Clef: Open-weight decision models, and new RL fine-tuning platform

What happened

Cloudflare has released two open‑source decision models, Clef and Clef‑flash, hosted on Workers AI. These models produce fast, deterministic, structured outputs that can be used in workflows where a decision is needed, such as routing support tickets or classifying website domains. They are compatible with the Jev API and are available on Hugging Face under an Apache 2.0 license. Cloudflare also launched a reinforcement‑learning platform that lets developers fine‑tune Clef with their own data. The models can handle text and images, offering up to twice the speed of a comparable large language model in certain tasks.

Why it matters

The new models could reduce the need for human intervention in routine decision tasks, speeding up processes like threat detection and customer support. Developers can quickly integrate these models into applications without training from scratch.

Reality check

Incremental. The models build on existing decision‑model concepts and add speed and fine‑tuning options, but do not represent a fundamental shift in AI technology.
