Can I run Hunyuan-A13B-Instruct on iPhone 17?
No. Hunyuan-A13B-Instruct needs ~48.3 GB even at Q4_K_M, but iPhone 17 only has ~4.5 GB usable.
Needs ~48.3 GB even at Q4_K_M, but only ~4.5 GB is usable.
That figure is at a 4k context and moves about ±15% as context length changes.
The gap is about 43.8 GB: Hunyuan-A13B-Instruct needs roughly 48.3 GB at Q4_K_M and iPhone 17 leaves only about 4.5 GB usable for a model. The lightest tracked hardware that runs Hunyuan-A13B-Instruct is the Apple M4 Max (128GB) at 128 GB. See Hunyuan-A13B-Instruct on Apple M4 Max (128GB).

FAQ
Can iPhone 17 run Hunyuan-A13B-Instruct?
No. Hunyuan-A13B-Instruct needs ~48.3 GB even at Q4_K_M, but iPhone 17 only has ~4.5 GB usable.
How much memory does Hunyuan-A13B-Instruct need?
iPhone 17 does not have enough memory. At Q4_K_M the weights are ~45.43 GB; with KV cache and runtime overhead, budget ~48.3 GB at a 4k context. It is a Mixture-of-Experts model (80B total / 13B active), so all experts must stay in memory; memory tracks total params, not active params.
What is the best tool to run Hunyuan-A13B-Instruct 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.
