Llama 3.1 Tulu 3 70B DPO — Hardware Requirements & GPU Compatibility
ChatLlama-3.1-Tulu-3-70B-DPO is Allen Institute for AI's (Ai2's) 70.6-billion-parameter instruction-following model, fine-tuned from Meta's Llama 3.1 70B base through Ai2's fully open Tulu 3 post-training recipe. This checkpoint is the direct preference optimization (DPO) stage, trained on Ai2's published preference mixture on top of the Tulu-3-70B-SFT model; a further RLVR stage produces the final Tulu-3-70B release. Tulu 3 targets strong performance not just on chat but on tasks like MATH, GSM8K, and IFEval, with all training data, code, and recipes released openly as a reference post-training pipeline. At 70.6 billion parameters, it needs a multi-GPU workstation or server to run, even once quantized. Context length is 131,072 tokens, inherited from the Llama 3.1 base. It is released under Meta's Llama 3.1 Community License, a custom license that is free for most commercial and research use but requires organizations with more than 700 million monthly active users to request separate permission from Meta. It was published in November 2024.

Frequently Asked Questions
- How much VRAM does Llama 3.1 Tulu 3 70B DPO need?
Llama 3.1 Tulu 3 70B DPO 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 DPO?
Yes, at IQ2_S (23.0 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 DPO?
For Llama 3.1 Tulu 3 70B DPO, 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.
