Can I run DeepSeek R1 on iPhone 17 Pro?
No. DeepSeek R1 needs ~383.7 GB even at Q4_K_M, but iPhone 17 Pro only has ~8 GB usable.
Needs ~383.7 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 375.7 GB: DeepSeek R1 needs roughly 383.7 GB at Q4_K_M and iPhone 17 Pro leaves only about 8 GB usable for a model. No single tracked device has enough memory; DeepSeek R1 needs a multi-GPU or high-memory rig.

FAQ
Can iPhone 17 Pro run DeepSeek R1?
No. DeepSeek R1 needs ~383.7 GB even at Q4_K_M, but iPhone 17 Pro only has ~8 GB usable.
How much memory does DeepSeek R1 need?
iPhone 17 Pro does not have enough memory. At Q4_K_M the weights are ~376.65 GB; with KV cache and runtime overhead, budget ~383.7 GB at a 4k context. It is a Mixture-of-Experts model (671B total / 37B active), so all experts must stay in memory; memory tracks total params, not active params.
What is the best tool to run DeepSeek R1 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.
