Can I run Qwen2.5-VL 3B on iPhone 17?
Yes. Qwen2.5-VL 3B runs on iPhone 17 at Q4_K_M (~4.4 GB of ~4.5 GB usable).
Fits at Q4_K_M (~4.4 GB of ~4.5 GB usable) but with little headroom. Close background apps, and expect slow generation on a phone.
That figure is at a 4k context and moves about ±15% as context length changes. iPhone 17 leaves ~0.1 GB of headroom.

Weights are measured from GGUF files; KV cache and overhead are computed, so totals can vary ~15% with context and runtime. Any tok/s is a bandwidth estimate. See methodology.
