OpenLLaMA is an effort from OpenLM Research to offer a non-gated version of LLaMa that can be used both for research and commercial applications. As of June 2023, the model is still training, with 3B, 7B, and 13B parameter models available.
Released alongside Koala, Vicuna is one of many descendants of the Meta LLaMA model trained on dialogue data collected from the ShareGPT website. According to the authors, Vicuna achieves more than 90% of ChatGPT's quality in user preference tests, while vastly outperforming Alpaca. As of May 2023, Vicuna seems to be the heir apparent of the instruct-finetuned LLaMA model family, though it is also restricted from commercial use.
