Deepseek R1 issue

Bug Reports
1

Hello,

I enabled deepseek r1 model with openAI api key.

It could work when the conversation is short, but when the conversation gets longer, I would always get this response error:

deepseek-reasoner does not support successive user or assistant messages (messages[1] and messages[2] in your input). You should interleave the user/assistant messages in the message sequence.

Looks like cursor somehow split one response into two and broke the conversation ? Why can’t we insert a dummy message between the two?

I’m not sure if this is a bug, or the deepseek doesn’t strictly follow openai’s api.

But I would very appreciate if you can take a deeper look into it.

Thank you!
Jack

Got another issue.
Sometimes it raise error:

The first message (except the system message) of deepseek-reasoner must be a user message, but an assistant message detected.

I’m stuck here too. If I don’t add any file, the answer is fine. But if I add add any file, I got the above error message. Please fix it Cursor team.
