feat(ai-gemini): add gemini-3.6-flash and gemini-3.5-flash-lite by NachoVazquez · Pull Request #1041 · TanStack/ai

NachoVazquez · 2026-08-02T03:16:23Z

🎯 Changes

Google GA'd gemini-3.6-flash and gemini-3.5-flash-lite; only gemini-3.5-flash was already in @tanstack/ai-gemini. Without meta entries the new IDs are absent from GEMINI_MODELS, the combined tools+schema allow-list, and the per-model type maps that gate provider options, tools, and input modalities.

This PR adds both stable chat models, puts them on the combined tools+schema path, and corrects adjacent 3.5 Flash tool metadata against the official model cards:

Model	In / out tokens	$/1M in · cached · out	Tools (notable)
`gemini-3.6-flash`(new)	1,048,576 / 65,536	$1.50 · $0.15 · $7.50	+ `google_maps`, `computer_use`
`gemini-3.5-flash-lite`(new)	1,048,576 / 65,536	$0.30 · $0.03 · $2.50	+ `google_maps`; no`computer_use`
`gemini-3.5-flash`(existing, fixed)	unchanged limits/pricing	unchanged	was missing `google_maps` + `computer_use`

No cyber-only / image / TTS / video variants. No removals. gemini-3.5-pro is not GA on the checked Gemini API model pages.

Files to review (7, +308 / −31):

File	Why
`packages/ai-gemini/src/model-meta.ts`(start here)	New consts, `GEMINI_MODELS`, combined-tools set, all three type maps, 3.5 Flash tool fix
`packages/ai-gemini/tests/tools-per-model-type-safety.test.ts`	Tool accept/reject cases for 3.6, 3.5 Flash, 3.5 Flash-Lite
`packages/ai-gemini/tests/model-meta.test.ts`	Provider-options + modality type coverage
`examples/ts-react-chat/...`	Dropdowns + structured-output default → `gemini-3.6-flash`
`.changeset/gemini-3-6-flash-3-5-flash-lite.md`	minor on `@tanstack/ai-gemini`

- Around line 746-750: Update the knowledge_cutoff field in GEMINI_3_6_FLASH to
represent March 2026, using month-level precision rather than inventing a
specific day; preserve the remaining model metadata unchanged.
- Around line 991-1008: Restrict the option contracts for GEMINI_3_6_FLASH,
GEMINI_3_5_FLASH, and GEMINI_3_5_FLASH_LITE in
packages/ai-gemini/src/model-meta.ts:991-1008 to model-specific types that omit
unsupported modalities, generation, and deprecated or restricted sampling
fields; keep the metadata contracts at
packages/ai-gemini/src/model-meta.ts:779-785 and
packages/ai-gemini/src/model-meta.ts:855-861 aligned with the exported map.
Update packages/ai-gemini/tests/model-meta.test.ts:198-215 to assert supported
fields and reject unsupported options instead of relying on generic BaseOptions
assertions.
