GLM-5.1 Overthinks More in Claude Code

A Reddit user reports that GLM-5.1, running locally with Claude Code and reasoning enabled, tends to overthink tasks and keep scanning large portions of the repo even after the model seems to acknowledge the problem. They say a reasoning budget helps in the web UI, but not in Claude Code, and that GLM-4.7 did not behave this way for them.

// ANALYSIS

Hot take: this reads less like a raw capability regression and more like an agent-prompting mismatch between GLM-5.1’s reasoning style and Claude Code’s tool loop.

–The complaint is specifically about agent behavior, not core model quality.
–The issue seems tied to Claude Code orchestration: the model keeps exploring instead of stopping after a satisfactory answer.
–The user’s settings suggest a high-exploration setup (`temp=1.0`, `top_k=40`, `top_p=0.95`, reasoning on), which likely amplifies the effect.
–Compared with GLM-4.7, GLM-5.1 may be more aggressive about self-checking and context gathering in coding workflows.
–This is anecdotal, but it matches a common failure mode for coding agents: too much search, not enough commitment.
