it takes a picture in. A model that can't redraws the picture from its prompt plus the change. The separate edit slot is now optional. Remote edits through OpenRouter go via /images with input_references instead of the 404ing /images/edits. Settings marks models that edit with an Image editing badge. Image requests carry a shape and reference pictures.
Comics in Studio. A new Comic artifact with ten kinds (western, manga, webtoon, picture book, storyboard and more) and 1 to 12 pages. The chat model plans the title, style, cast and panels. Page 1 is drawn first, and the remaining pages are drawn with page 1 as their reference so the characters stay consistent. The pages are bound into one PDF in the kind's reading order. Search finds a comic as one document.
Comics from the agent. The agent plans and draws the pages itself, then binds them with surfsense_bind_comic. Comics never go through create_artifact. A document now waits on the server for the pictures it places.
Studio UI. Image types and comic kinds are shown as illustrated cards, and ScrollFade handles rows that scroll sideways.
Fixes found while testing:
A Studio job held SQLite's write lock while it asked the API for the model's window. The API needs that lock to answer, so every lookup failed as database is locked, and other API requests failed with it.
The comic plan request now carries a JSON schema, and a reply that isn't a plan is asked for once more before any page is drawn. A model that declines the sources now fails the job with its own first line, not a JSON parse error.
A refused image request now counts as refused even when its response body is cut off.
Fixes from CodeRabbit's review:
Shapes and retries:
/images now gets the shape as aspect_ratio.
A refused edit is resent only without a field it actually carried.
Local image model:
A picture running beside a bound comic now keeps sd-server running.
Comics:
A plan with fewer pages than asked for is asked for again.
If any page is drawn by a local model, every page's lines go in the strip under it.
The strip sets Chinese, Japanese and Korean lines in fonts that have those characters, and wraps lines that have no spaces.
Waiting renders:
Cancelling a queued picture now settles the documents waiting on it.
If settling fails after a job finishes, the failure is logged instead of making Huey run the job, and bill its picture, again.
An older infographic is redrawn in Studio's style.
The agent's result for a queued picture now says a document can place it straight away.
The regenerate route's docs now give the needs_image code.
Why
Asked for a comic, the agent used to write a web page with SVG panels, or draw one picture and stop. Editing needed a second model that most users never choose, and failed outright through OpenRouter. Every picture came out in the model's default shape, so characters changed from page to page.
Fixes # (no issue)
How to test
cd surfsense_local/backend && uv run pytest tests/unit tests/integration/worker tests/integration/agent tests/integration/artifacts tests/integration/llm
cd surfsense_local/frontend && pnpm test
Four figure-reading tests (in test_figures_pictures_reading.py and test_figures_docling.py) fail on this branch and also fail with these changes stashed, so they are unrelated.
By hand, in cd surfsense_local/electron && pnpm dev:
Choose an image model under Settings › Image models. Models that take a picture in show Image editing.
Studio › Image: draw a picture, then Edit it.
Studio › Comic: pick a kind and 4 pages over an ordinary document. You should get one PDF, with characters that stay the same across pages.
Ask the agent for a short comic. It confirms the page count, draws the pages, and opens the bound comic.
Make a comic from a source the model will refuse. The job should fail with the model's own words, and the artifact list should keep loading without database is locked errors.
Summary by CodeRabbit
New Features
Create comics in Studio by choosing a style and page count, then view the finished comic as a PDF.
Ask the agent to create or update comics, or bind ordered pictures into a comic.
Generate pictures with a chosen shape and reference images.
Improvements
Edit pictures with a model that supports image input; otherwise, changes are redrawn from the original prompt.
Studio documents can wait for pictures that are still being drawn and continue rendering when they’re ready. If a required picture fails, the document reports which one.
… shape and references
The image model edits when it takes a picture in, read from its connection's
input_modalities or the catalog; the image_edit slot becomes an optional
override, and with no model that takes pictures an edit is drawn again from
the prompt the picture was drawn with. Pictures go to /images/edits, or to
/images with input_references where a server has no edit route, as
OpenRouter. surfsense_make_image takes shape and references, so a comic's
pages keep page 1's characters, and never points the agent to Settings.
…hat plans them
The surfsense-pictures skill plans a set of pictures with a character sheet,
confirms the count once, draws the first page alone and the rest with it as
their reference, and binds them with a script that places each page as JPEG,
setting a page's exact lines under it when its lettering came out wrong. The
prompt sends pictures and comics there, and the web page skill sends them away.
A render naming a picture still being drawn is made pending with the pictures
it waits for and answers at once. The end of every Studio job queues the
renders waiting on that picture once all of theirs are drawn, or fails one
whose picture failed, saying which; one update takes the wait off, so two
pictures ending together queue it once. The worker does the same at start.
…s that edit
The Edit box needs only an image model, and says when a change is drawn again
because the model takes no picture in; it never sends the user to the image
editing models. Image models that take a picture in carry an Edits label,
tooltip "Can edit pictures", and the editing models become an optional
"Use a different model for edits". Translated into every shipped language.
… for their pictures
Studio and the agent describe what is now built; ADR 0089 records that any
image model changes a picture, amending ADR 0077, and ADR 0090 that a document
waits on the server for its pictures, amending ADR 0087. The user docs say what
Edit does on each kind of model and how the agent makes a comic. The proposal
stays in progress, with where the build differs and what is left.
… engines
comics.md covers Western comics, graphic novels, bande dessinée, manga,
manhua, manhwa and webtoons, comic strips, yonkoma, picture books and
storyboards: how each reads, how its pictures are shaped and bound, and how it
looks. The binding script reads a manga right to left and stacks a webtoon down
one long page. A test builds Claude Code's skills plugin from the shipped
skills, so a Claude plan thread gets the pictures skill as opencode does.
…, not an Edits label
Beside Image generation it reads as one of the model's types and needs no
tooltip, so the Edits component, its tooltip and its strings go.
The dialog shows one Image card whose Type switch picks image or infographic and sends that format's key, so edits and the agent's tool see no change. Each format's options now come from its own hook in format-options/, the podcast brief among them.
Page by page at comic-book width or one long scroll, right to left for a manga, pages placed as JPEG, a page's exact lines set in a strip under it. Studio's comics and the agent's will share it.
A comic format with options kind and pages, one of ten kinds and 1 to 12 pictures. The chat model plans the cast, style and panels; page 1 is drawn alone and the rest with it as reference; a local model draws no words and every line goes in the strip. A failed comic is never retried, since every page would be billed again.
A Comic card opens a kind and a page count, each kind at its own length, with one line on what the pictures cost; the comic opens in the PDF viewer. Translated, with comic added to the glossary.
…sense_bind_comic
bind_comic takes the pictures' names in reading order, with lines for a page's strip, a layout and a direction, and artifact_id for the comic's next version. A page still being drawn makes the comic wait. The job binds with the shared binder and asks no model, so it starts no local image model. The skill binds with it, and pdf.md's script is gone.
…e comic
make_image takes comic_page for each page, binding marks any page drawn without it, and a page's edits keep the mark. The artifacts list leaves pages out, so Studio, mentions and the jobs dialog show the comic alone; a page still opens from the step that drew it. Deleting a comic deletes the pages and their versions that no other comic binds and no document places.
…were drawn from
A comic's page is not indexed, and binding takes a page drawn without the mark out of the index. The comic's text is its title, each page's drawing prompt with a line every page repeats kept once, and the lines under its pages, since its bubbles are drawn and its PDF holds no text for them.
The comic artifact proposal, Studio's comic format and the agent's binding in the architecture docs, and the Comic format, its kinds and Image's Type in the user docs.
Image and Infographic are cards with their own pictures, the chosen one bordered and ticked, as a radio group still. The pictures are drawn on the theme's tokens and registered as icons, ImageTypeIcon and InfographicTypeIcon.
Image is a photo print over another, a landscape under a sun; Infographic a sheet with a donut, a bar chart and a trend line. Each carries its own colours and a gradient backdrop that fills its card, so it reads the same in light and dark; the card's hover and selection moved to its border.
Each of the ten kinds has its own picture, drawn on a shared frame and registered as icons. Kind is a row of cards that scrolls inside the dialog, with a fade at either edge and arrows only where more kinds lie; Pages stays a dropdown beside the cost line. Image's types and the kinds share one card.
OpenRouter has no /images/edits and sometimes hangs up partway through the body of its 404. Both image clients read the whole reply before its status, so that 404 failed a comic's later pages instead of sending them to /images. A refusal is now decided by its status alone; only a success must arrive whole.
…s window
The job held SQLite's write lock while asking the API for the window, and the API needs that lock to answer, so every lookup timed out as database is locked and failed the API's other requests with it.
…l says so
The plan request carries a schema, a reply that is not a plan is asked for once more before any page is drawn, and a model that declines fails the job with its own words instead of a JSON parse error.
The PR adds a Studio Comic format and an agent tool for binding pictures into comic PDFs. It also adds picture-input model selection, shape and reference-image support, redraw fallback for edits, and server-side waiting for renders that use unfinished pictures.
Changes: Picture workflows and model behavior

Summary
Picture model selection and provider support surfsense_local/backend/modules/llm/..., surfsense_local/backend/tests/unit/llm/*, surfsense_local/backend/tests/integration/llm/test_picture_model.py
Model discovery uses declared image-input modalities to identify picture-taking models. The API reports the selected picture source. Image generation and editing accept shape information, and editing accepts multiple reference images.
Picture creation and edit fallback surfsense_local/backend/modules/agent/tool_endpoint/make_image.py, surfsense_local/backend/modules/artifacts/drawn_images/*, surfsense_local/backend/worker/studio/media/visual/*, surfsense_local/frontend/src/features/studio/*
The image tool uses type instead of style and accepts shape, references, and a comic-page flag. Artifacts retain drawing prompts. When no picture-taking model is available, edits redraw from the saved prompt and requested change.
Renders record unfinished picture IDs and return pending status. Workers queue renders when pictures are ready or fail them when a required picture is missing or fails.
A new pictures skill documents picture and comic workflows. Agent tool guidance and shipped-skill configuration reference it.

Summary
Comic artifacts and lifecycle surfsense_local/backend/modules/artifacts/comic/*, surfsense_local/backend/modules/artifacts/formats.py, surfsense_local/backend/modules/artifacts/router.py
The backend adds ten comic kinds, option validation, binding recipes, comic-page metadata, versioning, unused-page cleanup, and the Comic format. Comic pages are omitted from artifact listings.
Agent binding and worker rendering surfsense_local/backend/modules/agent/tool_endpoint/bind_comic.py, surfsense_local/backend/worker/studio/*/comic*, surfsense_local/backend/worker/studio/job.py
The agent can bind ordered pictures and optional text into a comic. The Studio worker plans pages, draws and binds comics, or renders an existing binding as a PDF.
Studio controls and presentation surfsense_local/frontend/src/features/studio/*, surfsense_local/frontend/src/components/ui/*, surfsense_local/frontend/translations/*
Studio adds comic kind and page-count controls, groups Infographic under Image, displays comics with the PDF viewer, and adds comic icons and translated labels.

Summary
ADRs and documentation docs/adr/*, docs/architecture/*, www/content/docs/v2/*, .agents/skills/translate/glossary.md
Two ADRs document picture-input selection and waiting renders. Architecture documents, guides, and the translation glossary describe the picture and comic changes.
Tests cover model selection, redraws, references, pending renders, comic planning and binding, artifact lifecycle, Studio options, and agent step labels.

Explanation
The title names two main changes in the changeset: comic artifacts (Studio comic format, comic binding, and the surfsense_bind_comic tool) and picture edits that work with any image model (redraw fallback when the model cannot accept pictures). Both are central to the PR objectives. The title is short, uses a conventional feat(local) prefix, and avoids vague wording. It does not mention the many supporting changes, such as ADRs, shape handling, and the waiting-render behavior, but the task does not require full coverage.

…cases
/images takes a shape as aspect_ratio, a refused edit is resent only without a field it carried, a picture running beside a bound comic keeps sd-server, and an older infographic redraws in Studio's style.
…ever redraws
Cancelling a queued picture settles what waits on it, a settle that fails at a job's end is logged rather than retried, and the queued picture's result says a document can place it now.
A plan short of its pages is asked for again, any page drawn locally moves every line to the strip, and the strip sets Chinese, Japanese and Korean in fonts that have them, wrapping lines with no spaces.
Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Test word wrapping through the generated PDF.
This test calls the private _wrapped helper. A safe binder refactor can therefore break the test without changing the PDF output. Use bind and inspect the PDF text and placement to verify that wrapping preserves characters without inserting spaces.
