STORM (Stanford OVAL)
Leading#2 in Open sourcehigh confidence
Stanford's LLM knowledge-curation system (30.3k★) — researches a topic and generates a full-length, Wikipedia-style report with citations; Co-STORM adds human-in-the-loop.Our read
Why it ranks #2
The cited GitHub source records roughly 30.3k stars, and Stanford provenance plus inclusion in the Awesome Deep Research index give it a strong research-community signal.Here is the catch
Setup requires external model and retrieval services
Wikipedia-style output is not appropriate for every research deliverable
Runs can be slow, costly, and sensitive to retrieval quality
Does this well
Research design explicitly seeks diverse perspectives before drafting
Academic origin and published evaluation make the approach inspectable
Produces organized long-form reports with citations
