OpenAssistant is a project organized by LAION with aim of providing an open source alternative to ChatGPT. Its primary effort is to collected instruct examples to then tune existing LLMs. The first major release is available as part of Hugging Face's HuggingChat.
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.
