What happened?

I choose (openrouter) deepseek/deepseek-v4-pro • xhigh, then try to send a message and it shows error:

Error: 400 reasoning_effort: Invalid option: expected one of
"xhigh"|"high"|"medium"|"low"|"minimal"|"none"

But it is xhigh.

With 'high' it works.

Also, I tried to set it in models.json like this, but pi didn't show xhigh at all in that case:

"reasoning": true, "compat": { "requiresReasoningContentOnAssistantMessages": true, "thinkingFormat": "deepseek", "reasoningEffortMap": { "minimal": "high", "low": "high", "medium": "high", "high": "high", "xhigh": "max" } }

Steps to reproduce

(openrouter) deepseek/deepseek-v4-pro • xhigh

Expected behavior

xhigh maps to max reasoning
