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### SPEV\n\n1. Send `model: \"spev\"` to `POST https://api.sprag.ai/v1/decisions` with a bearer key. `/v1/systemone` returns 410\n2. Ask every question about one piece of evidence in one request. Answers come back in question order\n3. Send audio as base64 in `input_audio` with `format`, not as a data URL, and at most one image across all messages\n4. Keep evidence and questions under 8,192 tokens. Over the limit returns 400 `model_limit_exceeded`\n5. Back off on 429 and 503 for `Retry-After` seconds. Limits are 60 requests a minute per organisation by default\n6. Handle an answer of type `refusal`, which carries no probabilities\n\n## Questions\n\n### Which is better for AI agents, pplx-decider-flash or SPEV?\n\npplx-decider-flash scores 67.9 (B) on agent readiness against SPEV's 51.1 (D), and leads in 6 of 7 scored categories. SPEV leads on payments \u0026 pricing.\n\n### Do pplx-decider-flash and SPEV need an API key?\n\nBoth need an API key.\n\n### Can an agent call pplx-decider-flash and SPEV without installing anything?\n\nYes. pplx-decider-flash has a hosted endpoint at https://api.perplexity.ai/v1/decisions and SPEV at https://api.sprag.ai/v1/decisions.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/pplx-decider-flash-vs-sprag-spev.json, and with the fewest tokens: https://www.anchorterminal.com/compare/pplx-decider-flash-vs-sprag-spev.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"pplx-decider-flash\", \"b\": \"sprag-spev\"}`.
