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-flash.** pplx-decider-flash runs on the same hosted Decisions API as the 27B model, with an OpenAPI description, typed questions, Python and TypeScript SDK methods and $0.01 per million input tokens, and its weights are public under Apache-2.0. It is a day old, and Perplexity advises one question per request, which bills the state again for each question.\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. Send images as base64 data URLs, which the guide and the reference both accept. Hosted HTTP(S) URLs are accepted per the reference only, and `file_id` is 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-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## Tutorials\n\n- [Route an invoice question with OpenAI Decisions](https://www.anchorterminal.com/tutorials/openai-decisions-api/), for OpenAI Decisions API\n\n## Questions\n\n### Which is better for AI agents, OpenAI Decisions API or pplx-decider-flash?\n\nOpenAI Decisions API scores 73.1 (BB) on agent readiness against pplx-decider-flash's 67.9 (B), and leads in 5 of 7 scored categories. pplx-decider-flash leads on reliability.\n\n### Which is cheaper for decision models, OpenAI Decisions API or pplx-decider-flash?\n\npplx-decider-flash, at free against $0.10 per 1M tokens for OpenAI Decisions API.
