Reposted by CodSpeedArthur Pastel @apas.tel · 22/07/2026Frontier models have no runtime performance signal. Not in training data, not as feedback. They can’t measure the code they generate, so they guess. Exciting talk with @heavybit.com about why AI-generated code needs performance guardrails, and what we’re building at @codspeed.io. 011
Reposted by CodSpeedArthur Pastel @apas.tel · 28/05/2026"If you're gonna ship slop, at least make it fast." Our top sticker at PyCon and there's a reason: code has never been cheaper, reviewers are under pressure and regressions are piling up. Stop thinking about performance, we'll make your thing faster. 001
