PPLX Decider v1 (27B)

perplexity/pplx-decider-v1-27b is Perplexity's decision model on its new Decisions API. Send state and typed questions (noul / choice / score) to POST /api/v1/decisions and get back a probability distribution over a fixed set of answers — probabilities, not written text, so it generates no free-form output. Perplexity scores it at 85.71% across 11 decision benchmarks. It has a 262,144-token input limit, and state may be a string, an object, or an array of OpenAI-style image_url parts carrying base64 PNG/JPEG/WebP data URLs, so it scores images too.

• Terminal — anyr decision --model perplexity/pplx-decider-v1-27b (Decisions app).
• App code — plain fetch to /api/v1/decisions, see the example below.

PPLX Decider v1 (27B) is **BYOK-only**, reached through Perplexity itself — the model is not listed on OpenRouter or any other aggregator we route. Add a Perplexity key under Dashboard → BYOK; AnyRouter charges nothing for a BYOK route, and Perplexity bills $0.04 per million input tokens with output tokens free.
