Introduction
OpenChat is an open-source language model developed by a team from Tsinghua University and other collaborating institutions. It boasts a parameter count of just 7 billion, yet it achieves performance comparable to or surpassing industry-leading models like ChatGPT. Trained using the Conditioned Reinforcement Learning from Feedback (C-RLFT) method, OpenChat excels in tasks such as coding, question-answering, and language understanding. It is accessible for deployment on consumer-grade GPUs like the RTX 3090, making it an attractive option for those looking to leverage AI without the need for high-end hardware. OpenChat has also been recognized for its impact in the AI community, with over 4500 GitHub stars and a consistent presence in the top 5 on the HuggingFace global trends list.
