New Models/MutableModels/createModels collection: provider map, async
model listing (best-effort aggregation), getAuth decision tree with
double-checked locked OAuth refresh, stream/complete with per-field
auth merge over lazyStream.
Auth substrate: ProviderAuth { apiKey?, oauth? }, one type-tagged
credential per provider, CredentialStore (read/modify/delete; modify
is the only write path, serialized RMW), OAuthAuth login/refresh/toAuth
split, prompt()/notify() login callbacks, browser-safe default
AuthContext.
types.ts: Provider alias renamed to ProviderId; ApiOptionsMap and
ApiStreamOptions<TApi> for typed per-API stream options; hasApi()
runtime narrowing guard.
When Bedrock rejects a request with "data retention mode '<mode>' is not
available for this model", append a pointer to the AWS data retention
documentation so users can configure a supported mode.
Application inference profile ARNs encode the region
(arn:aws:bedrock:<region>:<account>:...) but the provider ignored it,
falling through to AWS_REGION which may point to a different region.
Extract the region from the ARN when present, taking priority over
environment variables.
Fixes#4860
- Update GitHub Copilot tests to use available models (claude-haiku-4.5, gemini-2.5-pro)
- Update OpenRouter tests to use available models (google/gemini-2.5-flash, deepseek/deepseek-chat)
- Fix over-broad sed that incorrectly renamed OpenAI Responses gpt-4o test
- Remove nvidia.md from repo root
- Update packages/ai/CHANGELOG.md
Honour StreamOptions.headers in the Bedrock provider by attaching a
Smithy build-step middleware that merges caller headers into the
request before SigV4 signing. Reserved headers (x-amz-*, authorization,
host) are silently skipped to preserve signing and the bearer-token
auth path. No-op when no headers are supplied. Updates the
StreamOptions.headers JSDoc to drop the Bedrock caveat.
