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**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### 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### 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, OpenAI Decisions API or pplx-decider?\n\nOpenAI Decisions API scores 71.5 (BB) on agent readiness against pplx-decider's 62.9 (B), and leads in 5 of 7 scored categories. pplx-decider leads on reliability.\n\n### Which is cheaper for decision models, OpenAI Decisions API or pplx-decider?\n\npplx-decider, 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 pplx-decider need an API key?\n\nBoth need an API key.\n\n### Can an agent call OpenAI Decisions API and pplx-decider without installing anything?\n\nYes. OpenAI Decisions API has a hosted endpoint at https://api.openai.com/v1/decisions 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/openai-decisions-api-vs-pplx-decider.json, and with the fewest tokens: https://www.anchorterminal.com/compare/openai-decisions-api-vs-pplx-decider.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"openai-decisions-api\", \"b\": \"pplx-decider\"}`.
