Free (rate-limited)
Perplexity Decider V1.3 is free on OpenRouter for classification and routing
Decider V1.3 and Decider Flash V1.3 are free for a limited time on OpenRouter, via the Decisions API, for classification, routing, and scoring
Perplexity’s Decider V1.3 and the lighter Decider Flash V1.3 now have free routes on OpenRouter. They are decision models for classification, routing, and scoring, not chat models. Calls go through the Decisions API, not the usual chat-completions endpoint. Both models support about 262,000 tokens of context and can read images. The free endpoints are rate-limited, and no end date has been announced.
- Eligibility
- An OpenRouter account is enough to call them. These models only work through the Decisions API, not the usual chat-completions endpoint. OpenRouter’s EU in-region routing is not available. The free endpoints are rate-limited.
- Benefit duration
- Free for a limited time; no end date has been announced
The briefing
Perplexity’s Decider V1.3 and the lighter Decider Flash V1.3 now have free routes on OpenRouter. They are not chat models and do not generate token-by-token replies. Instead they read the content you send and return typed, probabilistic answers to a set of questions, which makes them a good fit for classification, routing, moderation, and scoring. Flash is distilled from V1.3, shares the same API contract, and is better for high-volume, latency-sensitive work.
What you get
The OpenRouter model IDs are perplexity/pplx-decider-v1.3:free and perplexity/pplx-decider-flash-v1.3:free. Both models support about 262,000 tokens of context and can read text and images. Requests go to https://openrouter.ai/api/alpha/decisions; ordinary chat-completions SDKs will not work.
The free endpoints allow up to 20 requests per minute. Accounts that have purchased fewer than 10 credits get up to 50 requests per day; after at least 10 credits have been purchased, the daily cap rises to 1,000. No end date has been announced. OpenRouter’s EU in-region routing is not available. The same models on Vercel AI Gateway are pay-per-use at $0.02 and $0.01 per million input tokens, with no free route.
