## Definition

Deep Research is an agentic AI capability that autonomously browses the web, synthesizes hundreds of sources, and produces a cited analyst-level report from a single prompt. The agent iterates — searching, reading, pivoting — for 5-30 minutes before delivering structured output.

Google [launched the first Deep Research product on December 11, 2024](https://techcrunch.com/2024/12/11/gemini-can-now-research-deeper/) inside Gemini Advanced; OpenAI followed on [February 3, 2025](https://openai.com/index/introducing-deep-research/) with a version powered by a specialized o3 model that scored 26.6% on Humanity's Last Exam. Perplexity, Anthropic, and Mistral subsequently shipped their own variants, turning the phrase into a contested product category.

## Analogy

Think of it as hiring a research analyst who never sleeps, reads 200 tabs at once, and delivers a memo in 20 minutes.

## Why it's emerging now

Google's Deep Research Max (April 21, 2026) introduced MCP integration for private enterprise data, upgrading the category from web-only to hybrid public+private research. Same week, Almanac MCP turned Claude Code into a Deep Research agent and Gemini's agents gained both web and private data search — the category crossed from consumer novelty into enterprise workflow infrastructure.
