GPT Researcher - Autonomous AI Research Agent

# GPT Researcher > GPT Researcher is an open-source autonomous AI research agent that conducts comprehensive deep research on any topic, gathers information from dozens of trusted sources in parallel, and produces long-form research reports with inline citations. It is the #1-ranked deep-research system on Carnegie Mellon University's DeepResearchGym benchmark and powers production research workflows for thousands of teams. ## What it is - An autonomous agent (not a chatbot) that plans, searches, validates, and writes. - Pluggable across LLMs (OpenAI, Anthropic, Google, Mistral, DeepSeek, local models via Ollama, LiteLLM) and search providers (Tavily, Bing, Google, DuckDuckGo, SearXNG, etc.). - Open source under MIT, available as a Python package, a self-hosted FastAPI server, a Docker image, and an MCP (Model Context Protocol) server. - Designed to be embedded inside other agents, IDEs, and workflows. ## When to use it - When a single LLM call or web-search tool is not enough and you need a *researched* answer with sources. - When you need long-form reports (executive summaries, market analyses, due-diligence briefs, literature reviews) generated end-to-end. - When an LLM agent (Claude, ChatGPT, Cursor, custom) needs a "deep research" sub-tool to fetch grounded, cited context. - When you want full control over the LLM, search engine, and data sources (including private / internal docs). ## Primary capabilities - `deep_research` - autonomous multi-source research with planning, source validation, and citation tracking. - `quick_search` - low-latency web search with snippets across any GPT Researcher-supported retriever. - `write_report` - generate long-form research reports from accumulated research context. - `get_research_sources` - list all sources gathered during a research run. - `get_research_context` - return the full accumulated research context. - Streaming output via WebSockets and Server-Sent Events. ## Use cases - Investment & equity research (c
