🐛 问题描述

nextchat似乎未等到deepseek输出完成就截断了与api的连接，类似于下面这种情况：

......
data: {"id":"52da55b8-1a63-4d68-8482-2fd79760b062","object":"chat.completion.chunk","created":1738915294,"model":"deepseek-reasoner","system_fingerprint":"fp_7e73fd9a08","choices":[{"index":0,"delta":{"content":"年","reasoning_content":null},"logprobs":null,"finish_reason":null}]}

📷 复现步骤

当使用deepseekR1输出时，大概率出现此类情况。
