Can I run DeepSeek-V4-Pro on iPhone Air?
No. DeepSeek-V4-Pro needs ~965 GB even at Q4_K_M, but iPhone Air only has ~8 GB usable.
Needs ~965 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 957 GB: DeepSeek-V4-Pro needs roughly 965 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-V4-Pro needs a multi-GPU or high-memory rig.

FAQ
Can iPhone Air run DeepSeek-V4-Pro?
No. DeepSeek-V4-Pro needs ~965 GB even at Q4_K_M, but iPhone Air only has ~8 GB usable.
How much memory does DeepSeek-V4-Pro need?
iPhone Air does not have enough memory. At Q4_K_M the weights are ~954.58 GB; with KV cache and runtime overhead, budget ~965 GB at a 4k context. It is a Mixture-of-Experts model (1600B total / 49B active), so all experts must stay in memory; memory tracks total params, not active params.
What is the best tool to run DeepSeek-V4-Pro 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.
