Launching an Inpainting Neural Network Directly in the Browser

🎨 Launching an inpainting neural network directly in the browser

Developer Simon Willison used Claude Code to port the Moebius 0.2B model to run in the browser. The process involved converting from PyTorch to ONNX and using WebGPU via ONNX Runtime Web for acceleration.

🌍 Demonstrates the capabilities of "vibe coding": AI agents are capable of executing complex engineering chains—from research and weight conversion to deploying a web application.

👤 Now, complex neural networks for photo editing can be run locally in the browser without a powerful GPU or Python installation, making AI tools more accessible and private.
