ai@7.0.163

Vercel AI SDK patch release 7.0.163 introduces several key enhancements and bug fixes across core capabilities: - Streaming & Types: Added typed streaming heartbeat parts ( ping union variant), requiring updates to exhaustive stream-part switches. Type inference now properly handles schema unions passed to Output.object and Output.array. Stream steering messages are now streamed to the UI and retained in converted messages. - Audio & Transcription: Native URL transcription is now supported (Groq leverages this directly with a redirect fallback). Transcription telemetry event fields ( byteLength , mediaType ) may now be undefined for native fetches. Audio types are inferred from bytes when content-type headers are generic. Word timings can be exposed separately from segments with granular timestamps. - Provider & Realtime Support: Added provider-owned realtime transports ( createTransport ) and experimental RealtimeModelV4 server-side types. Google stream ordering for text and complete function calls (including standalone thought signatures) is improved and cross-provider history replay through Anthropic/Bedrock is sanitized. - Media & Storage: Legacy file-url and image-url tool result types are properly downloaded/inlined, and direct video delivery to caller-managed storage is represented via an uploadedVideos outcome. - Telemetry: Respects recordInputs and recordOutputs flags, omitting raw span results and nested content when disabled. Sanitized HTTP origins and endpoint metadata are reported for OpenAI Chat, Azure Chat, and Bedrock Mantle.

• Update exhaustive switch statements over stream parts to handle the new ping union variant.
• Verify telemetry consumers safely handle potentially undefined TranscriptionEndEvent.audio.byteLength and audio.mediaType when native URL transcription is used.
• Inspect custom video handling workflows to use uploadedVideos when models deliver directly to caller-managed storage.
