About Clef-flash

Clef-flash is the smaller, latency-optimised member of Cloudflare's Clef decision-model family, released on 1 October 2026. Like Clef, it returns structured answers chosen from a defined set, each with a probability, rather than free text. It is meant for agents that make many routine classifications, where response time matters more than the last points of accuracy.

What Clef-flash does

  • Structured classification: text or images are sorted into bounded answers, each scored with a probability.
  • Low latency: built for high-volume decisions where response time is the priority.
  • Open weights: published on Hugging Face under the Apache 2.0 licence, and it runs on Workers AI.
  • Escalation path: the larger Clef model is available for harder cases.

Who it works with

Teams running agents that make high-volume decisions, where response time matters.
