Wasi: WebGPU – A Proposed WebAssembly System Interface API

The wasi:webgpu proposal seeks to bring GPU access to WebAssembly through a new WebAssembly System Interface API, enabling portable and secure GPU computing for applications including server-side graphics streaming, scientific computing, AI/ML inference, and data processing. Currently in Phase 2, the proposal is based on the official WebGPU specification but deviates where necessary to accommodate non-web environments rather than JavaScript-dependent assumptions. The API documentation and detailed design choices are available in the proposal's technical specifications, with stakeholder feedback still being gathered before advancing to Phase 3.
