What it is

STORM is a research system built on large language models. Given a topic, it searches the internet, simulates conversations to gather information, builds an outline, and writes a full-length article with citations. Co-STORM extends it so a human can take part in the discussion and steer the research. The README says the output is not publication-ready and often needs significant editing, but experienced Wikipedia editors have found it useful for pre-writing.

  • Generate a Wikipedia-style draft article on a topic with citations from internet sources
  • Run STORM's research stage only, then reuse the saved results for later writing
  • Use Co-STORM to explore a topic in a discussion with AI experts and a moderator
  • Ground the research on your own documents using the VectorRM retriever

Great for

  • Developers who want to build a customizable research or report-writing pipeline
  • Writers who want a first-draft outline and source list before writing
  • Researchers exploring a new topic who want a structured overview with references
  • Teams experimenting with different language models and search engines

Not ideal for

  • Anyone needing publication-ready text, since the README says articles often need significant edits
  • People without an API key for a language model or search provider, since the system depends on them
  • Users who need a finished no-setup app, since the README centers on a Python package and code setup

How to get it

  1. 1

    Install with a package manager

    You'll need: Python 3.11 (per the README's conda example) · Conda or another Python environment manager · API keys for a language model provider and a search provider

    Install the library from PyPI

    pip install knowledge-storm

    Clone the repository for source install

    git clone https://github.com/stanford-oval/storm.git

    Create a Python 3.11 environment

    conda create -n storm python=3.11

    Install requirements from source

    pip install -r requirements.txt
  2. 2

    Run it

    • Install the package with pip install knowledge-storm
    • Set your language model API key (for example OPENAI_API_KEY) and search API key (for example YDC_API_KEY) as environment variables
    • Create a STORMWikiLMConfigs object and a retrieval module such as YouRM
    • Create a STORMWikiRunner and call run with a topic
    • Call post_run and summary to review the results
  3. 3

    Get the most out of it

    • Use a cheaper model for conversation simulation and a stronger model for article generation, as the README suggests
    • Try different retrievers such as BingSearch, VectorRM for your own documents, or DuckDuckGoSearchRM
    • Use the do_research flag to reuse saved research results instead of repeating searches
    • Try Co-STORM to add your own input to the discussion and build a mind map of the topic
    • Check the STORMWikiRunnerArguments class for more configuration options

Strengths

  • Modular design: language models and search engines can be swapped, per the README's litellm and retriever support
  • Produces outlines and cited text rather than a single unsourced answer
  • Open source under the MIT license with an active research and release history

Trade-offs

  • The README says output is not publication-ready and often needs significant editing
  • Requires configured language model and search API keys, which may carry costs
  • Installation and customization assume Python and some comfort with code
