Where the money leaks
Most legal & law pay for cloud and AI capacity they don't fully use — commitments and right-sizing usually recover 20–40%*.
The biggest line is rarely the one being watched — one lever (caching, routing, or a commitment) usually moves it most.
Without per-team attribution, no one owns the number — showback makes the savings stick.
AWS — the layers to optimize
Your bill is really two bills: the AI/API spend, and the cloud infrastructure underneath it. Each layer below has market tools that do it.
