-A research agent is an AI system that autonomously searches the web, evaluates sources, chains multiple queries together (multi-hop retrieval), synthesizes findings, and produces cited reports. Systems like Perplexity, OpenAI Deep Research, and Google Gemini Deep Research demonstrate the power of this pattern.
