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**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### 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### 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, OpenAI Decisions API or Vela 2.0?\n\nOpenAI Decisions API scores 71.5 (BB) on agent readiness against Vela 2.0's 66.5 (B), and leads in 4 of 7 scored categories. Vela 2.0 leads on payments \u0026 pricing and maintenance \u0026 community.\n\n### Which is cheaper for inference decision, OpenAI Decisions API or Vela 2.0?\n\nVela 2.0, at free against $0.10 per 1M tokens for OpenAI Decisions API. These are the vendors' published prices for the job.\n\n### Do OpenAI Decisions API and Vela 2.0 need an API key?\n\nOpenAI Decisions API needs an API key. Vela 2.0 needs no key.\n\n### Can an agent call OpenAI Decisions API and Vela 2.0 without installing anything?\n\nOpenAI Decisions API has a hosted endpoint at https://api.openai.com/v1/decisions. No hosted endpoint is listed for Vela 2.0.\n\n### Are OpenAI Decisions API and Vela 2.0 open source?\n\nNo open-source release is listed for OpenAI Decisions API. 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/openai-decisions-api-vs-vela.json, and with the fewest tokens: https://www.anchorterminal.com/compare/openai-decisions-api-vs-vela.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"openai-decisions-api\", \"b\": \"vela\"}`.
