   @remorses we are gonna make it a lot easier in the future rn you can do this:

   {
     "$schema": "https://opencode.ai/config.json",
     "provider": {
       "opencode": {
         "models": {
           "glm-4.6": {
             "options": {
               "reasoning": {
                 "enabled": false
               }
             }
           }
         }
       }
     }

   On the Cerebras provider, this seems to do the trick:

     "provider": {
       "cerebras": {
         "models": {
           "zai-glm-4.6": {
             "name": "Z.AI GLM 4.6",
             "options": {
               "disable_reasoning": true
             }
           }
         }
       },
     }
