GLM-5.3 (MoE) at AWQ 4-bit needs 414.3 GB for its weights and 420.2 GB in total at 8K context with 8 concurrent users. That means it needs 4× B200 SXM 192GB. Every figure is computed by tokcalc's open-source capacity model.

Yes, but it needs 4× B200 SXM 192GB. At AWQ 4-bit the total footprint is 420.2 GB (414.3 GB of weights plus 5.9 GB of KV cache at 8K × 8 concurrent users), against 768 GB of available VRAM across 4 GPUs.
1480 tokens/sec per stream and 71027 tok/s aggregate with continuous batching at 8 concurrent users. Time to first token is 135.1 ms, and inter-token latency is 675.8 µs.
$0.0939 per 1M output tokens at 4× B200 SXM 192GB ($6.00/hr). That is the marginal hardware cost — add idle capacity, ops, and egress for the real figure.
414.3 GB for the weights at AWQ 4-bit, plus 5.9 GB of KV cache for 8 concurrent requests at 8K context — 420.2 GB total. Every extra concurrent user at long context costs more, so leave headroom.
It works. Compare $0.0939 per 1M tokens against the alternatives below — the cheapest option that fits the same workload is 8× A100 80GB SXM4 at $0.0375, and the fastest is 8× H100 SXM5 80GB at 118970 tok/s.
