Sixteen Claude AI agents working together created a new C compiler

Anthropic showcased a groundbreaking achievement where 16 Claude Opus 4.6 AI agents collaborated to develop a new C compiler from scratch. The AI model agents, working independently in Docker containers, successfully created a 100,000-line Rust-based compiler capable of building a bootable Linux 6.9 kernel on various architectures. This compiler, released on GitHub, has demonstrated impressive capabilities by compiling major open source projects and achieving a 99 percent pass rate on the GCC torture test suite. The success of this project highlights the potential of AI in coding tasks with well-defined specifications and comprehensive test suites.
