## 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

…PI (#14393) ## Background Follow up to #13915 and #14090: Turns out the Vertex API did _not_ apply the same change the Gemini API did, which originally prompted the #14090 follow-up. The Vertex API does not support the values `standard`, `flex`, and `priority` - instead it expects `SERVICE_TIER_{UPPERCASE_VALUE}`. ## Summary Sanitizes the input value accordingly if the Google provider implementation is used with Vertex. ## Manual Verification Run the new examples to verify. ## Checklist <!-- Do not edit this list. Leave items unchecked that don't apply. If you need to track subtasks, create a new "## Tasks" section Please check if the PR fulfills the following requirements: --> - [x] Tests have been added / updated (for bug fixes / features) - [ ] 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)
