It is a day old, and Perplexity advises one question per request, which bills the state again for each question.\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### pplx-decider-flash\n\n1. Send `Authorization: Bearer` with `model` set to `pplx-decider-flash-v1.2`. A key in `x-api-key` returns 401.\n2. Send one question per request by default. Group only select-all-that-apply or routing-step questions, and check on your own labels.\n3. Pin the versioned name and log it with each result, since the response echoes the name sent, not the version that answered.\n4. Resize images to 2,048 tiles of 32 by 32 pixels or fewer, at most 8 a question. Larger images end in a 504 after about a minute.\n5. Compare it with `pplx-decider-v1.2` on a labelled sample at your thresholds before choosing 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## Tutorials\n\n- [Find contact details in a message with Vela](https://www.anchorterminal.com/tutorials/vela/), for Vela 2.0\n\n## Questions\n\n### Which is better for AI agents, pplx-decider-flash or Vela 2.0?\n\npplx-decider-flash scores 67.9 (B) on agent readiness against Vela 2.0's 66.5 (B), and leads in 5 of 7 scored categories.
