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.
Open Pre-trained Transformer Language Models (OPT) is part of the family of open source models designed to replicate GPT-3, with similar decoder-only architecture. It has since been superseded by models such as LLaMA, GPT-J, and Pythia.
