About RWKV-Runner
RWKV Runner is a management and startup tool for RWKV, an open source large language model that is available for commercial use. It ships as a lightweight executable of only a few megabytes and automates the work of getting a model running, so that the user does not have to assemble the runtime, dependencies, and serving stack by hand. The project is written in TypeScript and built with Wails, and it is distributed under the MIT license from the josStorer repository. It lives in the RWKV ecosystem and in the broader local inference tooling space, with a companion site at rwkv.com.
