Llama 3.1 Tulu 3 70B — Hardware Requirements & GPU Compatibility
ChatLlama-3.1-Tulu-3-70B is Allen Institute for AI's 70.6-billion-parameter instruction-following chat model, built by post-training Meta's Llama-3.1-70B base through a fully open pipeline of supervised fine-tuning, direct preference optimization, and a final reinforcement-learning-with-verifiable-rewards stage, with every dataset, script, and recipe published alongside the weights. It targets strong performance on chat as well as math (MATH, GSM8K) and instruction-following (IFEval) benchmarks, and is one entry in a full Tulu 3 family spanning 8B, 70B, and 405B sizes with released SFT, DPO, RLVR, and reward-model checkpoints at each size. At 70.6 billion parameters, it needs a multi-GPU workstation to run in full precision. Context length is 131,072 tokens, inherited from its Llama 3.1 base. It is released under the Llama 3.1 Community License, which requires organizations above 700 million monthly active users to obtain a separate license from Meta. It was published in November 2024.

Frequently Asked Questions
- How much VRAM does Llama 3.1 Tulu 3 70B need?
Llama 3.1 Tulu 3 70B requires 43.3 GB of VRAM at Q4_K_M, or 142.1 GB at BF16. Full 131K context adds up to 42.3 GB (85.6 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 70.6B × 4.8 bits ÷ 8 = 42.3 GB
KV Cache + Overhead ≈ 1 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 43.3 GB (at full 131K context)
VRAM usage by quantization
Q4_K_M43.3 GBQ4_K_M + full context85.6 GB- Can NVIDIA GeForce RTX 4090 run Llama 3.1 Tulu 3 70B?
Yes, at IQ2_XS (22.1 GB) or lower. Higher quantizations like IQ2_M (24.8 GB) exceed the NVIDIA GeForce RTX 4090's 24 GB.
- What's the best quantization for Llama 3.1 Tulu 3 70B?
For Llama 3.1 Tulu 3 70B, Q4_K_M (43.3 GB) offers the best balance of quality and VRAM usage. Q5_K_S (49.5 GB) provides better quality if you have the VRAM. The smallest option is IQ2_XXS at 20.4 GB.
