 "github": "https://github.com/chenglou/handwired",
 "what": "Handwired turns regular JavaScript code into a neural net with no training: if-else, loops and state become matrix multiplication and reglu over floats. The result is exact and fully differentiable, and runs on JS or WebGPU.",
 "why": "2k stars, launched 10 days ago, talked about in 2 AI sources we track",
 "language": "TypeScript",
 "requirements": [
  "Bun to run the demos locally",
  "A browser for the live demos; WebGPU is optional"
 ],
 "audience_note": "JavaScript and ML developers curious about differentiable programs and GPU-parallel code.",
