文本生成

Grok 适合生成、总结、改写、分类、抽取、实时信息问答和多轮对话。接入时优先使用 Responses API：

https://xikapi.com/v1/responses

基础文本生成

curl https://xikapi.com/v1/responses \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $XIKAPI_API_KEY" \
  -d '{
    "model": "grok-4.3-latest",
    "input": [
      {
        "role": "user",
        "content": "Write a product description in fewer than 100 words"
      }
    ]
  }'

长文本总结

长文本总结适合合同、会议纪要、报告、客服记录和知识库文档。

{
  "model": "grok-4.3-latest",
  "max_output_tokens": 1200,
  "input": [
    {
      "role": "system",
      "content": "You are a document summarization assistant. Preserve key facts, amounts, dates, responsible parties, and risks."
    },
    {
      "role": "user",
      "content": "Summarize the following contract content: ..."
    }
  ]
}

改写与润色

改写任务建议明确目标语气、长度和保留信息。

Rewrite the following support reply to be more polite and clear. Preserve the refund rules and processing timeline, and do not promise anything not stated.

分类与抽取

分类和抽取适合客服工单、反馈归因、内容审核、订单备注识别等场景。

{
  "model": "grok-4.3-latest",
  "temperature": 0,
  "max_output_tokens": 500,
  "input": [
    {
      "role": "user",
      "content": "Classify the text as complaint, inquiry, or praise. Text: I paid, but the order has not arrived."
    }
  ]
}

多轮问答

多轮问答可以由服务端维护完整历史，也可以使用 previous_response_id 继续上一轮响应。

{
  "model": "grok-4.3-latest",
  "previous_response_id": "resp_xxx",
  "input": [
    { "role": "user", "content": "Continue explaining the second point" }
  ]
}

控制输出长度

可以同时用 max_output_tokens 和提示词约束输出长度。

Answer in no more than five bullet points, each under 30 words.

生产环境建议：

• 短回复使用较小 max_output_tokens
• 总结和分析任务给足输出空间
• 对必须短输出的场景增加服务端截断或校验

控制语气和格式

把稳定要求放在 system 消息中，把本轮任务放在 user 消息中。

{
  "model": "grok-4.3-latest",
  "input": [
    {
      "role": "system",
      "content": "You are an enterprise support assistant. Be polite and concise, and do not invent policies."
    },
    {
      "role": "user",
      "content": "The user says a top-up has not arrived. Draft a support reply."
    }
  ]
}

常见 Prompt 模板

实时问答：

Search for the latest information first, then summarize the conclusion concisely. Include sources and dates.

合同总结：

Summarize the contract using this structure:
- Parties
- Scope of services
- Payment terms
- Breach liability
- Risks requiring manual review

字段抽取：

Extract name, phone number, order ID, and issue type from the text. Use null for unknown fields.

最佳实践

• 把稳定角色和边界放入 system 消息
• 对分类、抽取等任务降低 temperature
• 输出 JSON 时配合服务端解析和校验
• 需要最新信息时启用搜索工具
• 不要把 API Key 暴露在浏览器前端
