They're hosted on Workers AI, API-compatible with Typesafe AI's Jev System One, and released on Hugging Face under an Apache 2.0 license so anyone can run them locally. Cloudflare built Clef on the Qwen base model using a prefill-only, non-autoregressive approach - it scores possible answers in parallel instead of generating text token by token, which is why it's quick. On Cloudflare's own Threat Intelligence team, Clef classified a website's category in 2.2 seconds versus 4.7 seconds for the general-purpose gpt-oss-120b model, and returned more categories in the process.\n\nDecision models matter because they let software make routing and escalation calls without waiting on a slower, non-deterministic LLM or a human in the loop. That's a real cost and latency lever for agentic workflows running at scale - ticket triage, fraud screening, content moderation - where the task is \"pick one of these options with a confidence score,\" not \"write me something.\" Pairing the model with Cloudflare's own edge GPU hosting is also a business pitch: it isn't just selling a model, it's selling the infrastructure to put that model in the hot path.\n\nThe benchmarks are self-reported and the category is only a few weeks old, so Cloudflare's \"we beat Jev\" claims are worth independent verification before anyone takes them as settled.","[\"cloudflare\",\"decision-models\",\"open-source\",\"workers-ai\"]","2026-10-01T15:34:02.000Z","2026-10-02T14:24:06.838Z","2026-10-02T14:24:12.259Z","published",null,[],"ai",[26,27,28,29],"cloudflare","decision-models","open-source","workers-ai",[31],{"name":32,"url":33},"Cloudflare Blog","https:\u002F\u002Fblog.cloudflare.com\u002Fclef-decision-models\u002F",0,{"sections":36},[37,41,46,51,56,61,66,71,76,81,86,91,96,101],{"name":38,"slug":24,"count":39,"latest_published_at":40},"AI",5706,"2026-10-01T18:14:42.000Z",{"name":42,"slug":43,"count":44,"latest_published_at":45},"Security","security",829,"2026-10-01T17:31:56.000Z",{"name":47,"slug":48,"count":49,"latest_published_at":50},"Policy","policy",437,"2026-10-01T18:10:00.000Z",{"name":52,"slug":53,"count":54,"latest_published_at":55},"Deals","deals",314,"2026-10-01T18:26:57.000Z",{"name":57,"slug":58,"count":59,"latest_published_at":60},"Hardware","hardware",198,"2026-10-01T17:38:48.000Z",{"name":62,"slug":63,"count":64,"latest_published_at":65},"Science","science",167,"2026-10-01T18:35:55.000Z",{"name":67,"slug":68,"count":69,"latest_published_at":70},"Consumer Tech","consumer-tech",154,"2026-10-01T18:42:25.000Z",{"name":72,"slug":73,"count":74,"latest_published_at":75},"Dev Tools","dev-tools",95,"2026-10-01T16:57:03.000Z",{"name":77,"slug":78,"count":79,"latest_published_at":80},"Software","software",93,"2026-09-30T21:41:11.000Z",{"name":82,"slug":83,"count":84,"latest_published_at":85},"Startups","startups",89,"2026-10-01T15:12:27.000Z",{"name":87,"slug":88,"count":89,"latest_published_at":90},"Gaming","gaming",52,"2026-10-01T16:12:23.000Z",{"name":92,"slug":93,"count":94,"latest_published_at":95},"General","general",50,"2026-09-30T21:37:54.000Z",{"name":97,"slug":98,"count":99,"latest_published_at":100},"Reviews","reviews",31,"2026-09-28T14:31:34.000Z",{"name":102,"slug":103,"count":104,"latest_published_at":105},"How-To","how-to",7,"2026-10-01T09:00:00.000Z"]
