Run Gemma 4 on iPhone 17 with Google AI Edge Gallery

The standard iPhone 17 brings Apple's A19 chip and 8 GB of RAM to a non-Pro device for the first time. That combination handles Google Gemma 4 E2B effortlessly through Google AI Edge Gallery, with estimated speeds north of 35 tokens per second. The larger E4B model technically runs but eats most of your memory budget — close other apps before loading it. For most users, E2B at full speed is the right pick.

Verdict

Recommended: Gemma 4 E2B

iPhone 17 with 8 GB RAM is the value sweet spot for on-device Gemma. E2B runs fast and cool; E4B works if you really need it.

Frequently Asked Questions

Does iPhone 17 support Google AI Edge Gallery?+

Yes. iPhone 17 runs iOS 18+ and meets the Google AI Edge Gallery requirement of iOS 17.0 or later. Both Gemma 4 E2B and E4B variants are supported, though E2B is the recommended pick for the 8 GB RAM tier.

How fast is Gemma 4 E2B on iPhone 17?+

Estimated at roughly 35 tokens per second based on the A19's improvements over the A18 (which measured ~30 tok/s on iPhone 16 Pro per Hacker News user reports). Real-world numbers will vary with thermal state and battery level.

Should I pick iPhone 17 or iPhone 17 Pro for AI?+

iPhone 17 Pro with 12 GB RAM is the only model where Gemma 4 E4B runs comfortably. If you want the largest local model, get the Pro. If E2B is enough — and for most chat, translation, and image Q&A tasks it is — the standard iPhone 17 is the better value.

Can I run multiple AI models simultaneously on iPhone 17?+

Not really. The Google AI Edge Gallery app loads one model at a time into memory. Switching between Gemma 4 E2B and E4B requires unloading and reloading, which takes a few seconds. With 8 GB RAM, holding two models in memory at once is not practical.
