New Model Available: Cloudflare: Clef

Cloudflare released Clef, an open-source 27B multimodal decision model fine-tuned from Qwen3.8-27B and served on Workers AI, which converts a text or structured JSON state plus a schema of typed questions into a calibrated probability for every allowed option in a single forward pass rather than generating tokens. Clef is aimed at classification, routing, scoring, guardrails and agentic control flow through the Decisions API. Cloudflare notes that Workers AI currently truncates long text state to roughly the first 2K tokens, so content beyond that is not read, while images are counted separately.
