Grok Build version 1.0.13 is released with significant reliability and performance improvements. Key updates include automatic continuation of truncated responses, retry on transient inference failures, and execution of tool calls once arguments are complete. Hooks are now more powerful, supporting user confirmation, deferred execution, and context injection. The release also fixes issues with large images and Windows worktrees, and speeds up subagent spawning and MCP startup.
