Can I run Qwen2.5 Coder 1.5B on iPhone 17 Pro?
Yes. Qwen2.5 Coder 1.5B runs on iPhone 17 Pro at Q4_K_M (~2 GB of ~8 GB usable).
Runs at Q4_K_M using ~2 GB of ~8 GB usable. You have room for FP16 for higher quality.
That figure is at a 4k context and moves about ±15% as context length changes. iPhone 17 Pro leaves ~6 GB of headroom, room to step up to FP16 for higher quality.

Which quant fits
Running cost · estimate
- Power draw
- ~12 W
- Electricity / 1M tokens
- ~$0.01
- Pays for itself after
- ~2,243M tok
At ~$0.15/kWh and the estimated ~42 tok/s, a million generated tokens costs about $0.01 in electricity. Versus a hosted API at ~$0.5 per million tokens, the ~$1,099 iPhone 17 Pro pays for itself after roughly 2,243 million tokens, so local hardware is mostly a fixed cost, not a per-token one. TDP is the peak draw, so this is an upper bound. Assumptions.
How to run it
On iOS use Apple Foundation Models (Built into iOS 26, ~3B on-device model, zero download, fully private.).

FAQ
Can iPhone 17 Pro run Qwen2.5 Coder 1.5B?
Yes. Qwen2.5 Coder 1.5B runs on iPhone 17 Pro at Q4_K_M (~2 GB of ~8 GB usable).
How much memory does Qwen2.5 Coder 1.5B need?
iPhone 17 Pro has room to spare. At Q4_K_M the weights are ~0.92 GB; with KV cache and runtime overhead, budget ~2 GB at a 4k context.
What is the best tool to run Qwen2.5 Coder 1.5B on iOS?
On iPhone and iPad, Apple Foundation Models (Built into iOS 26, ~3B on-device model, zero download, fully private.) is the standard choice. Phones realistically run 1B-4B class models. Anything larger thermally throttles or OOMs.

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.
