Question 1

How much VRAM does Qwen3.5-397B-A17B-NVFP4-V2 need?

Accepted Answer

Qwen3.5-397B-A17B-NVFP4-V2 (397B) requires approximately 887.3641490936279 GB of VRAM at full precision (FP16), 443.7 GB at 8-bit quantization (Q8), and 221.8 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 Qwen3.5-397B-A17B-NVFP4-V2?

Accepted Answer

We currently have no compatible GPUs indexed for Qwen3.5-397B-A17B-NVFP4-V2. This may be because the model's VRAM requirements exceed available GPUs in our database, or VRAM data hasn't been computed yet.

Question 3

What is the cheapest GPU to run Qwen3.5-397B-A17B-NVFP4-V2?

Accepted Answer

We don't currently have cloud pricing data for GPUs compatible with Qwen3.5-397B-A17B-NVFP4-V2. Cloud pricing data is updated regularly — check back soon.

Question 4

Can Qwen3.5-397B-A17B-NVFP4-V2 run on consumer hardware?

Accepted Answer

Qwen3.5-397B-A17B-NVFP4-V2 requires approximately 887.3641490936279 GB of VRAM at FP16, and even with 4-bit quantization (Q4) it needs about 221.8 GB. This exceeds the 24 GB available on the highest-end consumer GPU (RTX 4090), so Qwen3.5-397B-A17B-NVFP4-V2 requires datacenter or cloud GPUs.

Question 5

What quantization options are available for Qwen3.5-397B-A17B-NVFP4-V2?

Accepted Answer

Qwen3.5-397B-A17B-NVFP4-V2 supports the following quantization levels: FP16 (full precision): ~887.3641490936279 GB, Q8 (8-bit): ~443.7 GB, Q6 (6-bit): ~332.8 GB, Q4 (4-bit): ~221.8 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.
