GPT Researcher¶

What it is¶

GPT Researcher (v4.0+, July 2026) is an autonomous agent designed for comprehensive online research on any given topic. It plans the research, browses the web, and synthesizes a final report with deep citations. It uses a "master-agent" and "research-agent" pattern to break down complex queries into manageable sub-tasks, now supporting multi-modal search and the MCP 3.0 Task Protocol.

What problem it solves¶

It automates the time-consuming process of manual research, gathering information from multiple sources and producing high-quality, grounded summaries. It specifically addresses LLM hallucinations by grounding every claim in a retrieved web source (via Tavily/SearXNG) and providing a verifiable bibliography.

Where it fits in the stack¶

Category: Agent / Research Automation. It serves as a specialized "Knowledge Acquisition" layer in an agentic stack, feeding structured data and reports into other agents or long-term memory stores like Letta.

Typical use cases¶

Market Research: Analyzing industry trends, competitor offerings, and financial reports.
Technical Deep Dives: Researching new software frameworks, hardware specifications, or architectural patterns.
Academic/Legal Preparation: Gathering sources, summaries, and case law for specific inquiries.
Daily Intelligence: Generating automated briefings on evolving news topics or specific market sectors.
Agentic Knowledge Base Population: Automatically generating documentation for new tools identified during a crawl.

Strengths¶

High Recall: Scrapes dozens of sources per task, far exceeding standard "search" tools or single-shot RAG.
Citation-First: Every report includes a comprehensive bibliography with direct links to sources.
Customizable: Allows defining specific "research tasks", tones, and report formats (PDF, Markdown, JSON).
Agentic Tooling: Native support for MCP 3.0, allowing it to be used as a tool by other agents like Claude 4.8 or Gemma 3.

Limitations¶

Cost: Scraping and synthesizing many sources can consume significant LLM tokens and API credits (Tavily).
Speed: A thorough research task can take several minutes to complete as it operates asynchronously across many sources.
Quality Dependency: Final report quality is heavily dependent on the quality of the underlying LLM used for synthesis and the search engine results.

When to use it¶

Exhaustive Research: When you need to gather information from dozens of sources simultaneously and summarize them into a single coherent report.
Fact-Checking: To verify information against current web data and receive a cited bibliography for verification.
Automated Long-Form Synthesis: When you need to create comprehensive, structured reports on complex topics without manual browsing.

When not to use it¶

Real-Time Fact Retrieval: For single-shot questions (e.g., "What is the capital of France?"), standard search tools or basic RAG are faster and cheaper.
Creative Writing: It is optimized for factual synthesis and technical reporting, not creative or conversational tasks.
Strict Budget Constraints: High token usage and search API costs make it expensive for high-volume, low-value tasks.

Getting started¶

Installation¶

pip install gpt-researcher

Environment Setup¶

export OPENAI_API_KEY='your-key'
export TAVILY_API_KEY='your-key'

Basic Usage¶

Run a research task via the Python API to generate a markdown report.

CLI examples¶

# Run a quick research report on a topic
python -m gpt_researcher.cli "Future of solid-state batteries in 2027" --report_type research_report

# Generate a detailed, in-depth report with a specific tone
python -m gpt_researcher.cli "Impact of MCP 3.0 on agentic ecosystems" --report_type detailed_report --tone analytical

# Conduct research filtered by specific domains
python -m gpt_researcher.cli "Latest SpaceX launches" --report_type research_report --query_domains spacex.com,nasa.gov

API examples¶

from gpt_researcher import GPTResearcher
import asyncio

async def main():
    # 1. Initialize the researcher with a specific query
    researcher = GPTResearcher(
        query="Evolution of agentic frameworks in July 2026",
        report_type="research_report",
        tone="technical"
    )

    # 2. Conduct research across multiple sources
    await researcher.conduct_research()

    # 3. Write and save the final report
    report = await researcher.write_report()
    with open("report.md", "w") as f:
        f.write(report)

if __name__ == "__main__":
    asyncio.run(main())
