Cloudflare releases Clef models for fast structured agent decisions

Cloudflare launched Clef and Clef-flash, built on Qwen and licensed under Apache 2.0, which let AI agents make structured decisions without generating text. Clef-flash returns classifications in about 39 milliseconds, which Cloudflare says is over ten times faster than TypeSafe AI's Jev model.

Why it matters: Small decision models that classify instead of generate make agent steps cheap and fast enough to run on every action. That is the kind of component needed to reduce human review in agent pipelines. It also shows the Jev launch already prompting open, Apache-licensed competition built on Chinese open-weight bases.
