Compatibility verdict VRAM threshold engine
No, not enough memory would not load

No. Nemotron Cascade 2 30B-A3B needs ~25.1 GB even at Q4_K_M, but Samsung Galaxy S24 Ultra only has ~8.5 GB usable.

Needs ~25.1 GB Device usable ~8.5 GB

Needs ~25.1 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 16.6 GB: Nemotron Cascade 2 30B-A3B needs roughly 25.1 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 Nemotron Cascade 2 30B-A3B is the Nvidia GeForce RTX 5090 (32GB) at 32 GB. See Nemotron Cascade 2 30B-A3B on Nvidia GeForce RTX 5090 (32GB).

FAQ

Can Samsung Galaxy S24 Ultra run Nemotron Cascade 2 30B-A3B?

No. Nemotron Cascade 2 30B-A3B needs ~25.1 GB even at Q4_K_M, but Samsung Galaxy S24 Ultra only has ~8.5 GB usable.

How much memory does Nemotron Cascade 2 30B-A3B need?

Samsung Galaxy S24 Ultra does not have enough memory. At Q4_K_M the weights are ~23.03 GB; with KV cache and runtime overhead, budget ~25.1 GB at a 4k context. It is a Mixture-of-Experts model (30B total / 3B active), so all experts must stay in memory; memory tracks total params, not active params.

What is the best tool to run Nemotron Cascade 2 30B-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.

Sources

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.
