Google's next-generation autonomous research agent that represents a step change for AI-powered research capabilities.
Deep Research Max is an autonomous AI research agent from Google that conducts multi-step, long-horizon research tasks and produces comprehensive synthesized reports, available through Gemini with a freemium tier and higher quotas on paid Google AI plans. It is designed for analysts, researchers, students, and knowledge workers who need depth rather than quick answers.
Announced on April 21, 2026 by Google researchers Lukas Haas and Srinivas Tadepalli, Deep Research Max represents the next generation of Google's Deep Research agents and is built on the Gemini 3.1 Pro model family. Unlike a standard chatbot turn, the agent plans a research brief, searches and browses the open web, evaluates source credibility, and iteratively refines its plan before writing a long-form report with citations. The "Max" tier extends runtime, reasoning depth, and the number of sources the agent is willing to explore, which Google positions as a step change in autonomous research quality over the original Deep Research released in late 2024.
