Have you tried to update the system messages of the agent? Different models should have different system messages. The default one is tailored to OpenAI's models.

Great! I figured it out. Thanks for your help!
Btw, it shows the response with a single or a couple words on the line instead of a full sentence. Plus, why does it show the history instead of showing just a response?
Please take a look at this:

It is showing a chat history because under-the-hood a message from the human user triggers a two-agent chat workflow, and the summary of the two-agent chat conversation is the final response to the human user.

@jackgerrits @victordibia This issue involves LMStudio and AGS.

@Giova200 , thanks for mentioning this.
I think this is related to #2050.
Essentially, some models/endpoints require max_tokens to be explicitly which seems to be the case with lmstudio.
I am working on exposing that parameter correctly in the Agent UI. In the mean time, consider the work around in the #2050 (setting the default max tokens directly in code)
