grok 4.6 thinking/reasoning level

[joaofasilva-kitar]

I'm trying to adjust to medium the thinking level in opencode:

...
"provider"{
  "cursor": {
    "options": {
      "sandbox": false,
      "params": {
        "fast": "false"
      }
    },
    "models": {
      "grok-4.6": {
        "variants": {
          "fast": {
            "disabled": true
          }
        },
        "options": {
          "params": {
            "thinking": "medium",
            "fast": "false"
          }
        }
      }
    }
  }
}

However, in Cursor Usage the model being record is always cursor-grok-4.6-high.
Did i miss something?
