Dr. Mandar Karhade, MD. PhD. wrote about the OpenChat model in the open source arena. The model uses novel methods to train large language models and has shown superior performance. The model is available under Apache 2.0 licensing on Hugging Face. The 13B version has been fine-tuned using LLaMA2–13B while the 7B version has been fine-tuned using Mistral-7B. The model weights are freely available and hosted on HuggingFace openchat/openchat-3.5–1210. You can read the full blog for free on Medium via Towards AI.
