Cloudflare open-sources decision model Clef, outperforming Jev within weeks
michellechen · x · 2026-10-02
- Cloudflare released and open-sourced its decision model Clef, hitting Hacker News front page (139 points, 49 comments).
- Commenters were struck that Cloudflare built, in just weeks on Typesafe's new Jev paradigm, a model that outranks Jev on Typesafe's own benchmark — noting Cloudflare already runs decision models in production for bot, DDoS and spam detection.
- One popular take: it's not a new paradigm but a low-hanging fruit Typesafe was first to pick and market; the AI frontier's speed leaves many such fruits unpicked — enough for a decade of progress even if SOTA LLMs plateaued.
- Pricing came up too, seen as somewhat more expensive.
