Cloudflare Open-Sources Clef Decision Models: Classifies in 2.2s vs 4.7s for gpt-oss-120b
dl_weekly · x · 2026-10-10
Cloudflare released Clef and Clef-flash, two decision models under Apache 2.0 on Hugging Face and Workers AI, plus a new RL fine-tuning platform for customizing them. Decision models — a category popularized by Typesafe AI's Jev System One — produce bounded, structured, cheap and consistent classification outputs for agent workflows without retraining on new categories. Clef adds a vision encoder and a 64k context window (vs Jev's 32k), currently leads the Jev Decision Index, and classified a domain in 2.2s versus 4.7s for gpt-oss-120b. Both are fully Jev-API compatible.
