- Block launched Builderbot, an AI tool that handles 15% of its production code changes.
Jack Dorsey's Block has launched Builderbot, an AI tool that handles 15% of its production code changes, executing over 200,000 operations daily. The system understands the company's entire codebase, enabling faster development cycles and potentially explaining recent layoffs.
Block's development of Builderbot signifies a substantial advancement in the practical application of AI in software engineering, demonstrating that autonomous AI agents can now handle a measurable share of production code, potentially reshaping development workflows and workforce needs.
Jack Dorsey's financial services firm Block has introduced Builderbot, a new AI-native tool designed to manage a significant portion of its software development workflow. The company claims Builderbot can execute approximately 15% of all production code changes, handling over 200,000 operations daily and merging around 1,500 pull requests weekly.
Builderbot functions as an orchestration layer, coordinating multiple AI agents across Block's entire codebase. Unlike typical coding assistants confined to a single repository, Builderbot possesses a comprehensive understanding of all services, APIs, and conventions within the company. This allows engineers to implement changes in any part of the system, even in services they are unfamiliar with.
Block stated that this AI capability has drastically reduced development time, with ideas now progressing from backlog to customer deployment in days rather than months. The company also linked the rapid acceleration of AI, exemplified by Builderbot, to its decision to lay off 40% of its staff in February.
Block is sharing details about Builderbot, believing the transition to AI-native engineering is a critical conversation in the technology sector. The company highlighted that the challenges it addresses, such as orchestrating AI agents across large codebases and maintaining quality at speed, are not unique to Block. Other companies are also leveraging AI for software development, with Spotify developers reportedly writing minimal code since December, and Google CEO Sundar Pichai noting that three-quarters of new code is AI-generated. Microsoft CEO Satya Nadella indicated that 20% to 30% of its software code is now AI-written.
