Llama 3.1 Family — local AI model by Meta

Written by Jakub Rusinowski · Last updated

Superseded model. Llama 3.1 Family has been superseded by Llama 4. This page is kept for reference; the newer family is a better starting point. View Llama 4 →

The default first install and still the most-pulled model on Ollama by a wide margin. Llama 3.1 is legacy-but-safe rather than current-best: newer small-dense models beat it on coding and reasoning at the same size, but nothing matches it for tooling support, community familiarity, and being the model every guide assumes. Keep it as the smoke test, not the recommendation.

Variants

The smallest Llama 3.1 Family variant needs about 6 GB of VRAM at Q4_K_M — quantized weights plus framework overhead, before any KV cache.

Llama 3.1 Family — frequently asked questions

How much VRAM does Llama 3.1 Family need?

Llama 3.1 Family needs about 6 GB VRAM at Q4_K_M quantization for its smallest variant. Variants: Llama 3.1 8B Instruct (6 GB, Q4_K_M). On Apple Silicon, unified memory counts toward this requirement.

Can I run Llama 3.1 Family on an RTX 4090 (24 GB)?

Yes — Llama 3.1 Family runs on an RTX 4090 (24 GB) and other 24 GB cards such as the RTX 3090. Smaller variants also fit comfortably on 8–16 GB GPUs at Q4_K_M.

What quantization should I use for Llama 3.1 Family?

Q4_K_M is the best balance of quality and VRAM for Llama 3.1 Family in most cases. Choose Q8_0 for near-lossless quality if you have spare VRAM, or smaller quants (Q3/Q2) only when memory is tight.

How do I run Llama 3.1 Family with Ollama?

Install Ollama, then run: ollama run llama3.1. This downloads Llama 3.1 Family and starts a local, OpenAI-compatible endpoint — no internet connection is needed after the initial download.
