Pure flour-power. Hearty enough to carry you through lunch.
Summary
A company used AI to rewrite JSONata, a JSON transformation language, as a pure-Go library called gnata in just seven hours with $400 in AI tokens. This resulted in a 1,000x performance improvement and projected annual savings of $500,000 on cloud infrastructure costs. The approach was inspired by Cloudflare's similar AI-driven rewrite of Next.js, demonstrating how AI can rapidly reimplement existing software with significant efficiency gains.

Seven hours, $400 in tokens, 1,000x speedup, and $500K/year off our cloud bill.
They took the existing Next.js spec and test suite, then pointed AI at it and had it implement code until every test passed.
Midway through reading, I realized we had the exact same problem - only in our case, it was with our JSON transformation pipeline.
