# Awesome Open Source AI Alternatives 🚀
> A curated list of open-source alternatives to proprietary AI tools (OpenAI, Anthropic, Google, etc.)
> Last updated: July 2026
This list focuses on practical **ChatGPT alternatives**, self-hostable AI, open model weights, and open-source tools. Check each project's own license before using it commercially; “open weights” is not always the same as an OSI-approved open-source license.
