Can I run Qwen3-Coder 30B-A3B on iPhone 17 Pro?
No. Qwen3-Coder 30B-A3B needs ~19.4 GB even at Q4_K_M, but iPhone 17 Pro only has ~8 GB usable.
Needs ~19.4 GB even at Q4_K_M, but only ~8 GB is usable.
That figure is at a 4k context and moves about ±15% as context length changes.
The gap is about 11.4 GB: Qwen3-Coder 30B-A3B needs roughly 19.4 GB at Q4_K_M and iPhone 17 Pro leaves only about 8 GB usable for a model. The lightest tracked hardware that runs Qwen3-Coder 30B-A3B is the Nvidia GeForce RTX 4090 (24GB) at 24 GB. See Qwen3-Coder 30B-A3B on Nvidia GeForce RTX 4090 (24GB).

FAQ
Can iPhone 17 Pro run Qwen3-Coder 30B-A3B?
No. Qwen3-Coder 30B-A3B needs ~19.4 GB even at Q4_K_M, but iPhone 17 Pro only has ~8 GB usable.
How much memory does Qwen3-Coder 30B-A3B need?
iPhone 17 Pro does not have enough memory. At Q4_K_M the weights are ~17.28 GB; with KV cache and runtime overhead, budget ~19.4 GB at a 4k context. It is a Mixture-of-Experts model (30.5B total / 3.3B active), so all experts must stay in memory; memory tracks total params, not active params.
What is the best tool to run Qwen3-Coder 30B-A3B 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.
