When I try to use open-webui v0.5.16 with DeepSeek R1 model I can see as part of the thinking process that the model is receiving part of template as user message...

Thinking...
 
 

    Alright, so I'm trying to figure out what the user is asking for. The initial message was "begin of sentence >" and then the user wrote "Hey, man! Who are you?"  

    Hmm, okay. So the user started with "begin of sentence >", which seems like they were trying...

This puts the model of useless evaluations on why the user is sending this "begin of sentence" and it doesn't work as expected...

In the same time, trying the same question using curl, works just fine!

What could be the issue?
