Google’s new Deep Research and Deep Research Max agents can search the web and your private data

Google on Monday unveiled the most significant upgrade to its autonomous research agent capabilities since the product's debut, launching two new agents — Deep Research and Deep Research Max — that for the first time allow developers to fuse open web data with proprietary enterprise information through a single API call , produce native charts and infographics inside research reports, and connect to arbitrary third-party data sources through the Model Context Protocol (MCP). The release, built on Google's Gemini 3.1 Pro model , marks an inflection point in the rapidly intensifying race to build AI systems that can autonomously conduct the kind of exhaustive, multi-source research that has traditionally consumed hours or days of human analyst time. It also represents Google's clearest bid yet to position its AI infrastructure as the backbone for enterprise research workflows in finance, life sciences, and market intelligence — industries where the stakes of getting information wrong are extraordinarily high. "We are launching two powerful updates to Deep Research in the Gemini API , now with better quality, MCP support, and native chart/infographics generation," Google CEO Sundar Pichai wrote on X. "Use Deep Research when you want speed and efficiency, and use Max when you want the highest quality context gathering & synthesis using extended test-time compute — achieving 93.3% on DeepSearchQA and 54.6% on HLE." Both agents are available starting today in public preview via paid tiers of the Gemini API , accessible through the Interactions API that Google first introduced in December 2025. Why Google built two research agents instead of one The launch introduces a tiered architecture that reflects a fundamental tension in AI agent design: the tradeoff between speed and thoroughness. Deep Research , the standard tier, replaces the preview agent Google released in December and is optimized for low-latency, interactive use cases. It delivers what Google d…
