Cloudflare releases typed decision models for agent routing and guardrails

Cloudflare launched Clef and Clef-flash on Workers AI. They score allowed answers to typed questions rather than generating free-form prose, giving applications structured probabilities for routing, classification and action checks. The models support visual inputs and a 64k context window; official model pages and Cloudflare-owned Hugging Face distribution corroborate availability. Flash weights are published with an Apache-2.0 license. Fine-tuning starts as a hands-on service; a self-serve RL platform is future work, not an available turnkey product.
