Language model · January 2025
Perplexity Sonar Pro extends the Sonar call to a 200K-token context while remaining without a dedicated reasoning mode in the original Chat Completions model. Compared with Sonar, it remains a hosted search-and-answer service.

pplx-decider-v1-27b is Perplexity’s 27-billion-parameter checkpoint for decisions over a state. The Decisions API accepts text, JSON, and images, then asks through a fixed schema for Choice, Noul, or Score. The result contains probabilities and confidence instead of a free-form answer.
