FAQ

Can the NVIDIA H100 NVL run Qwen 3.5 122B A10B?

Yes. The NVIDIA H100 NVL's 94.0GB of VRAM is enough to run Qwen 3.5 122B A10B at Q5_K_M quantization (87.6GB required).

What's the best quantization to use?

Q5_K_M is the highest-precision quantization that fits in your 94.0GB. It uses about 87.6GB of memory and 89.1GB recommended for comfortable inference.

What if I need more headroom for context length?

KV cache memory grows with context length. The numbers above assume a baseline 2K-4K context. For long-context use (32K+), add another 2-6GB depending on the model architecture.
