I’m mention a AI character I created in a topic on the forum, but I’m getting a 500 error message. (I turn on the mention setting when creating the character.) Example console error:

logs error message:

I guess it’s my fault. This setting needs to be selected if topic mentions will be used: Default Language Model

I made a mention to test it, still waiting for an answer. :slight_smile:

edit:
When I got an error like this, I changed the model and it was fixed. (gpt-3.5-turbo):
Model open_ai:gpt-3.5-turbo-16k not found for persona Motivational_Coach
