# WebGPU

Last updated Sep 1, 2026|Copy as Markdown| [View as Markdown](https://sync-log-fields-2026-09-01.previews.developers.cloudflare.com/durable-objects/api/webgpu/index.md)| [Agent setup](https://sync-log-fields-2026-09-01.previews.developers.cloudflare.com/agent-setup/)

Caution

The WebGPU API is only available in local development. You cannot deploy Durable Objects to Cloudflare that rely on the WebGPU API. See [Workers AI](https://sync-log-fields-2026-09-01.previews.developers.cloudflare.com/workers-ai/) for information on running machine learning models on the GPUs in Cloudflare's global network.

The [WebGPU API ↗](https://developer.mozilla.org/en-US/docs/Web/API/WebGPU_API) allows you to use the GPU directly from JavaScript.

The WebGPU API is only accessible from within [Durable Objects](https://sync-log-fields-2026-09-01.previews.developers.cloudflare.com/durable-objects/). You cannot use the WebGPU API from within Workers.

To use the WebGPU API in local development, enable the `experimental` and `webgpu` [compatibility flags](https://sync-log-fields-2026-09-01.previews.developers.cloudflare.com/workers/configuration/compatibility-flags/) in the [Wrangler configuration file](https://sync-log-fields-2026-09-01.previews.developers.cloudflare.com/workers/wrangler/configuration/) of your Durable Object.

```plaintext
compatibility_flags = ["experimental", "webgpu"]
```

The following subset of the WebGPU API is available from within Durable Objects:
