Agent Compute Unit (ACU)

An Agent Compute Unit (ACU) is a vendor-defined metering unit that bundles the compute an agent consumes to do work, used to bill usage-based agent pricing.

ACUs abstract away tokens and infrastructure into a single billable unit, but each vendor defines an ACU differently, so they are not directly comparable across providers.

Buyers typically convert ACU-based pricing into a price per outcome to benchmark it consistently.
