How fast can your phone spot a bird?

This page tests whether a species-recognition model (BioCLIP 2) can run entirely on your phone, and how fast. Nothing leaves your phone except the anonymous benchmark numbers below.

Send my results anonymously (device and browser, GPU, timings, accuracy; no photos, no location) Your name or phone model (optional, so I know whose result it is)

Nothing is sent until you run a test; each test says when its results were sent. The quick test downloads one model (200–600 MB): Wi-Fi recommended. You can delete it at the bottom of the page.
