A developer used models like GPT-5.6 and Claude Opus 5.5 to fully port the TypeScript compiler, checker, and LSP to Rust (tsc-rs) via iterative goal loops. The project consumed over $420,000 in API tokens, generating 1.3 million lines of code while achieving 100% compatibility in real-world projects. The new tool supports high-performance WASM execution, demonstrating the practical viability of LLMs in complex system-level code refactoring.

    • LLMs can independently complete million-line cross-language compiler ports, but require massive compute costs (~$420k)
    • The generated tsc-rs tool achieves 100% behavioral compatibility in real open-source projects and supports high-performance WASM deployment
    • The project utilized a 'goal loop' strategy, combining GPT-5.6 and Claude Opus 5.5 for final delivery
