MathLake: A Large-Scale Mathematics Dataset
MathLake is a massive collection of 8.3 million mathematical problems aggregated from over 50 open-source datasets. Unlike datasets focused on filtering for the highest quality solutions immediately, MathLake prioritizes query comprehensiveness, serving as a universal "raw ore" for researchers to curate, distill, or annotate further. The dataset provides annotations for Difficulty, Format, and Subject, covering diverse mathematical fields… See the full description on the dataset page: https://huggingface.co/datasets/OpenDataArena/MathLake.yelp-open-dataset-businessyelp-open-dataset-reviewsSYNTHETIC-1-SFT-Data-Code_decontaminated

Open Grant Data
756,453 U.S. funders · 95,735 grant opportunities · a 7,525,377-edge who-funds-whom
grant graph · 1,810,300 grantee organizations — public domain (CC0), embeddings included.
The open alternative to paywalled funder databases ($1,500–2,000/yr subscriptions). Built
entirely from public sources — IRS 990 / 990-PF filings, grants.gov, and state & foundation
portals — and released with modern embeddings so it's AI-ready out of the box.
