错误翻译

Line 1467: data: ... "delta":{"content":",\\n SUM("} ...  // 数据片段，包含部分生成的文本内容，但可能不完整。
Line 1469: data: ... "finish_reason":"max_tokens" ... // 数据片段，表示生成已达到最大 token 限制。
Line 1471: data: ... "choices":[],"usage":{...} ... // 数据片段，表示没有生成结果，但提供了 token 使用情况。
Line 1473: data: [DONE] // 数据流结束标记。

原因分析

模型响应被截断，可能由于请求的 max_tokens 设置不足，导致模型在完成生成前就停止了。

解决方案

增加 API 请求中的 max_tokens 参数值，确保其足够大以允许模型生成完整的响应。

预防措施

• 在发送 API 请求时，根据预期的响应长度，合理设置 max_tokens 的值。
• 监控 API 响应的 finish_reason，如果频繁出现 "max_tokens"，则需要考虑调整此参数或优化 Prompt。
