报错分析报告
1.错误翻译
原文：`top_p` must be greater than or equal to 0.95 or unset when thinking is enabled.
译文：当启用思考（thinking）功能时，`top_p` 参数必须大于等于 0.95 或未设置。
2.原因分析
claude-sonnet-4-6-thinking 模型时，启用了「扩展思考」功能，但传入的 top_p 参数值小于 0.95 且未被移除。 top_p 配置不符合扩展思考的要求。3.解决方案
调整
top_p 参数为 ≥0.95 或直接移除该参数（unset）： # 示例：Python API调用修复（以requests为例）
import requests
api_url = "https://api.dmxapi.com/v1/chat/completions"
headers = {"Authorization": "Bearer YOUR_API_KEY"}
payload = {
"model": "claude-sonnet-4-6-thinking",
"messages": [{"role": "user", "content": "你的问题"}],
"thinking": {"enabled": True}, # 启用扩展思考
# 方案1：设置top_p≥0.95
"top_p": 0.95,
# 方案2（推荐）：直接移除top_p参数（注释或删除该行）
# "top_p": 0.8 # 原错误配置（需删除）
}
response = requests.post(api_url, headers=headers, json=payload)
4. 预防措施
---
注：修复后需重新发起请求，确保 top_p 符合要求。
