While classifier models have been around for some time, Jev introduces a new decision model concept into the world of AI — a model that produces bounded structured outputs cheaply, quickly and consistently that can be added into a workflow when a decision is required. These models are capable enough to work over any set of inputs without constantly retraining the model to incorporate new classification categories. This contrasts with the world of Large Language Models (LLMs), which are largely non-deterministic, but are open-ended enough to reason and generate text and tool calls for agentic workloads. Today, we’re releasing two Cloudflare-trained decision models, Clef and Clef-flash, hosted on Workers AI . Clef is currently the leader when evaluated against the Jev Decision Index , you can view full results on the live benchmark demo site . These models are smarter, faster, and fully Jev-API compatible, so you can experiment with these hosted..."},"evidence_pages":[],"related_signals":[{"id":"9c9d357b-b379-4de0-ab2c-30764ba08632","url":"https://onlylabs.fyi/signals/9c9d357b-b379-4de0-ab2c-30764ba08632","source_url":"https://blog.cloudflare.com/origin-range-requests/","title":"Origin Range Requests: Serving large files without range-request tuning","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"cloudflare","name":"Cloudflare (Workers AI)","category":"neocloud"},"occurred_at":"2026-10-23T18:22:59+00:00","first_seen_at":"2026-10-23T20:00:52.925659+00:00","date_source":"rss.item_date"},{"id":"36b8c4da-4f96-4abc-8a89-7ff3e47942cd","url":"https://onlylabs.fyi/signals/36b8c4da-4f96-4abc-8a89-7ff3e47942cd","source_url":"https://blog.cloudflare.com/post-quantum-geo-key-manager/","title":"Bringing post-quantum cryptography to geographically fenced key management","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"cloudflare","name":"Cloudflare (Workers AI)","category":"neocloud"},"occurred_at":"2026-10-23T18:06:56+00:00","first_seen_at":"2026-10-23T20:00:52.925659+00:00","date_source":"rss.item_date"},{"id":"d9e0cfd4-b38f-4c15-bd9e-81cfe0ac8dfb","url":"https://onlylabs.fyi/signals/d9e0cfd4-b38f-4c15-bd9e-81cfe0ac8dfb","source_url":"https://blog.cloudflare.com/k-isms/","title":"Localizing compliance at scale: achieving South Korea’s ISMS certification","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"cloudflare","name":"Cloudflare (Workers AI)","category":"neocloud"},"occurred_at":"2026-10-22T13:00:00+00:00","first_seen_at":"2026-10-22T16:00:54.670606+00:00","date_source":"rss.item_date"},{"id":"c52bb1e0-df36-4ab7-b8cd-a48a6f37dfef","url":"https://onlylabs.fyi/signals/c52bb1e0-df36-4ab7-b8cd-a48a6f37dfef","source_url":"https://blog.cloudflare.com/full-transaction-waf/","title":"Introducing full transaction detection for Cloudflare WAF","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"cloudflare","name":"Cloudflare (Workers AI)","category":"neocloud"},"occurred_at":"2026-10-21T14:10:42+00:00","first_seen_at":"2026-10-21T16:00:52.275864+00:00","date_source":"rss.item_date"},{"id":"6c59f359-43de-4c9d-be79-876752c91605","url":"https://onlylabs.fyi/signals/6c59f359-43de-4c9d-be79-876752c91605","source_url":"https://blog.cloudflare.com/php-vulnerabilities-waf-protection/","title":"Cloudflare deploys protections against php2shell vulnerability","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"cloudflare","name":"Cloudflare (Workers AI)","category":"neocloud"},"occurred_at":"2026-10-21T13:56:45+00:00","first_seen_at":"2026-10-21T16:00:52.275864+00:00","date_source":"rss.item_date"},{"id":"7cf512fd-f264-4ff0-ba38-acd212a3e47e","url":"https://onlylabs.fyi/signals/7cf512fd-f264-4ff0-ba38-acd212a3e47e","source_url":"https://blog.cloudflare.com/webmcp-commerce/","title":"How Commerce.com and Cloudflare are getting storefronts ready for AI agents","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"cloudflare","name":"Cloudflare (Workers AI)","category":"neocloud"},"occurred_at":"2026-10-21T13:00:00+00:00","first_seen_at":"2026-10-21T16:00:52.275864+00:00","date_source":"rss.item_date"}]}
