How are you running AnythingLLM?

Docker (remote machine)

What happened?

Hi!

I'm having an issue using OpenRouter as LLM provider, only with certain models.
Once the prompt is sent, any response is given and the only thing I get is an empty sentence.
In the example image i was using Perplexity Sonar Search Pro, but the same happens with other models, such as GPT 5.1. These work on the OpenRouter webui. The models I can use without any problem in AnythingLLM are, for example, Claude Opus 4.5 or GPT 4.1-mini.

Thanks in advance

Are there known steps to reproduce?

Use OpenRouter as provider and choose one of the models mentioned above

@TheCass1 I was unable to reproduce the bug you are experiencing. I was able to get responses from all the models you mentioned. To debug this further, can you please check for any logs that might be in your console (both from server and frontend) when you send a prompt and share them?
