Llama 3.1 Tulu 3 8B — Hardware Requirements & GPU Compatibility

Chat

Llama-3.1-Tulu-3-8B is Allen Institute for AI's fully open instruction-following model, built on Meta's Llama 3.1 8B base through a public pipeline of supervised fine-tuning, direct preference optimization, and a final reinforcement learning stage with verifiable rewards (RLVR). It is tuned for chat as well as harder tasks like math, GSM8K, and instruction-following (IFEval), with all training data, code, and recipes released openly as part of the Tulu 3 project. Its 8B size lets it run on a single consumer GPU. Context length is 131,072 tokens. It is released under the Llama 3.1 Community License Agreement, which restricts use above 700 million monthly active users and imposes Meta's acceptable-use policy. It was published in November 2024, alongside a 70B and later a 405B sibling trained the same way.

Frequently Asked Questions

How much VRAM does Llama 3.1 Tulu 3 8B need?

Llama 3.1 Tulu 3 8B requires 5.4 GB of VRAM at Q4_K_M, or 16.6 GB at BF16. Full 131K context adds up to 16.9 GB (22.3 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 8.0B × 4.8 bits ÷ 8 = 4.8 GB

KV Cache + Overhead ≈ 0.6 GB (at 2K context + ~0.3 GB framework)

Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.

KV Cache + Overhead ≈ 17.5 GB (at full 131K context)
