What is the WebGPU Browser AI Test?

It is a private browser-side readiness test that checks WebGPU availability, adapter limits, compute timing, and device signals to recommend a practical starting point for local AI.

Can my browser run a local LLM?

If WebGPU is available and the readiness score is healthy, the page recommends a local LLM size to try first before downloading larger models.

Does the WebGPU AI test upload my hardware details?

No. The test runs locally in the browser and does not upload prompts, hardware details, or benchmark results to WebGPU.ai.

Private browser test

WebGPU Browser AI Test

Check whether your browser can run local LLMs, JAX, and WebGPU AI tools before downloading a model.

AI readiness score

Testing WebGPU support, adapter limits, and compute performance.

Testing

Recommended first download

A practical model choice based on the browser signals this page can measure.

Testing local AI fit

Benchmark in progress

The profiler is checking your GPU adapter, memory signals, and WebGPU compute path.

Confidence: Pending. This test stays on your device and does not upload prompts, hardware details, or benchmark results.

Why this helps

Model downloads are large. This gives you a browser-specific starting point first.

WebGPU support can vary by browser, operating system, GPU driver, and privacy settings.

The score combines adapter limits, local compute timing, CPU threads, and available memory signals.

Matrix math, gradients, and notebook-style experiments should run locally in this browser.

Text tools

Start small

Compact text tasks are the safest starting point on this setup.

Vision and multimodal demos

Start small

Prefer small image models and short sessions until you know the browser stays responsive.

What is WebGPU?

WebGPU lets websites use modern GPU hardware for compute and graphics, which helps local tools stay responsive.

Can my browser run local chat?

If WebGPU is available and the score is healthy, start with the recommended compact model before trying larger downloads.

Is this a GPU benchmark?

It is a lightweight readiness check, not a full hardware benchmark or a guarantee of model speed.
