Can I run SmolLM3 3B on Samsung Galaxy S24 Ultra?

Compatibility verdict VRAM threshold engine
Yes, it runs usable speed ~22 tok/s est.

Yes. SmolLM3 3B runs on Samsung Galaxy S24 Ultra at Q4_K_M (~3 GB of ~8.5 GB usable).

Needs ~3 GB Device usable ~8.5 GB

Runs at Q4_K_M using ~3 GB of ~8.5 GB usable. You have room for FP16 for higher quality.

That figure is at a 4k context and moves about ±15% as context length changes. Samsung Galaxy S24 Ultra leaves ~5.5 GB of headroom, room to step up to FP16 for higher quality.

~2,706M tok

At ~$0.15/kWh and the estimated ~22 tok/s, a million generated tokens costs about $0.02 in electricity. Versus a hosted API at ~$0.5 per million tokens, the ~$1,299 Samsung Galaxy S24 Ultra pays for itself after roughly 2,706 million tokens, so local hardware is mostly a fixed cost, not a per-token one. TDP is the peak draw, so this is an upper bound. Assumptions.

How to run it

On Android use PocketPal AI (Polished app, download GGUF and run offline.).

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.
