Released on 1 October 2026, with no service record and no entry in the Workers AI changelog we read.\n\n**pplx-decider.** The hosted Decisions API has an OpenAPI description, typed questions, documented limits and a published price of $0.02 per million input tokens, and the v1.1 weights are public under Apache-2.0. The API is days old, the official Python SDK has no method for it, and the governing terms and privacy notice could not be read on 9 October 2026.\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### pplx-decider\n\n1. Send `Authorization: Bearer`. A key in `x-api-key` returns 401 on this endpoint.\n2. Set `model` on every request. A missing or unknown model returns 400, and the guide shows a `-latest` name rejected.\n3. Resize images to 2,048 tiles of 32 by 32 pixels or fewer before sending. Larger images end in a 504 after about a minute.\n4. Check the HTTP status before parsing an error. 404 and 405 have empty bodies, 504 can be HTML, and `error.code` changes type.\n5. For the weights, use the repository's `autojev` code. The card says default causal inference does not reproduce the evaluated setup.\n\n## Questions\n\n### Which is better for AI agents, Clef or pplx-decider?\n\nClef scores 66.1 (B) on agent readiness against pplx-decider's 62.9 (B), and leads in 3 of 7 scored categories. pplx-decider leads on schema \u0026 documentation and maintenance \u0026 community.\n\n### Do Clef and pplx-decider need an API key?\n\nBoth need an API key.\n\n### Can an agent call Clef and pplx-decider without installing anything?\n\nYes. Clef has a hosted endpoint at https://api.cloudflare.com/client/v4/accounts/{account_id}/ai/run/@cf/cloudflare/clef and pplx-decider at https://api.perplexity.ai/v1/decisions.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/cloudflare-clef-vs-pplx-decider.json, and with the fewest tokens: https://www.anchorterminal.com/compare/cloudflare-clef-vs-pplx-decider.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"cloudflare-clef\", \"b\": \"pplx-decider\"}`.
