Freu AI's approach is observe-once, compile, execute-forever: a human performs a workflow, the agent records and compiles it into a locally-runnable program, and from that point forward execution runs without calling a model on every step. The vendor positions this as the core cost argument — token spend happens during the learning phase, not during the thousands of subsequent runs. That architecture fits invoice routing through ERPs, clinical evidence extraction, and batch record migration across legacy systems that have no API surface. The wall appears when a workflow changes: any meaningful UI or process shift requires a new learning pass, which means ongoing human expert time isn't eliminated, just front-loaded.
