This issue might be a duplicate of existing issues. Please check:

  • #8618: [BUG] GLM Coding Plan Pro (5/mo) unusable due to undocumented concurrent request limit of 1 - directly addresses the "High concurrency" error you're experiencing with GLM-4.7
  • #8431: GLM 4.7 AI_JSONParseError - related GLM-4.7 model issues
  • #8102: MCP Tool JSON Parsing Errors on OpenCode (GLM-4.7) - another GLM-4.7 problem

Feel free to ignore if none of these address your specific case.

it is not a bug, the model is being used heavily by everyone since its free.

这不是bug,这个模型因为免费,大家都在大量使用。

我使用自己中转站的也会触发这个,我都没有调用GLM,为什么还会触发?

https://github.com/Fast-Editor/Lynkr Use this to connect z.ai models to claude code
It handles 400 errors and all forms of errors with glm models well.

I can confirm too. I use GLM Coding Pro-Yearly Plan and I can use opencode only for 3 sessions only in same times. If this error message come from API then it might be limitation of GLM itself.

I have no idea how you are able to use even a single session, when I tried, API was blocking access momentary. It looks like opencode uses several threads and I have no idea how to limit concurrent usage.

I get this error on the coding plan!
