Question 1

How much VRAM does Qwen3-30B-A3B-Instruct-2507 need?

Accepted Answer

Qwen3-30B-A3B-Instruct-2507 (30.5B) requires approximately 67.05522537231445 GB of VRAM at full precision (FP16), 33.5 GB at 8-bit quantization (Q8), and 16.8 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 Qwen3-30B-A3B-Instruct-2507?

Accepted Answer

We have 10 compatible GPUs indexed for Qwen3-30B-A3B-Instruct-2507, including A100 80GB PCIe, A100 80GB, H100 MEGA, H100 SXM, H100 NVL and 5 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 Qwen3-30B-A3B-Instruct-2507?

Accepted Answer

The cheapest GPU to run Qwen3-30B-A3B-Instruct-2507 in the cloud is the A100 80GB PCIe at $1.39/hr. Other affordable options include A100 80GB ($1.39/hr) and H100 MEGA ($1.80/hr). Prices reflect the lowest on-demand rate across cloud providers.

Question 4

Can Qwen3-30B-A3B-Instruct-2507 run on consumer hardware?

Accepted Answer

Yes, Qwen3-30B-A3B-Instruct-2507 can run on consumer GPUs like the RTX Pro 6000 Blackwell (96 GB VRAM) at full precision (FP16).

Question 5

What quantization options are available for Qwen3-30B-A3B-Instruct-2507?

Accepted Answer

Qwen3-30B-A3B-Instruct-2507 supports the following quantization levels: FP16 (full precision): ~67.05522537231445 GB, Q8 (8-bit): ~33.5 GB, Q6 (6-bit): ~25.1 GB, Q4 (4-bit): ~16.8 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), Qwen3-30B-A3B-Instruct-2507 has a larger total weight size but only activates a subset of parameters per token, which can affect effective memory usage during inference.
