How fast does Gemma 3 12B (Vision) run on iPhone?

Gemma 3 12B (Vision) hasn't been measured on the reference iPhone yet, so there's no speed figure for it here.

You can measure it on your own phone with Model Benchmark in the app. It runs the same protocol as the numbers on the benchmarks page.

How much memory and storage does Gemma 3 12B (Vision) need?

The catalog budgets 8.4 GB of RAM and 7.5 GB of storage for the 4bit build of Gemma 3 12B (Vision).

Its backend copies weights into the app's memory, so the app checks it against the per-app limit iOS enforces. On a 6 GB iPhone that limit is much lower than 6 GB.

Which iPhones can run Gemma 3 12B (Vision)?

Gemma 3 12B (Vision) needs more memory than iPhones give a single app today, so it's meant for iPads with more RAM.
