205077b: fix: improve Zod compatibility - Updated dependencies [205077b] - @ai-sdk/provider-utils@3.0.0-beta.4 - @ai-sdk/gateway@1.0.0-beta.9 ## 5.0.0-beta.21 ### Patch Changes - 38ae5cc: feat (ai): export InferUIMessageChunk type - faea29f: fix (provider/openai): multi-step reasoning with text - 90ac328: fix (ui): tool part metadata support in ui messages - 4a1e0c8: fix(ai-cli): fix bundling and improve authentication error handling - 30ac566: fix (ui): text message metadata support in ui messages ## 5.0.0-beta.20 ### Patch Changes - 4c8f834: feat: automatically respect rate limit headers in retry logic Added automatic support for respecting rate limit headers (`retry-after-ms` and `retry-after`) in the SDK's retry logic. When these headers are present and contain reasonable values (0-60 seconds), the retry mechanism will use the server-specified delay instead of exponential backoff. This matches the behavior of Anthropic and OpenAI client SDKs and improves rate limit handling without requiring any API changes. ## 5.0.0-beta.19 ### Patch Changes - 10b21eb: feat(cli): add ai command line interface - 75c3396: fix (ai): handle errors in 2nd streamText doStream call - 05d2819: feat: allow zod 4.x as peer dependency - db64cbe: fix (provider/openai): multi-step reasoning with tool calls - Updated dependencies [05d2819] - @ai-sdk/provider-utils@3.0.0-beta.3 - @ai-sdk/gateway@1.0.0-beta.8 ## 5.0.0-beta.18 ### Patch Changes - d3960e3: selectTelemetryAttributes more robustness - 9338f3e: fix (ai): throw error for v1 models ## 5.0.0-beta.17 ### Patch Changes - Updated dependencies [c190907] - @ai-sdk/gateway@1.0.0-beta.7 ## 5.0.0-beta.16 ### Patch Changes - Updated dependencies [9e16bfd] - @ai-sdk/gateway@1.0.0-beta.6 ## 5.0.0-beta.15 ### Patch Changes - 8e31d46: feat (ai): export SourceDocumentUIPart ## 5.0.0-beta.14 ### Patch Changes - Updated dependencies [30ab1de] - @ai-sdk/gateway@1.0.0-beta.5 ## 5.0.0-beta.13 ### Patch Changes - 377bbcf: fix (ui): tool input can be undefined during input-streaming - ce1d1f3: feat (ai): export mock image, speech, and transcription models - c040e2f: fix (ui): inject generated response message id - c808e4d: fix (ui): do not send changing assistant message ids when onFinish is provided ## 5.0.0-beta.12 ### Patch Changes - fc0380b: feat (ui): resolvable header, body, credentials in http chat transport - 51f497d: feat (ai): step input message modification in prepareStep - 4f3776c: feat (ai): add InferUITools helper ## 5.0.0-beta.11 ### Patch Changes - 9e40cbe: Allow destructuring output and errorText on `ToolUIPart` type ## 5.0.0-beta.10 ### Major Changes - 2b637d6: chore (ai): rename UIMessageStreamPart to UIMessageChunk ### Patch Changes - 16ccfb2: feat (ai): add readUIMessageStream helper - 90ca2b9: feat(ai): Record tool call errors on tool call spans recorded in `generateText` and `streamText`. - af1d5a5: fix(ai): Unexpected reasoning-start event in extract reasoning middleware ## 5.0.0-beta.9 ### Patch Changes - 86cfc72: feat (ai): add ignoreIncompleteToolCalls option to convertToModelMessages ## 5.0.0-beta.8 ### Patch Changes - 6909543: feat (ai): support system parameter in Agent constructor - c8fce91: feat (ai): add experimental Agent abstraction - 9121250: Expose provider metadata as an attribute on exported OTEL spans - Updated dependencies [97fedf9] - @ai-sdk/gateway@1.0.0-beta.4 ## 5.0.0-beta.7 ### Patch Changes - 60132dd: fixed date formatting for updated mcp protocol version ## 5.0.0-beta.6 ### Patch Changes - 143c55b: feat (ai): export Chat callback types - f04ffe4: feat (ui): add onData callback to Chat - 97c35c0: feat (ui): transient data parts - fccf75c: update mcp protocol version ## 5.0.0-beta.5 ### Patch Changes - 4f3e637: fix (ui): avoid caching globalThis.fetch in case it is patched by other libraries ## 5.0.0-beta.4 ### Patch Changes - 09f41ac: fix (ui): add message metadata in Chat.sendMessage ## 5.0.0-beta.3 ### Patch Changes - Updated dependencies [f3639fa] - Updated dependencie
