The WebGPU API, allows you to use the GPU directly from JavaScript.

The WebGPU API is only accessible from within Durable Objects. The WebGPU API cannot be used from within Workers.

To use the WebGPU API in local development, enable the experimental and webgpu compatibility flags in the wrangler.toml configuration file of your Durable Object.

compatibility_flags = ["experimental", "webgpu"]
