Frequently asked questions

Can Mistral Large 3 (256K) run on A100 80GB SXM4?

Yes, but it needs 2× A100 80GB SXM4. At AWQ 4-bit the total footprint is 150.2 GB (129.3 GB of weights plus 20.9 GB of KV cache at 8K × 8 concurrent users), against 160 GB of available VRAM across 2 GPUs.

How fast is Mistral Large 3 (256K) on A100 80GB SXM4?

49.80 tokens/sec per stream and 1195 tok/s aggregate with continuous batching at 8 concurrent users. Time to first token is 3.78 s, and inter-token latency is 20.1 ms.

What does Mistral Large 3 (256K) on A100 80GB SXM4 cost per million tokens?

$0.5578 per 1M output tokens at 2× A100 80GB SXM4 ($1.20/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 A100 80GB SXM4?

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 A100 80GB SXM4 the right choice for Mistral Large 3 (256K)?

It works. Compare $0.5578 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.
