Frequently asked questions

Can OLMo 2 13B run on H200 SXM5 141GB?

Yes. OLMo 2 13B at FP16 needs 36.7 GB including the KV cache, and H200 SXM5 141GB has 141 GB — so it fits on a single GPU.

How fast is OLMo 2 13B on H200 SXM5 141GB?

120.0 tokens/sec per stream and 1440 tok/s aggregate with continuous batching at 8 concurrent users. Time to first token is 468.6 ms, and inter-token latency is 8.3 ms.

What does OLMo 2 13B on H200 SXM5 141GB cost per million tokens?

$0.7716 per 1M output tokens at 1× 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 OLMo 2 13B need on H200 SXM5 141GB?

26.0 GB for the weights at FP16, plus 10.7 GB of KV cache for 8 concurrent requests at 8K context — 36.7 GB total. Every extra concurrent user at long context costs more, so leave headroom.

Is H200 SXM5 141GB the right choice for OLMo 2 13B?

It works. Compare $0.7716 per 1M tokens against the alternatives below — the cheapest option that fits the same workload is 4× RTX 3080 10GB at $0.0717, and the fastest is 1× Cerebras CS-3 (WSE-3) at 6000 tok/s.
