Google Releases Deep Research & Max in Gemini API Preview

Google has moved Deep Research and Deep Research Max — autonomous research agents built on Gemini 3.1 Pro — into Gemini API public preview for paid users. The headline addition from the December preview is MCP server support: agents can now connect to enterprise data, internal repos, and private files alongside Google Search and Code Execution. Deep Research Max extends test-time compute and iterates on reports before returning. Inputs include PDF, CSV, images, audio, and video; native chart generation ships without external libraries.

Why It Matters

Enterprise AI research pipelines now have a Google-backed alternative to custom RAG stacks. Google Cloud enterprise availability is confirmed as coming soon.
