Major Changes

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

• c29a26f: feat(provider): add support for provider references and uploading files as supported per provider

• 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.

Patch Changes

• 38fc777: Add AI Gateway hint to provider READMEs

• 023550e: Deprecate streamText result fullStream in favor of stream.

• 74d520f: feat: migrate providers to support new top-level reasoning parameter

• 45b3d76: fix(security): prevent streaming tool calls from finalizing on parsable partial JSON

  Streaming tool call arguments were finalized using isParsableJson() as a heuristic for completion. If partial accumulated JSON happened to be valid JSON before all chunks arrived, the tool call would be executed with incomplete arguments. Tool call finalization now only occurs in flush() after the stream is fully consumed.

• 9f0e36c: trigger release for all packages after provenance setup

• 58a2ad7: fix: more precise default message for tool execution denial

• 7bf717f: feat: Groq support for performance service tier

• f7295cb: revert incorrect fix https://github.com/vercel/ai/pull/13172

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

• f807e45: Extract shared StreamingToolCallTracker class into @ai-sdk/provider-utils to deduplicate streaming tool call handling across OpenAI-compatible providers. Also adds missing generateId() fallback for toolCallId in Alibaba's doGenerate path and ensures all providers finalize unfinished tool calls during stream flush.

• 0c4c275: trigger initial canary release

• 6fd51c0: fix(provider): preserve error type prefix in getErrorMessage

• 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

• b8396f0: trigger initial beta release

• 90e2d8a: chore: fix unused vars not being flagged by our lint tooling

• 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.
