FAQ

What is the biggest AI model the iPhone 15 Pro can run?

Bonsai 27B (1-bit) (27B parameters) at Q1_0 — it needs 4.8GB of the ~5.2GB usable on the 8GB iPhone 15 Pro, at ~6.1 tokens/s.

How much of the iPhone 15 Pro's 8GB RAM can AI models actually use?

About 5.2GB. iOS caps a single app at roughly 65% of total RAM, so of the 8GB about 5.2GB is actually available to a model.

Can the iPhone 15 Pro run Llama 3.1 8B?

Not at Q4_K_M: it needs 6.3GB but the iPhone 15 Pro only has ~5.2GB usable. Try a smaller model like Qwen3 0.6B.

How fast is local AI on the iPhone 15 Pro?

The Apple A17 Pro has 51.2GB/s of memory bandwidth, which is what decode speed scales with. Small models like Ternary Bonsai 1.7B reach ~46.1 tokens/s; larger 7–14B models land in the single digits. Anything above ~8 tokens/s feels smooth for chat.

Which quantization should I use on the iPhone 15 Pro?

Q4_K_M is the size/quality sweet spot for most models. For example, Qwen3 0.6B at Q8_0 takes 1.3GB of memory here. Only drop to Q3 or IQ4 if a model just misses fitting; Q8 rarely pays off on 8GB of RAM.

Is 8GB of RAM enough for local AI?

29 of the 93 models we track fit on the iPhone 15 Pro — 25 run great and 4 run with compromises. 64 models (mostly 12B+) don't fit at their recommended quant.
