FAQ

What is the biggest AI model the vivo S2 can run?

Bonsai 27B (1-bit) (27B parameters) at Q1_0 — it needs 4.8GB of the ~6GB usable on the 8GB vivo S2, at ~2 tokens/s.

How much of the vivo S2'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 vivo S2 run Llama 3.1 8B?

Not at Q4_K_M: it needs 6.3GB but the vivo S2 only has ~6GB usable. Try a smaller model like Ternary Bonsai 1.7B.

How fast is local AI on the vivo S2?

The Dimensity 7360-Turbo has 17.1GB/s of memory bandwidth, which is what decode speed scales with. Small models like Ternary Bonsai 1.7B reach ~15.4 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 vivo S2?

Q4_K_M is the size/quality sweet spot for most models. For example, Ternary Bonsai 1.7B at Q2_0 takes 1.2GB 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 89 models we track fit on the vivo S2 — 5 run great and 25 run with compromises. 59 models (mostly 12B+) don't fit at their recommended quant.
