This repository is an awesome-list that catalogs open-source alternatives to ChatGPT, specifically targeting projects with fully open components: source code, training data, model weights, and instruction-finetuned language models. Projects are tagged as Bare (code only), Standard (with weights via API), Full (with weights and chat UI), or Complicated (semi-open). The list covers Instruct-finetuned LLMs, RLHF implementations, and related training tooling such as Alpaca, Open-Assistant, ChatGLM, and text generation web interfaces.
