Hardwired

Hardwired is a tool that turns regular JavaScript code into an exact, differentiable neural net.

Handwired turns regular JavaScript code into a neural net without requiring training. It is exact, fully differentiable, and runnable in a browser without a GPU. The software converts JavaScript functions like regex matching, JSON parsing, and highlighting into WebGPU kernels for massive parallelism. Users can unfreeze compiled program weights and train them in real time. It enables projects like a small desktop rendered to the regular DOM with animations and drag inputs.
