  • DATAGEN is an open-source multi-agent research assistant with 1.7k GitHub stars, MIT licensed on GitHub.
  • Eight specialized agents cover hypothesis, code, visualization, search, reporting, quality review, and note-taking.
  • LangGraph state machine orchestrates the workflow with a human review gate before heavy processing.
  • Each agent can be pinned to a different provider: OpenAI, Anthropic, Google, Ollama, or Groq.
  • Progressive Disclosure architecture and MCP integration bring filesystem, GitHub, and Tavily web search.
  • Known weak spots include NoteTaker efficiency, total runtime, and potential in-place modification of input data.

A new open-source project called 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
