Sixteen Claude Agents Built a C Compiler Without Human Intervention... Almost

Anthropic successfully demonstrated autonomous AI development by deploying 16 Claude Opus 4.6 agents to build a C-compiler from scratch with minimal human intervention. Working collaboratively on a shared repository, the agents coordinated changes and produced a Rust-based compiler capable of building Linux 6.9 kernel across multiple architectures (x86, ARM, RISC-V) and other open-source projects, showcasing significant advances in autonomous software engineering capabilities.
