Released on 1 October 2026, with no service record and no entry in the Workers AI changelog we read.\n\n**Decider.** An Apache-2.0 decision model family with a dated changelog, passing CI, 21 package releases since 22 September 2026 and model cards that list measured regressions. One person maintains it, the local server has no authentication option, states over 32,768 tokens are cut without an error, and no security policy is published.\n\n## Before you call either\n\n### Clef\n\n1. Send `model` as `clef` or `clef-flash` in the body as well as the model in the URL. The input schema requires it\n2. Ask every independent question about one state in one call. Up to 64 are allowed\n3. Try `clef-flash` first for text-only triage. It costs $0.09 per million input tokens against $0.24\n4. Read the internal code on a 429. 3036 means the day's 10,000 free neurons are spent, 3040 means capacity, so retry later\n5. Treat an answer about user-supplied text as a judgement that hostile input can steer. Cloudflare publishes no guidance on it\n\n### Decider\n\n1. Pin weights by Hub tag (`v10`, `v2`) when results must repeat. The `main` branch of each model repository changes with new versions\n2. Read `x_p_max` for the top probability. Since 1.3.0 `confidence` on choice and score answers follows TypeSafe's rescaled definition, not the top probability\n3. Keep the server on 127.0.0.1 or put an authenticating proxy in front. It has no key option\n4. Count state tokens before sending. Over 32,768 the state is cut silently, and `/decide` caps context at 1,536 tokens\n5. Split multi-step arithmetic or multi-hop judgements into several questions, and don't write long rules into a question. The README says both fail\n\n## Questions\n\n### Which is better for AI agents, Clef or Decider?\n\nDecider scores 69.5 (B) on agent readiness against Clef's 66.1 (B), and leads in 5 of 7 scored categories. Clef leads on security \u0026 auth and transparency \u0026 trust.\n\n### Do Clef and Decider need an API key?\n\nClef needs an API key. Decider needs no key.\n\n### Can an agent call Clef and Decider without installing anything?\n\nClef has a hosted endpoint at https://api.cloudflare.com/client/v4/accounts/{account_id}/ai/run/@cf/cloudflare/clef. No hosted endpoint is listed for Decider.\n\n### Are Clef and Decider open source?\n\nNo open-source release is listed for Clef. Decider is open source (Apache-2.0 (code and weights)).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/cloudflare-clef-vs-decider.json, and with the fewest tokens: https://www.anchorterminal.com/compare/cloudflare-clef-vs-decider.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"cloudflare-clef\", \"b\": \"decider\"}`.
