Vercel AI Updates: July 7, 2026

1. AI SDK xAI Provider Emits Provider-Executed Tool Results for Streaming Calls

Vercel. Vercel released @ai-sdk/xai@4.0.7, which emits provider-executed tool results for completed xAI Responses API streaming tool calls. The change surfaces the outcomes of tools that xAI runs server-side so applications consuming the stream receive the executed results rather than only the tool call. A matching @ai-sdk/xai@3.0.103 carries the same fix to the provider’s 3.x line. Source

2. AI SDK Core Preserves Signed Tool Approval Metadata

Vercel. Vercel shipped ai@7.0.16, a patch that preserves signed tool approval metadata when recording approval responses. The fix keeps the signatures attached to tool approvals intact through the recording step, maintaining the integrity of human-in-the-loop approval workflows in the AI SDK. Source
