Base44 delegates senior-only engineering jobs to Fable 5
Base44 reported assigning Fable 5 work previously reserved for its three most senior engineers. After roughly an hour of questions, the model worked autonomously for four hours and delivered 90% to 95% of a system-prompt rebuild; it also produced about 90% of a mobile-development environment for a product manager in two and a half hours.
