Replit launches Agent 3 with 3-hour autonomous coding
Replit just launched Agent 3, an AI developer that can autonomously build, test, and debug code for over three hours straight without human intervention. Backed by a fresh $250M funding round at a $3B valuation, CEO Amjad Masad called it software's "full self-driving moment"—using a multi-agent architecture to boost uninterrupted runtime tenfold over its predecessor.
