About OpenChat
- OpenChat is an innovative library of open-source language models, fine-tuned with C-RLFT - a strategy inspired by offline reinforcement learning.
- Our models learn from mixed-quality data without preference labels, delivering exceptional performance on par with
ChatGPT, even with a7Bmodel which can be run on a consumer GPU (e.g. RTX 3090). - Despite our simple approach, we are committed to developing a high-performance, commercially viable, open-source large language model, and we continue to make significant strides toward this vision.
