contract: limited to a hard cap of its interactive peak plus 2% (22.531 GiB with room for its CUDA context), the engine neither held its requests at once nor kept 90% of its rate; limited to a hard cap of its serve peak plus 2% (33.576 GiB with room for its CUDA context), the engine neither held its requests at once nor kept 90% of its rate

W·A·KV W4A4KV8 declared · the service reads W16A16KV8
Drift from BF16KL 0.027 nats per token
Speed gain— BF16 in the same pod (gate: at least 0.95× less its error)
Memory gain— BF16's peak · — GiB against BF16's — GiB on the first workload
Per-domain results on the hidden split are not released.

Engine: 15.1 GiB of weights held, 16.3 GiB stored.
