Question 1

How much VRAM does Hy-Memory-30B-A3B need?

Accepted Answer

Hy-Memory-30B-A3B (30.1B) requires approximately 132.75981903076172 GB of VRAM at full precision (FP16), 66.4 GB at 8-bit quantization (Q8), and 33.2 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 Hy-Memory-30B-A3B?

Accepted Answer

We have 7 compatible GPUs indexed for Hy-Memory-30B-A3B, including H200 SXM, MI300X, MI350X, B200, B100 and 2 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 Hy-Memory-30B-A3B?

Accepted Answer

The cheapest GPU to run Hy-Memory-30B-A3B in the cloud is the H200 SXM at $2.35/hr. Other affordable options include MI300X ($2.39/hr) and MI350X ($5.49/hr). Prices reflect the lowest on-demand rate across cloud providers.

Question 4

Can Hy-Memory-30B-A3B run on consumer hardware?

Accepted Answer

Hy-Memory-30B-A3B requires approximately 132.75981903076172 GB of VRAM at FP16, and even with 4-bit quantization (Q4) it needs about 33.2 GB. This exceeds the 24 GB available on the highest-end consumer GPU (RTX 4090), so Hy-Memory-30B-A3B requires datacenter or cloud GPUs.

Question 5

What quantization options are available for Hy-Memory-30B-A3B?

Accepted Answer

Hy-Memory-30B-A3B supports the following quantization levels: FP16 (full precision): ~132.75981903076172 GB, Q8 (8-bit): ~66.4 GB, Q6 (6-bit): ~49.8 GB, Q4 (4-bit): ~33.2 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. As a Mixture of Experts (MoE) model with 128 experts (8 active), Hy-Memory-30B-A3B has a larger total weight size but only activates a subset of parameters per token, which can affect effective memory usage during inference.
