Major Changes

• 832f86f: fix(anthropic): remove cacheCreationInputTokens from providerMetadata

• ef992f8: Remove CommonJS exports from all packages. All packages are now ESM-only ("type": "module"). Consumers using require() must switch to ESM import syntax.

• 8359612: Start v7 pre-release

• 04e9009: chore: make provider implementations code patterns more consistent, including renaming certain exported symbols

  For all externally exported symbols that were renamed, the old names continue to work via deprecated aliases.

• bb93832: fix(vertex-anthropic): support eu/us multi-region anthropic endpoints

• 7fc6bd6: Raise minimum supported Node.js version to 22. Supported versions: 22, 24, and 26.

• 0c4c275: trigger initial canary release

• ebb02ea: feat(google-vertex): add the anthropic tool search tools

• b70f6ec: fix(google-vertex): support for eu/us multi region gemini endpoints

• 9bd6512: feat(provider): change file part data property to be tagged with a type and remove the image part type

• 258c093: chore: ensure consistent import handling and avoid import duplicates or cycles

• 546cefe: feat(provider/google): add gemini-3.5-flash

• 96d056d: fix(provider/google-vertex): avoid recreating Node GoogleAuth clients for repeated requests

  Create Google auth token generators per provider instance instead of using a
  module-level shared GoogleAuth cache. This avoids unnecessary GoogleAuth
  recreation when googleAuthOptions are omitted or when multiple provider
  instances use equivalent auth settings.

• a34b997: feat (provider/google-vertex): add support for maas models

• 780e563: feat(provider/google-vertex): allow overriding Vertex Anthropic auth token generation

• 427a596: Route gemini-embedding-2 / gemini-embedding-2-preview to the :embedContent endpoint, which is the only one those models support (:predict returns 400 FAILED_PRECONDITION)

• 0416e3e: feat (video): add first-class generateAudio call option

• b3976a2: Add workflow serialization support to all provider models.

  @ai-sdk/provider-utils: New serializeModel() helper that extracts only serializable properties from a model instance, filtering out functions and objects containing functions. Third-party provider authors can use this to add workflow support to their own models.

  All providers: headers is now optional in provider config types. This is non-breaking — existing code that passes headers continues to work. Custom provider implementations that construct model configs manually can now omit headers, which is useful when models are deserialized from a workflow step boundary where auth is provided separately.

  All provider model classes now include WORKFLOW_SERIALIZE and WORKFLOW_DESERIALIZE static methods, enabling them to cross workflow step boundaries without serialization errors.

• 0d8f107: feat(provider/anthropic): add support for Opus 4.7 and relevant API enhancements
