…-4-7 (#15288) ## Summary Fixes #14773. Bedrock rejects `output_config.format` for `claude-opus-4-7` (including the `us.`/`eu.` cross-region inference profiles) with: ``` output_config.format: Extra inputs are not permitted ``` `packages/amazon-bedrock/src/anthropic/amazon-bedrock-anthropic-provider.ts` previously hardcoded `supportsNativeStructuredOutput: true` for every Bedrock-Anthropic model. The Anthropic capability table already lists opus-4-7 as supporting structured output, so the SDK took the native path that Bedrock then refused, and any `output` / `Output.object(...)` call against opus-4-7 (including reasoning runs) failed before the model ran. This changes the flag to `!modelId.includes('claude-opus-4-7')`. Other Bedrock-Anthropic models stay on the native path; opus-4-7 falls back to the `jsonResponseTool` path, which Bedrock accepts. Using `includes()` covers the direct `anthropic.claude-opus-4-7` id and both cross-region inference profiles (`us.anthropic.claude-opus-4-7`, `eu.anthropic.claude-opus-4-7`). ## Test plan - [x] Added a parameterized test for the direct id and both cross-region prefixes. The existing default-model assertion still requires `supportsNativeStructuredOutput: true` for non-opus-4-7 models. - [x] `pnpm --filter @ai-sdk/amazon-bedrock test`: 369/369 pass (node + edge) - [x] `pnpm check`: lint and format clean - [x] `pnpm --filter @ai-sdk/amazon-bedrock type-check` --------- Co-authored-by: Aayush Kapoor <aayushkapoor34@gmail.com>
