fix(models): restore gemini-3-flash-preview to Gemini OAuth picker - #37606
Merged
Conversation
#37046 swapped gemini-3-flash-preview -> gemini-3.5-flash in the google-gemini-cli (OAuth/Code Assist) picker on the premise that the preview slug was renamed. It wasn't. Per gemini-cli's models.ts, Code Assist serves two distinct flash slugs with different access gates: gemini-3-flash-preview (PREVIEW_GEMINI_FLASH_MODEL — what subscription/ free-tier OAuth users reach) and gemini-3.5-flash (DEFAULT_GEMINI_3_5_FLASH_MODEL — GA-channel-gated). The model string is passed verbatim into the {project, model, ...} envelope sent to cloudcode-pa.googleapis.com, so non-GA users got a hard error on every prompt because gemini-3.5-flash 404s for them. Offer both slugs in the OAuth picker (matching gemini-cli's own /model list) so non-GA users can select the preview flash that works. The gemini (API-key), OpenRouter, and Nous lists are untouched — google/gemini-3.5-flash is a real live model on those surfaces.

Summary
Restores
gemini-3-flash-previewto the Google OAuth (google-gemini-cli/ Code Assist) model picker so subscription/free-tier OAuth users have a working flash model again.Root cause: #37046 swapped
gemini-3-flash-preview→gemini-3.5-flashin the OAuth picker on the premise that the slug was simply renamed. It wasn't. Per gemini-cli's ownmodels.ts, Code Assist serves two distinct flash slugs with different access gates:gemini-3-flash-preview(PREVIEW_GEMINI_FLASH_MODEL) — the flash that subscription/free-tier OAuth users actually reachgemini-3.5-flash(DEFAULT_GEMINI_3_5_FLASH_MODEL) — GA-channel-gated (useGemini3_5Flash)The picked model string is passed verbatim into the
{project, model, ...}envelope sent tocloudcode-pa.googleapis.com/v1internal:generateContent, so non-GA users got a hard error on every prompt —gemini-3.5-flash404s for them.Changes
hermes_cli/models.py:google-gemini-clipicker now offers bothgemini-3-flash-previewandgemini-3.5-flash, matching gemini-cli's own/modellist. Non-GA users pick the preview slug; GA-channel users can pick either.Scope
Only the OAuth picker. The
gemini(API-key), OpenRouter, and Nous lists are untouched —google/gemini-3.5-flashis a real live model on those surfaces (OpenRouter released it May 19), so #34581 and the API-key half of #37046 were correct.Validation
