Psyfighter v2 13B

koboldai/psyfighter-13b-2

Created Dec 8, 20234,096 context

The v2 of Psyfighter - a merged model created by the KoboldAI community members Jeb Carter and TwistedShadows, made possible thanks to the KoboldAI merge request service.

The intent was to add medical data to supplement the model's fictional ability with more details on anatomy and mental states. This model should not be used for medical advice or therapy because of its high likelihood of pulling in fictional data.

It's a merge between:

  • KoboldAI/LLaMA2-13B-Tiefighter
  • Doctor-Shotgun/cat-v1.0-13b
  • Doctor-Shotgun/llama-2-13b-chat-limarp-v2-merged.
