TrustList summary

Clef is an open-weight decision model from Cloudflare, released on 1 October 2026 under the Apache 2.0 licence. Rather than writing free text, it picks from a defined set of answers and gives a probability for each, so agents can make routine calls such as routing, moderation or approval without a person checking each one.

Main features

  • Typed classification: text or images are sorted into bounded answers, each with a probability.
  • Fine-tuning on customer data: Cloudflare offers reinforcement-learning fine-tuning on a customer's own data, first as a service run by its engineers, with a self-serve version to follow.
  • Open weights: the weights are published on Hugging Face under Apache 2.0.
  • Hosted option: the model also runs on Cloudflare's Workers AI.
