Can I run DeepSeek-R1-0528 on iPhone Air?
No. DeepSeek-R1-0528 needs ~384.1 GB even at Q4_K_M, but iPhone Air only has ~8 GB usable.
Needs ~384.1 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 376.1 GB: DeepSeek-R1-0528 needs roughly 384.1 GB at Q4_K_M and iPhone Air leaves only about 8 GB usable for a model. No single tracked device has enough memory; DeepSeek-R1-0528 needs a multi-GPU or high-memory rig.

FAQ
Can iPhone Air run DeepSeek-R1-0528?
No. DeepSeek-R1-0528 needs ~384.1 GB even at Q4_K_M, but iPhone Air only has ~8 GB usable.
How much memory does DeepSeek-R1-0528 need?
iPhone Air does not have enough memory. At Q4_K_M the weights are ~377.13 GB; with KV cache and runtime overhead, budget ~384.1 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-R1-0528 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.
