Deep Research Max Preview

by Google

Deep Research Max Preview is Google's higher-tier research-focused model, built for long-running, accuracy-critical investigations. It autonomously conducts multi-step research across many public web sources and synthesizes the findings into comprehensive, cited reports, using extended thinking for the harder reasoning steps. The model accepts text and images along with documents, so it can pull visual material into a research workflow, and it produces structured output for downstream use. With extended thinking and a 128k context window, it suits investigative tasks that demand depth, breadth of sourcing, and careful synthesis.
