Can I run Nemotron 3 Ultra 550B-A55B on Samsung Galaxy S26 Ultra (16GB, 1TB config)?
No. Nemotron 3 Ultra 550B-A55B needs ~341 GB even at Q4_K_M, but Samsung Galaxy S26 Ultra (16GB, 1TB config) only has ~12 GB usable.
Needs ~341 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 329 GB: Nemotron 3 Ultra 550B-A55B needs roughly 341 GB at Q4_K_M and Samsung Galaxy S26 Ultra (16GB, 1TB config) leaves only about 12 GB usable for a model. No single tracked device has enough memory; Nemotron 3 Ultra 550B-A55B needs a multi-GPU or high-memory rig.

FAQ
Can Samsung Galaxy S26 Ultra (16GB, 1TB config) run Nemotron 3 Ultra 550B-A55B?
No. Nemotron 3 Ultra 550B-A55B needs ~341 GB even at Q4_K_M, but Samsung Galaxy S26 Ultra (16GB, 1TB config) only has ~12 GB usable.
How much memory does Nemotron 3 Ultra 550B-A55B need?
Samsung Galaxy S26 Ultra (16GB, 1TB config) does not have enough memory. At Q4_K_M the weights are ~334.55 GB; with KV cache and runtime overhead, budget ~341 GB at a 4k context. It is a Mixture-of-Experts model (550B total / 55B active), so all experts must stay in memory; memory tracks total params, not active params.
What is the best tool to run Nemotron 3 Ultra 550B-A55B 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.
