Should hopefully add this in today. Was holding off for a little while it was rolling out to avoid too many broken sessions.

I have Coder 0.5.2 and it still fails. When I ask it for the reason I get this:

No new repo work is required for this question; just note that the recent agent failures with code-gpt-5.1 / code-gpt-5.1-codex-mini are caused by the runner sending an unsupported reasoning.effort: "xhigh" value, and adjust future agent.create calls to either omit those models or include gemini-3-pro alongside Claude until the configuration is corrected.

(I asked for both Gemini 3.0 Pro and failure of code-gpt-5.1.

Can I provide more logs or anything to help you fix it?
