AgentX replays real coding-agent sessions rather than fixed-length prompts, so context grows turn over turn and most of each request is served from cache instead of being recomputed. That turns the comparison into a systems question: KV transfer between nodes, prefix-aware routing, and cache capacity all move the curve alongside raw chip throughput. Fixed-sequence workloads stay the clean baseline for kernel and silicon performance, so the two scenarios answer different questions about the same hardware. Learn more about AgentX →
Only B300 has cost data at 71 tok/s/user on Qwen 3.8 Flash Next 176B-A6B — $0.01 per million tokens. H200 is unmeasured at this target.
B300 costs $0.01 per million tokens at 104 tok/s/user on Qwen 3.8 Flash Next 176B-A6B; we have no H200 benchmark data at this exact target.
At 137 tok/s/user on Qwen 3.8 Flash Next 176B-A6B, B300 comes in at $0.01 per million tokens. H200 hasn't been benchmarked at this operating point.
