Is this compatible with the deepseek-r1 ollama output as well? It uses <think> </think> as markers (even if that's not standard yet).

[michnovka]

Do we need to enable sth special to see the collapsible UI?

[danny-avila]

looks like your frontend is cached, you need to clear cache/localStorage

no, didn't know it did this. I can add that soon

@christiaangoossens Which model/tag are you using with Ollama?

I'm getting the same issue. I've tried clearing the cache/localStorage in my Chrome browser (Version 131.0.6778.265).

In the meantime, is there a flag or configuration we can set to force the UI to use this new feature?

[danny-avila]

Hi @peterhoang I see the issue now, I'll be patching it shortly

https://ollama.com/library/deepseek-r1, afaik all of them use <think> syntax.

Got it the mentioned issues are now resolved here: #5456

[xhejtman]

we are almost there with ollama deepseek-r1 (via preset)

[danny-avila]

@xhejtman I recommend using a different title model, since you'll get thoughts in those title generations. I can maybe think of a way to remove them, though

thanks. However, as of the latest commit, DS R1 with ollama (no openrouter), it does not display thoughts in the main chat window at all, only in sidebar as you noticed.

[danny-avila]

@xhejtman it could be no thoughts were generated, I've noticed this is the case when you just say "hi."

Either this or you need to update Ollama (I thought the same thing until I got the latest version)

[xhejtman]

yes, you are right sorry, it is ok, I was confused by tag in the left sidebar supposing that it actualy returned as it is displayed.
