Frequently asked questions

Can DeepSeek R1 671B (MoE) run on H200 SXM5 141GB?

Yes, but it needs 8× H200 SXM5 141GB. At AWQ 4-bit the total footprint is 631.0 GB (369.1 GB of weights plus 262.0 GB of KV cache at 8K × 8 concurrent users), against 1128 GB of available VRAM across 8 GPUs.

How fast is DeepSeek R1 671B (MoE) on H200 SXM5 141GB?

917.4 tokens/sec per stream and 88075 tok/s aggregate with continuous batching at 8 concurrent users. Time to first token is 184.2 ms, and inter-token latency is 1.1 ms.

What does DeepSeek R1 671B (MoE) on H200 SXM5 141GB cost per million tokens?

$0.1009 per 1M output tokens at 8× H200 SXM5 141GB ($4.00/hr). That is the marginal hardware cost — add idle capacity, ops, and egress for the real figure.

How much VRAM does DeepSeek R1 671B (MoE) need on H200 SXM5 141GB?

369.1 GB for the weights at AWQ 4-bit, plus 262.0 GB of KV cache for 8 concurrent requests at 8K context — 631.0 GB total. Every extra concurrent user at long context costs more, so leave headroom.

Is H200 SXM5 141GB the right choice for DeepSeek R1 671B (MoE)?

It works. Compare $0.1009 per 1M tokens against the alternatives below — the cheapest option that fits the same workload is 8× A100 80GB SXM4 at $0.0727, and the fastest is 8× H200 SXM5 141GB at 88075 tok/s.
