Nous Research released its first model, gpt4-x-vicuna-13b. This 13B model is based on Vicuna and was trained for 5 epochs on over 180k censor-free GPT-4 outputs. The datasets were contributed by Nous Research, Teknium, WizardLM, and GPT-4-LLM, with compute sponsored by Redmond AI. The team noted that the next step was to clean Vicuna to fully remove OpenAI censorship.
