Description

What it is and what it is for

AI-assisted draft · independently checked

The maker says decision models are meant for cases where software needs a quick, consistent decision, such as where to route a support message, whereas open-ended language models are largely non-deterministic. Decision models address this by classifying a situation and returning probabilities that other software can act on. Clef and Clef-flash are Cloudflare's decision models, announced on October 1, 2026. The maker describes Clef as a 27B multimodal decision model and Clef-flash as a fast 9B one, each turning a state and a schema of typed questions into decisions.
