Run Gemma 4 on iPhone 14 with Google AI Edge Gallery

iPhone 14 is the oldest iPhone with confirmed real-world Gemma 4 benchmarks. A Hacker News user reported running Gemma 4 E2B at 12 tokens per second on the A15 Bionic chip with 6 GB of RAM in April 2026 — slow compared to newer iPhones, but still usable for short prompts and casual chat. The older silicon stays cool under load, which is a nice side effect when newer A18 Pro devices report thermal throttling. If you own an iPhone 14 and are not upgrading soon, Google AI Edge Gallery still gives you a real on-device AI experience.

Verdict

Recommended: Gemma 4 E2B

iPhone 14 is the slowest supported iPhone for Gemma 4, but it works. ~12 tok/s is enough for casual use, and the older chip stays cool.

Frequently Asked Questions

Can iPhone 14 actually run Gemma 4?+

Yes. A Hacker News user confirmed Gemma 4 E2B running at roughly 12 tokens per second on iPhone 14 in April 2026 ([HN thread](https://news.ycombinator.com/item?id=47652561)). That is slow but conversationally usable. The A15 Bionic and 6 GB of RAM are the minimum viable spec.

How fast is Gemma 4 on iPhone 14?+

Measured at ~12 tokens per second for Gemma 4 E2B by a Hacker News user in April 2026. That is roughly 40% the speed of an iPhone 16 Pro on the same model. The user reported the device stayed at a normal temperature, which is one upside of older silicon.

Is iPhone 14 too old for local AI in 2026?+

No — Gemma 4 E2B runs and is usable. But if AI is a major reason you use your phone, the gap to a current iPhone is large: iPhone 16 Pro is roughly 2.5x faster at the same task. For occasional offline AI use, iPhone 14 is fine.

Does iPhone 14 support Apple Intelligence?+

No. Apple Intelligence requires 8 GB of RAM and is limited to iPhone 15 Pro, iPhone 16 series, and newer devices. iPhone 14 has 6 GB of RAM and is not supported. Google AI Edge Gallery is therefore your main path to on-device AI on this phone.
