我试了以下几种方法都不行 
curl参数 
curl http://localhost:11434/api/chat -d '{
  "model": "qwen3:4b",
  "messages": [{

    "content": "What is the answer of 1 + 1?"
  }],
  "think": false,
  "stream": false
}'

  "model": "qwen3:4b",
  "messages": [{
    "role": "user",
    "content": "What is the answer of 1 + 1? /no_think"
  }],
  "stream": ...
