How this price is scoped: Perplexity's own pricing page lists pplx-decider-v1.1-27b at $0.02 per 1M input tokens, output tokens Free, per-request fee None. You pay for input only: the content you send, every question and any images all count as input, so a request with 600 input tokens costs $0.000012. The $0 output here is Perplexity's published rate, not a missing number. The older pplx-decider-v1-27b still answers requests at the same $0.02; Perplexity halved the input price when v1.1 replaced it in October 2026, so a site still showing a higher Decisions API price is showing the old rate.
