## The human problem

Running models in a browser can reduce dependence on a remote server, but efficient GPU operations vary across devices and browsers.

## The prior constraint

Developers repeatedly implement and tune low-level GPU operations with limited shared test and benchmark infrastructure.

## AI’s actual role

The kernels perform the matrix and tensor operations used by browser-based model inference.

## The documented result

The developer preview contains 207 inspectable kernels plus tests, benchmarks, and Fleet tooling under Apache-2.0.

## Why it may matter

Shared low-level infrastructure can make local, inspectable AI more practical for small teams.

## Limitations

This is a developer preview.

One kernel's speed does not equal whole-application speed.

Local execution does not by itself prove that an application is offline or transfers no data.

## Unresolved questions

Which browsers and devices pass the full test suite?

How will regressions and numerical differences be tracked?

What end-to-end applications show meaningful benefit?
