Multi-Agent Deep Researcher
Executive Summary
Enterprise teams often require deep research across multiple data sources to generate insights, technical documentation, or business intelligence. The Multi-Agent Deep Researcher is an AI-powered research automation system that orchestrates specialized AI agents to perform information retrieval, validation, and structured knowledge generation. By combining multi-agent collaboration with deep web search and real-time streaming responses, the solution delivers scalable and reliable research workflows while maintaining structured, citation-supported outputs.
Challenges
Solution Overview
The Multi-Agent Deep Researcher introduces a modular agentic architecture powered by CrewAI, enabling coordinated execution of specialized research agents. The system integrates OpenAI GPT models for reasoning and Linkup for deep web search capabilities. A FastAPI backend provides API-driven query submission and response handling, while Server-Sent Events enable real-time streaming of research progress and structured output generation.
How it Works
Query Submission via API Interface
Users submit research queries through the FastAPI /research endpoint.
Deep Web Information Retrieval
The Web Searcher agent performs deep search operations using Linkup, collecting relevant data sources and references.
Research Analysis and Validation
The Research Analyst agent processes collected data, removes redundancy, validates facts, and synthesizes key findings.
Structured Documentation Generation
The Technical Writer agent converts synthesized insights into structured markdown responses with citations.
Real-Time Streaming of Research Execution
The backend streams execution updates and final results using Server-Sent Events (SSE).
Context Passing Between Agents
Agents share intermediate outputs and contextual knowledge to maintain workflow continuity and improve result accuracy.
