   Triage

   Thanks for the write-up and the screenshot, @MaxAnderson95! This is a real gap on current main (8ed276c246, the same commit as 0.0.46-nightly.20261003.2610).

   OpenCode 1.x copies each upstream provider's display name onto its models:

   t3code/apps/server/src/provider/Layers/OpenCodeProvider.ts

   Lines 270 to 274 in 8ed276c

   	const subProvider = nonEmptyTrimmed(provider.name);
   	models.push({
   	slug: `${provider.id}/${model.id}`,
   	name,
   	...(subProvider ? { subProvider } : {}),

   The OpenCode 2 status check never does. checkOpenCode2 keeps providerID, id, name, and variants, and leaves subProvider unset:

   t3code/apps/server/src/provider/Layers/OpenCodeProvider.ts

   Lines 542 to 550 in 8ed276c

   	const models = providerModelsFromSettings(
   	result.value
   	.map((model) => ({
   	slug: `${model.providerID}/${model.id}`,
   	name: model.name,
   	isCustom: false,
   	capabilities: openCode2ModelCapabilities(model),
   	}))
   	.toSorted((left, right) => left.name.localeCompare(right.name)),

   The picker already renders that field. On web, a set value shows as OpenCode · <subProvider>, and without it the row just says OpenCode:

   t3code/apps/web/src/components/chat/ModelListRow.tsx

   Lines 46 to 48 in 8ed276c

   	const providerLabel = props.model.subProvider
   	? `${props.providerDisplayName} · ${props.model.subProvider}`
   	: props.providerDisplayName;

   Mobile uses the same field as the row subtitle, so no client change is needed once the snapshot carries it.

   The rows aren't actually the same model. Slugs stay ${providerID}/${id}, so each click still routes to the right upstream; they only look identical, which matches the three Claude Opus 5.5 rows in your screenshot.

   model.list doesn't include the provider's display name. The OpenCode 2 client in this build (@opencode/protocol 2.0.18) returns providerID on each model and name on provider.list, but the driver only calls model.list today:

   t3code/apps/server/src/provider/Drivers/OpenCodeDriver.ts

   Lines 301 to 314 in 8ed276c

   	const loadOpenCode2Models = yield* makeOpenCode2ModelLoader(
   	openCode2Server.withConnection((connection) =>
   	connection.client.model.list({ location: { directory: serverConfig.cwd } }).pipe(
   	Effect.map((models) => models.data),
   	Effect.mapError(
   	(cause) =>
   	new OpenCodeRuntime.OpenCodeRuntimeError({
   	operation: "model.list",
   	detail: "The OpenCode server could not list its models.",
   	cause,
   	}),
   	),
   	),
   	),

   A fix should join provider.list's name onto each model as subProvider, falling back to providerID when a provider has no name. The raw id alone would separate the rows (OpenCode · anthropic) but wouldn't match the display names the 1.x path shows. Open PR #14941 fixes the same omission for Pi but doesn't cover OpenCode. The existing OpenCode 2 catalog test never asserts subProvider, so a case with one shared model name across two provider ids would lock the label in.

   There's no workaround in the picker for now, since the slug isn't shown on the row.

   Thanks for the triage! I opened #14971 with the fix as described: it joins provider.list names onto OpenCode 2 models as subProvider, falls back to providerID, and adds a test with one model name shared across two providers.

   @MaxAnderson95 thanks for the fix in #14971. I opened #15327 for the same issue and wanted to clarify the overlap and additional coverage.

   Both PRs retrieve provider names from OpenCode 2 and use them to distinguish model rows. Both support arbitrary configured provider names.

   #15327 also shows the provider in the selected model label after the picker closes, supports searching by provider name or raw provider ID when name metadata is missing, and updates selected labels in the web/desktop and mobile composer and mobile scheduled-task settings. I verified provider switching in the running web client. #14971 includes actual iOS verification; #15327 has not been tested on-device.

   If maintainers prefer to merge the smaller server fix in #14971 first, we can rebase #15327 onto it and retain the additional selected-label and search changes. Those changes could also be cherry-picked if preferred. Happy to coordinate to avoid duplicating the server fix.

   Separately, #15202 fixes a startup race that can leave custom providers out of OpenCode's returned catalog. #15327 displays provider identity for models present in that catalog; it does not fix missing models caused by that race. I have kept that discovery fix separate under the one-problem-per-PR scope.

   The android app doesn't show provider in the search preview at all even (this is on the 2.0.0 beta)

   Fixed by #17424, which landed on main in 7b09ac7. OpenCode 2 models now carry the name of the provider that listed them as subProvider, so same-named models from different providers show which one they use in the model picker (web, desktop, and mobile). Closing as completed; please open a new issue if you still see identical rows on a build that includes it.
