From Guillermo Rauch (Vercel CEO) on X:
Fable just found a 15-30% memory efficiency improvement in Turbopack / Next.js, nearly autonomously.
@tobi asked me today: what have been your “holy s***” moments with AI?
My answer was: it’s every single week. And it’s accelerating. In fact, “WTFs/day” might just be my favorite metric for AI progress.
It’s one thing to read benchmarks or stories online. It’s another to watch these machines pull engineering feats every day.
3 days ago? Sol helped us find novel vulnerabilities in some of the most audited code in the world. Today? Fable helps us ship this large optimization of a very complex Rust codebase. I just saw some results of work we’ve done to shrink binaries by 10-20x. List goes on.
