Gemini Deep Research Agent
The best research agent is open for devs
Visit website →About
The Gemini Deep Research Agent is Google's research agent, made available to developers through the Interactions API. Given a question, it plans a line of investigation, searches and reads across many sources, follows up on gaps, and synthesises a structured report with citations, working autonomously through the multi-step process.
It is powered by Gemini 3 Pro and is meant for questions that need breadth and cross-referencing rather than a single lookup, such as market scans, literature reviews, and due diligence.
It is aimed at developers building research features into their own products, and at teams that want programmatic access to deep research rather than running each query by hand in a chat app.

Why we picked it
This is Google's own research agent opened up through the Interactions API for developers to build with, not just use — worth including for teams that want Gemini 3 Pro's multi-step research and citation synthesis inside their own product.
