Deep Research Agents

Agentic systems that decompose a complex query, iteratively search diverse sources, and synthesize a structured, cited report — distinct from single-shot QA; DRACO shows orchestration (Perplexity) beats the bare base model with tools, and factual accuracy is the weak axis. MisKnow-Agent puts a number on that weakness from the input side: one plausible-but-false document raises the false-conclusion adoption rate from 0% to 54.7%, with no instruction injection anywhere — and the same models that endorse those documents in-workflow unanimously flag them as misleading when handed them in isolation
