AI Hybrid Inference: guard against unstable browser versions

Open erikeldridge opened this issue 6 months ago • 4 comments

Problem Statement

The implementation of the AI APIs can change while the API is stabilizing. This is impossible to guard against using normal feature detection because the feature exists, it just changes behavior.

Solution

Detect known stable versions of the API using the userAgentData API. This API has limited support, but it's simple to use and supported by Chrome and Edge, the two browsers implementing the Chromium AI API, so it's sufficient for now.
