Field notes
Barx describes treating memory as a cache for model experts rather than a home for the entire model. Its stated expert budget is 2–4 GB, sized to the machine, and includes the engine, its workers, and model pages in the file cache. The page also says its kernels reproduce reference results bit for bit and that existing Ollama-compatible apps can connect unchanged.
