[ChatAbstractions](https://github.com/andrewnguonly/ChatAbstractions) reports 84 GitHub stars, 5 forks, and 4 open issues, last pushed Jan 29, 2024. [OpenChat](https://open.cx) has 5.2k stars, 644 forks, and 37 open issues, last pushed Feb 27, 2024.

Prefer an active alternative unless you maintain a private fork or need a frozen dependency. - Evaluation & Observability: Defer heavyweight eval infra only until you have real traffic - never skip it once users depend on answers. - Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic. ## Common questions ### What is the difference between ChatAbstractions and OpenChat?
