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.
Next.js creator Guillermo Rauch says Fable cut memory 15-30%
Boris Cherny used Fable to lower p95 latency below 300ms.

@rauchg @tobi This is pretty how I optimize code these days. “Hey fable, use a dynamic workflow to get p95 time down under 300ms. Dont stop till you’re done, use a profiler”
