Can I run ERNIE 4.5 21B-A3B on Samsung Galaxy S24 Ultra?
No. ERNIE 4.5 21B-A3B needs ~14.3 GB even at Q4_K_M, but Samsung Galaxy S24 Ultra only has ~8.5 GB usable.
Needs ~14.3 GB even at Q4_K_M, but only ~8.5 GB is usable.
That figure is at a 4k context and moves about ±15% as context length changes.
The gap is about 5.8 GB: ERNIE 4.5 21B-A3B needs roughly 14.3 GB at Q4_K_M and Samsung Galaxy S24 Ultra leaves only about 8.5 GB usable for a model. The lightest tracked hardware that runs ERNIE 4.5 21B-A3B is the Nvidia GeForce RTX 4060 Ti (16GB) at 16 GB. See ERNIE 4.5 21B-A3B on Nvidia GeForce RTX 4060 Ti (16GB).

FAQ
Can Samsung Galaxy S24 Ultra run ERNIE 4.5 21B-A3B?
No. ERNIE 4.5 21B-A3B needs ~14.3 GB even at Q4_K_M, but Samsung Galaxy S24 Ultra only has ~8.5 GB usable.
How much memory does ERNIE 4.5 21B-A3B need?
Samsung Galaxy S24 Ultra does not have enough memory. At Q4_K_M the weights are ~12.42 GB; with KV cache and runtime overhead, budget ~14.3 GB at a 4k context. It is a Mixture-of-Experts model (21B total / 3B active), so all experts must stay in memory; memory tracks total params, not active params.
What is the best tool to run ERNIE 4.5 21B-A3B on Android?
On Android, PocketPal AI (Polished app, download GGUF and run offline.) is the go-to option. NPU acceleration is limited and chip-specific; most apps run on CPU. Expect 1B-4B class.

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.
