Frequently asked questions

Can Mistral Large 3 (256K) run on B200 SXM 192GB?

Yes. Mistral Large 3 (256K) at AWQ 4-bit needs 150.2 GB including the KV cache, and B200 SXM 192GB has 192 GB — so it fits on a single GPU.

How fast is Mistral Large 3 (256K) on B200 SXM 192GB?

117.2 tokens/sec per stream and 1406 tok/s aggregate with continuous batching at 8 concurrent users. Time to first token is 1.59 s, and inter-token latency is 8.5 ms.

What does Mistral Large 3 (256K) on B200 SXM 192GB cost per million tokens?

$1.19 per 1M output tokens at 1× B200 SXM 192GB ($6.00/hr). That is the marginal hardware cost — add idle capacity, ops, and egress for the real figure.

How much VRAM does Mistral Large 3 (256K) need on B200 SXM 192GB?

129.3 GB for the weights at AWQ 4-bit, plus 20.9 GB of KV cache for 8 concurrent requests at 8K context — 150.2 GB total. Every extra concurrent user at long context costs more, so leave headroom.

Is B200 SXM 192GB the right choice for Mistral Large 3 (256K)?

It works. Compare $1.19 per 1M tokens against the alternatives below — the cheapest option that fits the same workload is 8× RTX 5090 32GB at $0.0648, and the fastest is 4× Cerebras CS-3 (WSE-3) at 47811 tok/s.
