Released on 1 October 2026, with no service record and no entry in the Workers AI changelog we read.\n\n**Vela 2.0.** One self-hosted call answers routing, prompt-attack, personal-data and unsupported-claim questions with probabilities and character offsets, under Apache-2.0 with SHA-256 manifests. The models are days old and carry no Hub version tags, and the three larger sizes keep 74 to 89 per cent of their Decision 2.0 bases on the Jev Decision Index by the authors' figures.\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### Vela 2.0\n\n1. Pin a commit hash with `revision=` when loading from the Hub. The repositories have no tags and `main` has changed since launch\n2. Send the served name in `model`, for example `vllm-sr/Vela-2.0-4B`. The bundled server answers 422 to any other name\n3. Name span questions `pii`, `halu` or `toxic`, or set `\"head\": \"router\"`, to get the trained router head. Other labels go to the broad head\n4. Keep input under 16,384 tokens a sequence (8,192 on the 0.3B). The bundled server answers 413 when the questions alone don't fit\n5. Set `VELA2_API_KEY` before binding the bundled server beyond 127.0.0.1, and keep the model runtime on a trusted network\n\n## Questions\n\n### Which is better for AI agents, Clef or Vela 2.0?\n\nVela 2.0 and Clef score within a point of each other on agent readiness, 66.5 (B) and 66.1 (B). Clef leads on security \u0026 auth and transparency \u0026 trust.\n\n### Do Clef and Vela 2.0 need an API key?\n\nClef needs an API key. Vela 2.0 needs no key.\n\n### Can an agent call Clef and Vela 2.0 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 Vela 2.0.\n\n### Are Clef and Vela 2.0 open source?\n\nNo open-source release is listed for Clef. Vela 2.0 is open source (Apache-2.0 (weights, code and documentation). The 0.3B's tokeniser keeps the Gemma Terms of Use, and training data keeps its own licences).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/cloudflare-clef-vs-vela.json, and with the fewest tokens: https://www.anchorterminal.com/compare/cloudflare-clef-vs-vela.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"cloudflare-clef\", \"b\": \"vela\"}`.
