🔎 GPT Researcher

GPT Researcher the first open deep research agent designed for both web and local research on any given task.

The agent produces detailed, factual, and unbiased research reports with citations. GPT Researcher provides a full suite of customization options to create tailor made and domain specific research agents. GPT Researcher goes well beyond RAG: planner and execution agents break each task into research questions, decision models keep only the context that is actually useful for answering them, multi-agent workflows coordinate specialized agents from planning to publication, and recursive deep research explores a topic in both breadth and depth. Research runs in parallel, which keeps it fast, stable and reliable, and reduces misinformation.

Our mission is to empower individuals and organizations with accurate, unbiased, and factual information through AI.

Why GPT Researcher?

• Objective conclusions for manual research can take weeks, requiring vast resources and time.
• LLMs trained on outdated information can hallucinate, becoming irrelevant for current research tasks.
• Current LLMs have token limitations, insufficient for generating long research reports.
• Limited web sources in existing services lead to misinformation and shallow results.
• Selective web sources can introduce bias into research tasks.

Architecture

The core idea is to utilize 'planner' and 'execution' agents. The planner generates research questions, while the execution agents gather relevant information. The publisher then aggregates all findings into a comprehensive report.

Steps:

• Create a task-specific agent based on a research query.
• Generate questions that collectively form an objective opinion on the task.
• Use a crawler agent for gathering information for each question.
• Summarize and source-track each resource.
• Filter and aggregate summaries into a final research report.

⚙️ Getting Started

Installation

1. Install Python 3.12 or later. Guide.

2. Clone the project and navigate to the directory:

   git clone https://github.com/assafelovic/gpt-researcher.git
   cd gpt-researcher
   

3. Set up API keys by exporting them or storing them in a .env file.

   export OPENAI_API_KEY={Your OpenAI API Key here}
   export TAVILY_API_KEY={Your Tavily API Key here}
   

   (Optional) For enhanced tracing and observability, you can also set:

   # export LANGCHAIN_TRACING_V2=true
   # export LANGCHAIN_API_KEY={Your LangChain API Key here}
   

   For custom OpenAI-compatible APIs (e.g., local models, other providers), you can also set:

   export OPENAI_BASE_URL={Your custom API base URL here}
   

4. Install dependencies and start the server:

   pip install -r requirements.txt
   python -m uvicorn main:app --reload
   

Visit http://localhost:8000 to start.

For other setups (e.g., Poetry or virtual environments), check the Getting Started page.

Run as PIP package

pip install gpt-researcher

Example Usage:

...
from gpt_researcher import GPTResearcher

query = "why is Nvidia stock going up?"
researcher = GPTResearcher(query=query)
# Conduct research on the given query
research_result = await researcher.conduct_research()
# Write the report
report = await researcher.write_report()
...

For more examples and configurations, please refer to the PIP documentation page.

🔧 MCP Client

GPT Researcher supports MCP integration to connect with specialized data sources like GitHub repositories, databases, and custom APIs. This enables research from data sources alongside web search.

export RETRIEVER=tavily,mcp  # Enable hybrid web + MCP research

from gpt_researcher import GPTResearcher
import asyncio
import os

async def mcp_research_example():
    # Enable MCP with web search
    os.environ["RETRIEVER"] = "tavily,mcp"
    
    researcher = GPTResearcher(
        query="What are the top open source web research agents?",
        mcp_configs=[
            {
                "name": "github",
                "command": "npx",
                "args": ["-y", "@modelcontextprotocol/server-github"],
                "env": {"GITHUB_TOKEN": os.getenv("GITHUB_TOKEN")}
            }
        ]
    )
    
    research_result = await researcher.conduct_research()
    report = await researcher.write_report()
    return report

🍌 Inline Image Generation

GPT Researcher can automatically generate and embed AI-created illustrations in your research reports using Google's Gemini models (Nano Banana).

# Enable in your .env file
IMAGE_GENERATION_ENABLED=true
GOOGLE_API_KEY=your_google_api_key
IMAGE_GENERATION_MODEL=models/gemini-2.5-flash-image

When enabled, the system will:

1. Analyze your research context to identify visualization opportunities
2. Pre-generate 2-3 relevant images during the research phase
3. Embed them inline as the report is written

Images are generated with dark-mode styling that matches the GPT Researcher UI, featuring professional infographic aesthetics with teal accents.

Learn more about Image Generation in our documentation.

✨ Deep Research

GPT Researcher now includes Deep Research - an advanced recursive research workflow that explores topics with agentic depth and breadth. This feature employs a tree-like exploration pattern, diving deeper into subtopics while maintaining a comprehensive view of the research subject.

• 🌳 Tree-like exploration with configurable depth and breadth
• ⚡️ Concurrent processing for faster results
• 🤝 Smart context management across research branches
• ⏱️ Takes ~5 minutes per deep research
• 💰 Costs ~$0.4 per research (using o3-mini on "high" reasoning effort)

Learn more about Deep Research in our documentation.

🎯 Smart Context Filtering with Jev

Every research run scrapes dozens of pages, and only some of each page helps answer the question. Before anything reaches the LLM, GPT Researcher decides which passages to keep. By default it uses Jev by TypeSafe, a model that scores how useful each passage is for the question, rather than how similar its words or embedding are.

Jev's context is 59% more relevant than embeddings, at the same cost (73% of kept passages relevant vs 46%). We benchmarked every option on 28 research tasks, replaying the same scraped sources so that only the filter changed:

Writing the report takes ~45s whichever filter you use, so a run's total time moves only by the filter step. Passing every page unfiltered writes the broadest reports on open-ended questions, but costs 65% more.

Nothing is required. With a TYPESAFE_API_KEY, Jev is used. Without one, or if a Jev call fails, GPT Researcher falls back to keyword (BM25) ranking, which runs locally with no API key, model or embeddings. Embeddings remain available as an option.
