On Feb 6, 2026, Anthropic reported its Claude Opus 4.6 model used 16 parallel agents to build a 100,000-line Rust-based C compiler in two weeks, consuming about 2,000 sessions and $20,000 in API costs. Led by Nicholas Carlini, the compiler passed 99% of the GCC torture tests and produced bootable Linux 6.9 images for x86, ARM, and RISC-V.
