Question 1

How much VRAM does Llama-3.1-Tulu-3-70B-SFT need?

Accepted Answer

Llama-3.1-Tulu-3-70B-SFT (70.6B) requires approximately 157.70011596679686 GB of VRAM at full precision (FP16), 78.9 GB at 8-bit quantization (Q8), and 39.4 GB at 4-bit quantization (Q4). The actual VRAM usage may be slightly higher due to KV cache and runtime overhead.

Question 2

What GPUs can run Llama-3.1-Tulu-3-70B-SFT?

Accepted Answer

We have 5 compatible GPUs indexed for Llama-3.1-Tulu-3-70B-SFT, including MI300X, B200, B100, MI325X, MI350X. Compatibility is determined by whether the GPU's VRAM can fit the model's memory footprint, potentially using quantization to reduce memory usage.

Question 3

What is the cheapest GPU to run Llama-3.1-Tulu-3-70B-SFT?

Accepted Answer

The cheapest GPU to run Llama-3.1-Tulu-3-70B-SFT in the cloud is the MI300X at $1.99/hr. Other affordable options include B200 ($5.50/hr). Prices reflect the lowest on-demand rate across cloud providers.

Question 4

Can Llama-3.1-Tulu-3-70B-SFT run on consumer hardware?

Accepted Answer

Llama-3.1-Tulu-3-70B-SFT requires approximately 157.70011596679686 GB of VRAM at FP16, and even with 4-bit quantization (Q4) it needs about 39.4 GB. This exceeds the 24 GB available on the highest-end consumer GPU (RTX 4090), so Llama-3.1-Tulu-3-70B-SFT requires datacenter or cloud GPUs.

Question 5

What quantization options are available for Llama-3.1-Tulu-3-70B-SFT?

Accepted Answer

Llama-3.1-Tulu-3-70B-SFT supports the following quantization levels: FP16 (full precision): ~157.70011596679686 GB, Q8 (8-bit): ~78.9 GB, Q6 (6-bit): ~59.1 GB, Q4 (4-bit): ~39.4 GB. Lower quantization reduces VRAM usage at the cost of some quality loss. Q8 offers a good balance between quality and memory savings, while Q4 provides maximum compression.
