Description
Description
I am trying to switch the thinking / reasoning mode of with an entry in my opencode.json:
{
"$schema": "https://opencode.ai/config.json",
"provider": {
"zai": {
"models": {
"glm-5": {
"options": {
"reasoning": {
"enabled": false
}
}
}
}
}

Has anyone the correct syntax or is there a keyobard shortcut or "/" command to disable this behavior?

Operating System

This issue might be a duplicate of existing issues. Please check:
disable_reasoningparameter for GLM/Cerebras models (open, same core problem — no way to disable thinking/reasoning for GLM models in config)If your issue is specifically about the
options.reasoning.enabled: falseconfig syntax not being honored, that may be a distinct bug worth keeping separate. Otherwise, consider whether #11987 already tracks the underlying missing feature.passystems-tus commentedon Feb 27, 2026
