Mistral 7B v0.3 at FP16 needs 14.5 GB for its weights and 23.1 GB in total at 8K context with 8 concurrent users. That means it fits on a single V100 SXM2 32GB. Every figure is computed by tokcalc's open-source capacity model.

Yes. Mistral 7B v0.3 at FP16 needs 23.1 GB including the KV cache, and V100 SXM2 32GB has 32 GB — so it fits on a single GPU.
40.40 tokens/sec per stream and 484.8 tok/s aggregate with continuous batching at 8 concurrent users. Time to first token is 1.95 s, and inter-token latency is 24.8 ms.
$0.2865 per 1M output tokens at 1× V100 SXM2 32GB ($0.5000/hr). That is the marginal hardware cost — add idle capacity, ops, and egress for the real figure.
14.5 GB for the weights at FP16, plus 8.6 GB of KV cache for 8 concurrent requests at 8K context — 23.1 GB total. Every extra concurrent user at long context costs more, so leave headroom.
It works. Compare $0.2865 per 1M tokens against the alternatives below — the cheapest option that fits the same workload is 4× RTX 3080 10GB at $0.0399, and the fastest is 1× Cerebras CS-3 (WSE-3) at 10773 tok/s.
