Energy, memory and cost per answer
From the logs and telemetry you already have. Spend by model and workflow, and what the GPUs drew while they served it.
The workloads that waste capacity
Buried shared documents, repeated questions, retries, oversized context and idle GPUs, largest first.
Replayed on real prompts before it ships
Every change is replayed on real prompts and ships only if answer quality holds.
Headroom in the operator’s own terms
Freed GPUs, watt-hours and CO₂ per answer, and how many requests each instance can hold at once.
