[Atomic-Chat](https://atomic.chat) reports 1.4k GitHub stars, 157 forks, and 36 open issues, last pushed Aug 24, 2026. [openinfer](https://pegainfer.org/) has 657 stars, 103 forks, and 102 open issues, last pushed Aug 25, 2026. Figures are from public GitHub metadata via [Atomic-Chat's repository](https://github.com/AtomicBot-ai/Atomic-Chat) and [openinfer's repository](https://github.com/openinfer-project/openinfer). | | [Atomic-Chat](/tools/atomicbot-ai-atomic-chat.md) | [openinfer](/tools/openinfer-project-openinfer.md) | | --- | --- | --- | | Tagline | Local AI app and inference engine for agents | Pure Rust CUDA LLM inference engine serving multiple models including Qwen3 and Kimi-K2 | | Stars | 1,363 | 657 | | Forks | 157 | 103 | | Open issues | 36 | 102 | | Language | TypeScript | Rust | | Adopt for | Atomic-Chat is a local AI app and inference engine for agents that runs open-weight LLMs privately offline. | high-performance GPU-based inference engine for Rust developers targeting Qwen3 and Kimi-K2 using pure CUDA kernels | | Persona | - | - | | Runtime | - | - | | License | Other | Apache-2.0 | | Categories | Developer Tools, Inference & Serving | Inference & Serving | ## Trust and health _Sourced signals - not a safety guarantee.
