While the system cannot produce publication-ready articles that often require a significant number of edits, experienced Wikipedia editors have found it helpful in their pre-writing stage.

More than 70,000 people have tried our live research preview. Try it out to see how STORM can help your knowledge exploration journey and please provide feedback to help us improve the system 🙏!

STORM breaks down generating long articles with citations into two steps:

1. Pre-writing stage: The system conducts Internet-based research to collect references and generates an outline.
2. Writing stage: The system uses the outline and references to generate the full-length article with citations.

STORM identifies the core of automating the research process as automatically coming up with good questions to ask. Directly prompting the language model to ask questions does not work well. To improve the depth and breadth of the questions, STORM adopts two strategies:

1. Perspective-Guided Question Asking: Given the input topic, STORM discovers different perspectives by surveying existing articles from similar topics and uses them to control the question-asking process.
2. Simulated Conversation: STORM simulates a conversation between a Wikipedia writer and a topic expert grounded in Internet sources to enable the language model to update its understanding of the topic and ask follow-up questions.

Co-STORM proposes a collaborative discourse protocol which implements a turn management policy to support smooth collaboration among

• Co-STORM LLM experts: This type of agent generates answers grounded on external knowledge sources and/or raises follow-up questions based on the discourse history.
• Moderator: This agent generates thought-provoking questions inspired by information discovered by the retriever but not directly used in previous turns. Question generation can also be grounded!
• Human user: The human user will take the initiative to either (1) observe the discourse to gain deeper understanding of the topic, or (2) actively engage in the conversation by injecting utterances to steer the discussion focus.

Co-STORM also maintains a dynamic updated mind map, which organize collected information into a hierarchical concept structure, aiming to build a shared conceptual space between the human user and the system. The mind map has been proven to help reduce the mental load when the discourse goes long and in-depth.

Both STORM and Co-STORM are implemented in a highly modular way using dspy.

To install the knowledge storm library, use pip install knowledge-storm.

You could also install the source code which allows you to modify the behavior of STORM engine directly.

1. Clone the git repository.

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

2. Install the required packages.

   conda create -n storm python=3.11
   conda activate storm
   pip install -r requirements.txt

Currently, our package support:

• OpenAIModel, AzureOpenAIModel, ClaudeModel, VLLMClient, TGIClient, TogetherClient, OllamaClient, GoogleModel, DeepSeekModel, GroqModel as language model components
• YouRM, BingSearch, VectorRM, SerperRM, BraveRM, SearXNG, DuckDuckGoSearchRM, TavilySearchRM, GoogleSearch, and AzureAISearch as retrieval module components

🌟 PRs for integrating more language models into knowledge_storm/lm.py and search engines/retrievers into knowledge_storm/rm.py are highly appreciated!

Both STORM and Co-STORM are working in the information curation layer, you need to set up the information retrieval module and language model module to create their Runner classes respectively.

The STORM knowledge curation engine is defined as a simple Python STORMWikiRunner class. Here is an example of using You.com search engine and OpenAI models.

import os
from knowledge_storm import STORMWikiRunnerArguments, STORMWikiRunner, STORMWikiLMConfigs
from knowledge_storm.lm import OpenAIModel
from knowledge_storm.rm import YouRM

lm_configs = STORMWikiLMConfigs()
openai_kwargs = {
    'api_key': os.getenv("OPENAI_API_KEY"),
    'temperature': 1.0,
    'top_p': 0.9,
}
# STORM is a LM system so different components can be powered by different models to reach a good balance between cost and quality.
# For a good practice, choose a cheaper/faster model for `conv_simulator_lm` which is used to split queries, synthesize answers in the conversation.
# Choose a more powerful model for `article_gen_lm` to generate verifiable text with citations.
gpt_35 = OpenAIModel(model='gpt-3.5-turbo', max_tokens=500, **openai_kwargs)
gpt_4 = OpenAIModel(model='gpt-4o', max_tokens=3000, **openai_kwargs)
lm_configs.set_conv_simulator_lm(gpt_35)
lm_configs.set_question_asker_lm(gpt_35)
lm_configs.set_outline_gen_lm(gpt_4)
lm_configs.set_article_gen_lm(gpt_4)
lm_configs.set_article_polish_lm(gpt_4)
# Check out the STORMWikiRunnerArguments class for more configurations.
engine_args = STORMWikiRunnerArguments(...)
rm = YouRM(ydc_api_key=os.getenv('YDC_API_KEY'), k=engine_args.search_top_k)
runner = STORMWikiRunner(engine_args, lm_configs, rm)

The STORMWikiRunner instance can be evoked with the simple run method:

topic = input('Topic: ')
runner.run(
    topic=topic,
    do_research=True,
    do_generate_outline=True,
    do_generate_article=True,
    do_polish_article=True,
)
runner.post_run()
runner.summary()

• do_research: if True, simulate conversations with difference perspectives to collect information about the topic; otherwise, load the results.
• do_generate_outline: if True, generate an outline for the topic; otherwise, load the results.
• do_generate_article: if True, generate an article for the topic based on the outline and the collected information; otherwise, load the results.
• do_polish_article: if True, polish the article by adding a summarization section and (optionally) removing duplicate content; otherwise, load the results.

The Co-STORM knowledge curation engine is defined as a simple Python CoStormRunner class. Here is an example of using Bing search engine and OpenAI models.

from knowledge_storm.collaborative_storm.engine import CollaborativeStormLMConfigs, RunnerArgument, CoStormRunner
from knowledge_storm.lm import OpenAIModel
from knowledge_storm.logging_wrapper import LoggingWrapper
from knowledge_storm.rm import BingSearch

# Co-STORM adopts the same multi LM system paradigm as STORM 
lm_config: CollaborativeStormLMConfigs = CollaborativeStormLMConfigs()
openai_kwargs = {
    "api_key": os.getenv("OPENAI_API_KEY"),
    "api_provider": "openai",
    "temperature": 1.0,
    "top_p": 0.9,
    "api_base": None,
} 
question_answering_lm = OpenAIModel(model=gpt_4o_model_name, max_tokens=1000, **openai_kwargs)
discourse_manage_lm = OpenAIModel(model=gpt_4o_model_name, max_tokens=500, **openai_kwargs)
utterance_polishing_lm = OpenAIModel(model=gpt_4o_model_name, max_tokens=2000, **openai_kwargs)
warmstart_outline_gen_lm = OpenAIModel(model=gpt_4o_model_name, max_tokens=500, **openai_kwargs)
question_asking_lm = OpenAIModel(model=gpt_4o_model_name, max_tokens=300, **openai_kwargs)
knowledge_base_lm = OpenAIModel(model=gpt_4o_model_name, max_tokens=1000, **openai_kwargs)

lm_config.set_question_answering_lm(question_answering_lm)
lm_config.set_discourse_manage_lm(discourse_manage_lm)
lm_config.set_utterance_polishing_lm(utterance_polishing_lm)
lm_config.set_warmstart_outline_gen_lm(warmstart_outline_gen_lm)
lm_config.set_question_asking_lm(question_asking_lm)
lm_config.set_knowledge_base_lm(knowledge_base_lm)

# Check out the Co-STORM's RunnerArguments class for more configurations.
topic = input('Topic: ')
runner_argument = RunnerArgument(topic=topic, ...)
logging_wrapper = LoggingWrapper(lm_config)
bing_rm = BingSearch(bing_search_api_key=os.environ.get("BING_SEARCH_API_KEY"),
                     k=runner_argument.retrieve_top_k)
costorm_runner = CoStormRunner(lm_config=lm_config,
                               runner_argument=runner_argument,
                               logging_wrapper=logging_wrapper,
                               rm=bing_rm)

The CoStormRunner instance can be evoked with the warmstart() and step(...) methods.

# Warm start the system to build shared conceptual space between Co-STORM and users
costorm_runner.warm_start()

# Step through the collaborative discourse 
# Run either of the code snippets below in any order, as many times as you'd like
# To observe the conversation:
conv_turn = costorm_runner.step()
# To inject your utterance to actively steer the conversation:
costorm_runner.step(user_utterance="YOUR UTTERANCE HERE")

# Generate report based on the collaborative discourse
costorm_runner.knowledge_base.reorganize()
article = costorm_runner.generate_report()
print(article)

We provide scripts in our examples folder as a quick start to run STORM and Co-STORM with different configurations.

We suggest using secrets.toml to set up the API keys. Create a file secrets.toml under the root directory and add the following content:

# Set up OpenAI API key.
OPENAI_API_KEY="your_openai_api_key"
# If you are using the API service provided by OpenAI, include the following line:
OPENAI_API_TYPE="openai"
# If you are using the API service provided by Microsoft Azure, include the following lines:
OPENAI_API_TYPE="azure"
AZURE_API_BASE="your_azure_api_base_url"
AZURE_API_VERSION="your_azure_api_version"
# Set up You.com search API key.
YDC_API_KEY="your_youcom_api_key"

To run STORM with gpt family models with default configurations:

Run the following command.

python examples/storm_examples/run_storm_wiki_gpt.py \
    --output-dir $OUTPUT_DIR \
    --retriever you \
    --do-research \
    --do-generate-outline \
    --do-generate-article \
    --do-polish-article

To run STORM using your favorite language models or grounding on your own corpus: Check out examples/storm_examples/README.md.

To run Co-STORM with gpt family models with default configurations,

1. Add BING_SEARCH_API_KEY="xxx" and ENCODER_API_TYPE="xxx" to secrets.toml
2. Run the following command

python examples/costorm_examples/run_costorm_gpt.py \
    --output-dir $OUTPUT_DIR \
    --retriever bing

If you have installed the source code, you can customize STORM based on your own use case. STORM engine consists of 4 modules:

1. Knowledge Curation Module: Collects a broad coverage of information about the given topic.
2. Outline Generation Module: Organizes the collected information by generating a hierarchical outline for the curated knowledge.
3. Article Generation Module: Populates the generated outline with the collected information.
4. Article Polishing Module: Refines and enhances the written article for better presentation.

The interface for each module is defined in knowledge_storm/interface.py, while their implementations are instantiated in knowledge_storm/storm_wiki/modules/*. These modules can be customized according to your specific requirements (e.g., generating sections in bullet point format instead of full paragraphs).

If you have installed the source code, you can customize Co-STORM based on your own use case

1. Co-STORM introduces multiple LLM agent types (i.e. Co-STORM experts and Moderator). LLM agent interface is defined in knowledge_storm/interface.py , while its implementation is instantiated in knowledge_storm/collaborative_storm/modules/co_storm_agents.py. Different LLM agent policies can be customized.
2. Co-STORM introduces a collaborative discourse protocol, with its core function centered on turn policy management. We provide an example implementation of turn policy management through DiscourseManager in knowledge_storm/collaborative_storm/engine.py. It can be customized and further improved.

To facilitate the study of automatic knowledge curation and complex information seeking, our project releases the following datasets:

The FreshWiki Dataset is a collection of 100 high-quality Wikipedia articles focusing on the most-edited pages from February 2022 to September 2023. See Section 2.1 in STORM paper for more details.

You can download the dataset from huggingface directly. To ease the data contamination issue, we archive the source code for the data construction pipeline that can be repeated at future dates.

To study users’ interests in complex information seeking tasks in the wild, we utilized data collected from the web research preview to create the WildSeek dataset. We downsampled the data to ensure the diversity of the topics and the quality of the data. Each data point is a pair comprising a topic and the user’s goal for conducting deep search on the topic. For more details, please refer to Section 2.2 and Appendix A of Co-STORM paper.

The WildSeek dataset is available here.

For STORM paper experiments, please switch to the branch NAACL-2024-code-backup here.

For Co-STORM paper experiments, please switch to the branch EMNLP-2024-code-backup (placeholder for now, will be updated soon).

Our team is actively working on:

1. Human-in-the-Loop Functionalities: Supporting user participation in the knowledge curation process.
2. Information Abstraction: Developing abstractions for curated information to support presentation formats beyond the Wikipedia-style report.

If you have any questions or suggestions, please feel free to open an issue or pull request. We welcome contributions to improve the system and the codebase!
