Rakuten deploys Fable 5 agents for overnight work across business functions
Rakuten reported deploying agents across product, sales, marketing and finance, with issue-closing about ten times faster across domains. Fable 5 extended those systems to overnight and potentially days-long work by checking assumptions and correcting errors without human steering, allowing whole jobs rather than pre-split steps to be delegated.

Magnitude 60 reflects enterprise-wide deployment across multiple functions, tenfold issue-closing speed and a shift from supervised steps to unattended whole-job delegation. Confidence 90 reflects a dated attributable operational case study with deployment breadth, observed speed and model-specific behavior, tempered by vendor selection of the case.
