Perplexity Decider Flash v1.2

What you can use today

Token prices measure the small pieces of text the model reads or produces. Capacity is the amount the service accepts in a request; check the limits below for any fallback to another model. A dash means the rate is unverified.

Exact provider API ID: pplx-decider-flash-v1.2. Each question is answered separately, even when several are sent in one request. Start with one question per request; other questions do not share one inference pass.

Use pplx-decider-flash-v1.2 for the current version or pplx-decider-flash-latest to follow future updates. Revalidate your probability thresholds after a version change. Gateway also lists perplexity/pplx-decider-flash-v1.2. Its zero output-limit placeholder is not a verified limit on answers. The native default is 10 requests per second per organization shared across both models, plus 4 million tokens per minute and 240 million per hour for this model. Higher limits require contacting Perplexity.

The native limit is fewer than 256K tokens for the shared information, images and each question. Large multi-question requests can be split. Up to 128 questions, 255 choice options, 10 score levels and a 32 MiB request body. Gateway’s 262,144 declaration is separate.
