The ideal mobile AI model. Outperforms many older 7B models while running on smartphones with 6GB+ RAM. Near-instant responses on modern phones.

Llama 3.2 3B Instruct needs about 3 GB of VRAM at Q4_K_M — quantized weights plus framework overhead, before any KV cache. On Apple Silicon that figure comes out of unified memory.

VRAM and Speed by Quantization

Modelled on a reference NVIDIA RTX 4090 (24 GB), at 8K context. Speed figures are ESTIMATES from the memory-bandwidth roofline described on the methodology page, not benchmarks we ran — rows marked measured come from published or reader-submitted runs. VRAM here includes the KV cache, so it reads higher than the headline figure above, which does not.

Llama 3.2 3B Instruct — Frequently Asked Questions

How much VRAM does Llama 3.2 3B Instruct need?
About 3 GB at Q4_K_M — quantized weights plus framework overhead, before any KV cache. The cache grows with context length and is added on top; the table above folds it in. Apple Silicon counts unified memory toward the same figure.
Does Llama 3.2 3B Instruct run on an RTX 4090 (24 GB)?
Yes. Llama 3.2 3B Instruct needs about 3 GB at Q4_K_M, inside a 24 GB card, at an estimated 184 tokens/sec.
How do I run Llama 3.2 3B Instruct locally?
Install Ollama and run `ollama run llama3.2:3b`. That pulls the weights and starts a local OpenAI-compatible endpoint; after the download nothing leaves the machine.
What other sizes does Llama 3.2 Family come in?
Llama 3.2 1B Instruct (2 GB), Llama 3.2 3B Instruct (3 GB), Llama 3.2 11B Vision Instruct (7 GB), Llama 3.2 90B Vision Instruct (54 GB). Every size shares the family's training and licence; the larger ones score higher and need proportionally more memory.
