It provides an OpenAI API-compatible interface and supports GGUF natively. [aikit](https://kaito-project.github.io/aikit/) reports 537 GitHub stars, 57 forks, and 40 open issues, last pushed Aug 24, 2026. [shimmy](https://github.com/Michael-A-Kuykendall/shimmy) has 5.8k stars, 559 forks, and 12 open issues, last pushed Aug 20, 2026.
