…ate (#14090) ## Background Google updated their Gemini API to use lowercase service tier values (`standard`, `flex`, `priority`) instead of the previous uppercase prefixed format (`SERVICE_TIER_STANDARD`, `SERVICE_TIER_FLEX`, `SERVICE_TIER_PRIORITY`). The old values no longer work. See [googleapis/js-genai@9bdc2ae](googleapis/js-genai@9bdc2ae). Also outlined in their docs: - https://ai.google.dev/gemini-api/docs/priority-inference - https://ai.google.dev/gemini-api/docs/flex-inference ## Summary - Updated the `serviceTier` provider option enum in google to accept `'standard' | 'flex' | 'priority'` - Updated tests, examples, and documentation to reflect the new values ## Manual Verification Ran the `generate-text` and `stream-text` service tier examples against the live Gemini API. ## 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
