Deep Research Agents
Autonomous agents that iteratively search, read, reason, and synthesize multi-source, cited reports on a question over many steps.
Deep research agents interleave web search, retrieval, and reasoning across many turns to produce cited, report-style answers, typically trained with agentic RL.
They became a distinct product and research category in 2025, evaluated on benchmarks like DeepResearch Bench for report fidelity and citation accuracy.
