…without reasoning (#14126) ## Background #12980 The bedrock converse API path (bedrock('anthropic.claude-...')) only used native structured output when thinking/reasoning was enabled. Without thinking, it always fell back to a JSON tool workaround, even for models like Claude 4.5/4.6 that natively support structured output on bedrock. ## Summary changed the condition to use model capability OR thinking enabled 9since we already have a function `getModelCapabilities()` to check if the model natively supports structured output ## Manual Verification na ## Checklist - [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) ## Related Issues fixes #12980
