FAQ

What is the biggest AI model the Galaxy S25 FE can run?

Bonsai 27B (1-bit) (27B parameters) at Q1_0 — it needs 4.8GB of the ~6GB usable on the 8GB Galaxy S25 FE and runs at ~8 tokens/s.

How much of the Galaxy S25 FE's 8GB RAM can AI models actually use?

About 6GB. Android keeps roughly 2–4GB for the system and resident apps, so of the 8GB about 6GB is actually available to a model.

Can the Galaxy S25 FE run Llama 3.1 8B?

Not at Q4_K_M: it needs 6.3GB but the Galaxy S25 FE only has ~6GB usable. Try a smaller model like Qwen3 0.6B.

How fast is local AI on the Galaxy S25 FE?

The Samsung Exynos 2400 has 67.2GB/s of memory bandwidth, which is what decode speed scales with. Small models like Ternary Bonsai 1.7B reach ~60.5 tokens/s; larger 7–14B models land in the single digits. Anything above ~8 tokens/s feels smooth for chat.

Which quantization should I use on the Galaxy S25 FE?

Q4_K_M is the size/quality sweet spot for most models. For example, Qwen3 0.6B at Q8_0 takes 1.3GB of memory here. Only drop to Q3 or IQ4 if a model just misses fitting; Q8 rarely pays off on 8GB of RAM.

Is 8GB of RAM enough for local AI?

30 of the 93 models we track fit on the Galaxy S25 FE — 29 run great and 1 run with compromises. 63 models (mostly 12B+) don't fit at their recommended quant.
