Was it with a recent model, like Qwen 3 or Gemma 3? I haven't updated the game, but the plugin it uses had some major updates that might help with crashes from newer models.
Ah darn. I'll try to update the game later in the week and see if that helps. What hardware and OS are you using? I've tested only on Windows 10 with a 3060 Ti, so I'm not sure if there are problems with other setups.
Processor Intel(R) Core(TM) i9-14900K 3.20 GHz with windows 10. It should be able to handle this application, I've run some local AI Kobold for AI Roguelite on Steam with it.
