WebGPU Browser AI: Run LLMs Client-Side, No Backend

WebGPU transforms browser-based AI by enabling direct GPU compute access, eliminating expensive cloud inference costs. Unlike WebGL's graphics-pipeline workarounds, WebGPU provides purpose-built compute shaders delivering 3-8x performance improvements. Libraries like Transformers.js and ONNX Runtime Web already support WebGPU backends, enabling quantized models up to 3B parameters to run locally with zero server costs and complete privacy.
