用deepseek api容易出现400错误

我用deepseek api做外链自动化发送时，经常出现API Error: 400
json
{"error":{"message":"This model's maximum context length is 131072 tokens. However, you requested 131275 tokens (131275 in the messages, 0 in the completion). Please reduce the length of the messages or completion.","type":"invalid_request_error","param":null,"code":"invalid_request_error"}}这个错误，需要重启对话，能不能加个按钮，舍弃先前的信息，这样就不会超出上下文了
