Sonar
Perplexity · 2025-02-11
Sonar is Perplexity's lightweight web-search language model, built on Llama 3.3 70B and released in February 2025 as an updated model for Perplexity's default search experience. It retrieves live internet data at query time and returns fast, citation-annotated answers, targeting use cases that need current information without the deeper multi-source retrieval of the Pro tier; Perplexity has not disclosed the derivative checkpoint's exact parameter count.
