Yeah, looks like it. Are you seeing any error in the dev console, or is the message just showing a "<" in the chat bubble? If it’s an error, could you share the full message?

chat bubble has not character likes '<',but in the control booth it show this message about error

[RimTalk] Exception in API request: There was an error deserializing the object of type RimTalk.Client.OpenAI.OpenAIResponse. Encountered an unexpected character '<' in JSON.

another error message is too long,its about the html file your mod used.
the error simply by "[RimTalk] Json deserialization failed for OpenAIResponse"

I’ve updated the code to better handle malformed JSON, so hopefully this resolves it. If it keeps happening, try switching to a different model.
