## Background Google Gemini API supports a `serviceTier` parameter that lets users choose between standard, flex (cheaper/slower), and priority (faster/more expensive) processing tiers. Also see: googleapis/js-genai@0bfe800 ## Summary - Add `serviceTier` provider option to the Google Generative AI provider, accepting `'SERVICE_TIER_STANDARD'`, `'SERVICE_TIER_FLEX'`, or `'SERVICE_TIER_PRIORITY'` - Fully backward compatible — the parameter is optional and defaults to omitted ## Manual Verification Run the added examples for `generateText` and `streamText`. ## Checklist - [x] Tests have been added / updated (for bug fixes / features) - [x] Documentation has been added / updated (for bug fixes / features) - [x] A _patch_ changeset for relevant packages has been added (for bug fixes / features - run `pnpm changeset` in the project root) - [x] I have reviewed this pull request (self-review) ## Future Work N/A ## Related Issues N/A
