Unable to disable reasoning (Typescript SDK)

[stayingcool]

I’m unable to disable reasoning. I’ve reviewed the documentation and tried setting the following options under reasoning, but it still remains enabled:

effort: "none"
exclude: true
enabled: false
max_tokens: 0

Typescript Request Payload Sample:

{
  "model": "x-ai/grok-3-mini",
  "messages": [
    {
      "role": "system",
      "content": "You are Grok 3 Mini, a large language model from x-ai. Formatting Rules..."
    },
    {
      "role": "user",
      "content": "Which is bigger: 9.11 or 9.9?"
    }
  ],
  "stream": true,
  "streamOptions": {
    "includeUsage": true
  },
  "reasoning": {
   //  ‼️ ‼️ ‼️ What should we set here to turn off reasoning? ‼️ ‼️ ‼️
  }
}

SDK Version: package.json
