Dorsey’s Block says new AI tool handles 15% of code work
Block launched AI-native engineering tools centered on Builderbot, an orchestration layer that coordinates multiple AI agents across its full codebase. Block says the system can carry out about 15% of production code changes, perform more than 200,000 operations a day, and merge roughly 1,500 pull requests weekly. Unlike a normal coding assistant, Builderbot understands Block’s services, APIs, and conventions across repos, letting engineers make changes in unfamiliar parts of the system while the AI handles repetitive work. Block presents this as a shift from AI-assisted coding to AI-native software engineering, where ideas can move from backlog to production in days instead of months. The rollout also reinforces why Block said AI helped justify a 40% staff cut earlier this year. Similar AI coding adoption is growing at Spotify, Google, and Microsoft.
