ODA-Math-460k
ODA-Math-460k is a large-scale math reasoning dataset curated from top-performing open mathematics corpora (selected via the OpenDataArena leaderboard) and refined through deduplication, benchmark decontamination, LLM-based filtering, and verifier-backed response distillation.It targets a “learnable but challenging” difficulty band: non-trivial for smaller models yet solvable by stronger reasoning models.

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.open-christian-data
Open Christian Data
Open Christian Data (OCD) aims to be the single unified collection of all public domain Christian text. It exists to bring this collection together from across the internet and to structure it in a useful format for public use.
Beyond the Bible, Christian writing is poorly represented as a cohesive dataset or as data structured for AI training. This Hugging Face release is the AI-focused publication of the collection: consistent, downloadable JSON for model… See the full description on the dataset page: https://huggingface.co/datasets/OpenChristianDataOrg/open-christian-data.
