How Perplexity AI Works
Perplexity AI uses a unique combination of LLMs and search engine infrastructure. When a user enters a query, it scans the web in real-time, synthesizes information from authoritative sources, and generates a response in natural language. Unlike traditional search engines, it does not give a list of links—it gives direct, cited answers.
?? Integrated with GPT-3.5, GPT-4, and Claude for natural conversations
