Deep Research refers to AI research agent systems developed by multiple organizations that autonomously gather and synthesize information from online sources to complete complex research tasks. Google's Test-Time Diffusion Deep Researcher models report writing as an iterative refinement process and achieved a 74.5% win rate against OpenAI's Deep Research, while Anthropic released its own Deep Research tool to Pro tier users with documented safety evaluations. An open-source reproduction of OpenAI's Deep Research system has also been made available, enabling local deployment with custom models.
