# Open-Source DATAGEN Uses 8 Specialized Agents to Automate Data Science Reports

> An open-source multi-agent stack orchestrates hypothesis generation, code execution, visualization, and report writing under a LangGraph state machine with human review.

A new open-source project called [DATAGEN](https://github.com/starpig1129/DATAGEN) is picking up traction as a multi-agent research assistant that tries to automate the messy middle of data science work: forming hypotheses, cleaning data, writing analysis code, generating plots, searching literature, and drafting the report. It bills itself as an AI-powered platform that uses specialized agents for analysis, visualization, and reporting, built on LangChain, OpenAI GPT models, and LangGraph.

The repo has crossed 1.7k stars, ships under an MIT license, and is written entirely in Python. It was previously known as AI-Data-Analysis-MultiAgent before being rebranded.

## A crew of agents, not a monolith

Rather than running a single prompt-and-pray loop, DATAGEN splits the workflow across eight named agents, each with a scoped role:

* `hypothesis_agent` generates research hypotheses
* `process_agent` supervises the entire research process
* `visualization_agent` creates data visualizations
* `code_agent` writes data analysis code
* `searcher_agent` conducts literature and web searches
* `report_agent` writes research reports
* `quality_review_agent`
