Can I run GLM-5.2 on iPad Pro M4 (16GB, 1TB/2TB config)?
No. GLM-5.2 needs ~473.1 GB even at Q4_K_M, but iPad Pro M4 (16GB, 1TB/2TB config) only has ~12 GB usable.
Needs ~473.1 GB even at Q4_K_M, but only ~12 GB is usable.
That figure is at a 4k context and moves about ±15% as context length changes.
The gap is about 461.1 GB: GLM-5.2 needs roughly 473.1 GB at Q4_K_M and iPad Pro M4 (16GB, 1TB/2TB config) leaves only about 12 GB usable for a model. No single tracked device has enough memory; GLM-5.2 needs a multi-GPU or high-memory rig.

FAQ
Can iPad Pro M4 (16GB, 1TB/2TB config) run GLM-5.2?
No. GLM-5.2 needs ~473.1 GB even at Q4_K_M, but iPad Pro M4 (16GB, 1TB/2TB config) only has ~12 GB usable.
How much memory does GLM-5.2 need?
iPad Pro M4 (16GB, 1TB/2TB config) does not have enough memory. At Q4_K_M the weights are ~465.83 GB; with KV cache and runtime overhead, budget ~473.1 GB at a 4k context. It is a Mixture-of-Experts model (744B total / 40B active), so all experts must stay in memory; memory tracks total params, not active params.
What is the best tool to run GLM-5.2 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.
