BREAKING: SpaceXAI has released a major new update for Grok Build (v1.0.13).

The update improves reliability with automatic retries and recovery from truncated responses, inference failures, oversized images and session-saving issues.

It also adds smarter hooks, better Windows support, faster MCP and session startup, improved scheduled tasks and quicker compressed CLI downloads.

Features

• Length-truncated responses now continue automatically instead of failing the turn.
• Hooks can now ask the user to confirm a tool call instead of always allowing or denying.
• Hooks can now request deferral or add context shown to the model after a tool runs.
• Session close now records detailed timing data for performance analysis.
• Credit limit upsell now offers a Try Again button to retry the last prompt.
• Pasted images now show a live pixel preview in the prompt box on iTerm2.

Bug Fixes

• Transient inference failures (stalls, drops, 5xx) now retry automatically instead of ending the turn.
• Windows users can now correctly open ~/.grok and worktree sessions.
• Session data is now more reliably saved after prompts and on power loss.
• Compaction failures now show the actual error instead of a generic message.
• Truncation error messages now show the right guidance instead of suggesting an unhelpful retry.
• Truncated tool calls are now executed instead of failing the turn when arguments are complete.
• Images larger than 2000px no longer brick sessions on many-image requests.
• Wrapped hyperlinks in the pager now remain fully clickable on Windows Terminal instead of only the first line.
• Recurring scheduled tasks now include a reminder to stop the monitor when work finishes.
• Scheduled task IDs are now full UUID strings, preventing collisions when tasks are created in the same millisecond.

Performance

• Subagent spawning is faster when connections drop during bursts.
• Session startup with MCP servers is now much faster when auth is already configured.
• MCP server startup no longer stalls behind a fixed batch size.
• CLI downloads are now compressed, making fresh installs and updates substantially faster.
