Question 1

How much VRAM does Nemotron-Labs-TwoTower-30B-A3B-Base-BF16 need?

Accepted Answer

Nemotron-Labs-TwoTower-30B-A3B-Base-BF16 (63.2B) requires approximately 141.23149852752684 GB of VRAM at full precision (FP16), 70.6 GB at 8-bit quantization (Q8), and 35.3 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 Nemotron-Labs-TwoTower-30B-A3B-Base-BF16?

Accepted Answer

We have 6 compatible GPUs indexed for Nemotron-Labs-TwoTower-30B-A3B-Base-BF16, including MI300X, B200, B100, MI325X, MI350X and 1 more. 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 Nemotron-Labs-TwoTower-30B-A3B-Base-BF16?

Accepted Answer

The cheapest GPU to run Nemotron-Labs-TwoTower-30B-A3B-Base-BF16 in the cloud is the MI300X at $2.19/hr. Other affordable options include B200 ($5.89/hr). Prices reflect the lowest on-demand rate across cloud providers.

Question 4

Can Nemotron-Labs-TwoTower-30B-A3B-Base-BF16 run on consumer hardware?

Accepted Answer

Nemotron-Labs-TwoTower-30B-A3B-Base-BF16 requires approximately 141.23149852752684 GB of VRAM at FP16, and even with 4-bit quantization (Q4) it needs about 35.3 GB. This exceeds the 24 GB available on the highest-end consumer GPU (RTX 4090), so Nemotron-Labs-TwoTower-30B-A3B-Base-BF16 requires datacenter or cloud GPUs.

Question 5

What quantization options are available for Nemotron-Labs-TwoTower-30B-A3B-Base-BF16?

Accepted Answer

Nemotron-Labs-TwoTower-30B-A3B-Base-BF16 supports the following quantization levels: FP16 (full precision): ~141.23149852752684 GB, Q8 (8-bit): ~70.6 GB, Q6 (6-bit): ~53 GB, Q4 (4-bit): ~35.3 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.
