Unsupported variants for grok-code #7813
Description
Description
Some models like minimax don't have any variants specified by default, so ctrl+t does nothing.
The default opencode grok code fast 1 model does contain variants for different thinking levels that ctrl+t will cycle between, but will result in the error Bad Request: Model grok-code does not support parameter reasoningEffort.

This issue might be a duplicate of existing issues. Please check:
--variantflag to rootopencodecommand #7354: Add--variantflag to rootopencodecommandThese issues address the broader challenge of properly handling model variants and reasoning efforts across different contexts. Your specific case with grok-code and minimax models lacking variant support appears to be part of the larger model variant system being improved.
For keybind-related issues, please also check our pinned keybinds documentation: #4997
Feel free to ignore if none of these address your specific case.

The issue isn't that grok-code lacks variant support. The issue is the default model configuration for grok-code contains variants that aren't actually supported and give errors if you select them.

This also occurs on the first message (not just after the Ctrl+T variant cycles) on v1.1.25:
the Grok API returns {"code":"Client specified an invalid argument","error":"Invalid arguments passed to the model."} which then causes a secondary AI_TypeValidationError because the error format is a string instead of the expected object schema.
