Google DeepMind has officially launched two powerful new AI agents—Deep Research and Deep Research Max—designed to handle the heavy lifting of professional-grade investigations. Powered by the latest Gemini 3.1 Pro model, these tools mark a massive shift from simple web summarizers to fully autonomous researchers capable of writing structured, expert-level reports.
The announcement, made on April 21, 2026, positions Google as a leader in agentic workflows, where AI doesn’t just answer questions but actively navigates complex data across the web and private databases.
Speed vs. Depth: Two New Ways to Research
Google is offering two distinct versions of the agent to fit different professional needs:
- Deep Research: This version is built for speed and efficiency. It is designed for interactive use, providing quick, high-quality answers with low latency. It is the ideal choice for developers building research tools directly into apps where users need fast results.
- Deep Research Max: This is the heavyweight version designed for maximum depth. Instead of rushing, it uses more computing power to reason, search multiple times, and refine its findings. It is perfect for background work, like a nightly task that generates a full due diligence report for an analyst team by the next morning.
Breaking the Walled Garden of Data
One of the biggest upgrades is the support for the Model Context Protocol (MCP). This allows Deep Research to go beyond the open web.
- Proprietary Data: Businesses can securely connect the agent to their own private data streams, such as financial records or specialized market data.
- Multimodal Input: The agents can research using not just text, but also PDFs, images, audio, and video as context.
- Visual Reports: For the first time, Deep Research can natively generate charts and infographics within its reports, turning dense numbers into presentation-ready visuals.
Expert-Grade Fact Checking
Google has focused heavily on making these agents more reliable than standard chatbots. Deep Research Max is trained to consult a diverse range of sources—like SEC filings and peer-reviewed journals—and weigh conflicting evidence against each other. This ensures the final report isn’t just a summary, but a nuanced analysis that identifies critical details that older models might have missed.
To prove its real-world value, Google is already collaborating with major financial data providers like FactSet, S&P Global, and PitchBook to allow shared customers to pull expert data directly into their AI workflows.

Availability
Deep Research and Deep Research Max are available starting today in public preview for paid tiers of the Gemini API. Google also confirmed that these tools will soon be coming to Google Cloud for enterprise and startup customers.
