Skip Grok 4.1 for Agentic Work

Date: 2026-02-22 Version: OpenClaw 2026.2.21-2 (35a57bc)

xai/grok-4-1-fast-reasoning is not reliable for agentic tasks. Common failure modes: claiming to have read a file without doing so, reporting completed actions that never happened, and fabricating errors. The hallucinations are frequent enough to make it unusable for any multi-step work where you need to trust tool results.

Stick to Claude (Sonnet/Opus) or GPT Codex 5.2+ for anything agentic.
