Meet @cf/cloudflare/clef and @cf/cloudflare/clef-flash , the first models trained by the Cloudflare Workers AI team, available on Workers AI today. Clef is a decision model, in the same family as Typesafe’s Jev ↗︎ . Instead of generating text, it reads an input state and a set of typed questions, then returns a probability for every allowed answer.
