Released on 1 October 2026, with no service record and no entry in the Workers AI changelog we read.\n\n**OpenAI Decisions API.** Typed predicate, choice and score answers with probabilities, up to 200 questions a call, at $0.10 per million input tokens with no output charge. It is a public beta released on 6 October 2026, with one model alias, no dated snapshot, no Batch route and no SLA found.\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### OpenAI Decisions API\n\n1. Put independent questions about one input in a single `questions` array. Send a separate request when a question depends on an earlier answer\n2. Check each answer's `type` before reading it. A question can come back as `refusal` while the others in the same request are answered\n3. Encode images as base64 data URLs. Hosted URLs and `file_id` inputs are rejected\n4. Give a `choice` question a fallback value such as `other`, and set thresholds from your own labelled examples\n5. Use Python SDK 3.26.0 or JavaScript 7.30.0 or later, and follow `Retry-After` on 429 and 503\n\n## Questions\n\n### Which is better for AI agents, Clef or OpenAI Decisions API?\n\nOpenAI Decisions API scores 71.5 (BB) on agent readiness against Clef's 66.1 (B), and leads in 4 of 7 scored categories. Clef leads on reliability and payments \u0026 pricing.\n\n### Do Clef and OpenAI Decisions API need an API key?\n\nBoth need an API key.\n\n### Can an agent call Clef and OpenAI Decisions API without installing anything?\n\nYes.
