Sixteen AI Agents Built a C Compiler From Scratch
Anthropic researcher Nicholas Carlini set 16 instances of Claude Opus 4.6 loose on a shared codebase over two weeks to build a C compiler from scratch, and the AI agents produced a 100,000-line Rust-based compiler capable of building a bootable Linux 6.9 kernel on x86, ARM and RISC-V architectures.

The project ran through nearly 2,000 Claude Code sessions and cost abou … ⌘ Read more
