得让他把 stream 拿出来，然后加个单测

You have to ask him to take out the stream and add a single test

[arvinxx]

明确了，#3983 (comment) 。不太想解，感觉这是 new api 对齐 OpenAI 规范的问题

[abix5]

Hey guys, can we already merge this pull request and fix the bug?

[hezhijie0327]

@abix5 can share then steam here? From your screenshot seems not the same as that issue

oh sorry, seems is the same...

[abix5]

Yes, of course, here's the stream. None of the models outputs the result to the chat

[hezhijie0327]

Your API is from OpenAI or other provider?

[abix5]

OpenAI, however, uses a corporate proxy to it. But the requests are not modified.

[hezhijie0327]

Have you try current latest version? From stream seems no issue, basicly same as mine, and it's working

Found the cause, catch by if (item.delta?.tool_calls) {

[hezhijie0327]

@abix5 can build on local and have a test?
