})

const response = await client.chat.completions.create({
  model: 'claude-haiku-4-5',

  max_tokens: 100
})

console.log(response.choices[0].message.content)

聊天补全接口

  "max_tokens": 1000,

    "model": "claude-haiku-4-5",
    "messages": [{"role": "user", "content": "你好"}],
    "stream": true
  }'
