Update
We have released a new dataset: anki-revlogs-10k.
Introduction
FSRS-Anki-20k is a dataset of 20k collections from Anki for FSRS project. It is a random sample of collections with 5000+ revlog entries, so it should contain a mix of older (still active) users, and newer users. Entries are pre-sorted in (cid, id) order.
There are two versions of the dataset: ./revlogs and ./dataset. The ./revlogs version contains the raw revlog entries, while the ./dataset version… See the full description on the dataset page: https://huggingface.co/datasets/open-spaced-repetition/FSRS-Anki-20k.SpaceOmicsBench-v3

Unmodified copies among Hugging Face Spaces
104,791 public Spaces that are copies of another Space, grouped into the
25,183 source histories they came from. Derived from a full census of the
1,458,692 public Spaces taken in August 2026.
This is not a similarity score. Members of a family are byte-identical
repositories, and the check below is what establishes that.

DeliChess
DeliChess is an English multi-party dialogue dataset for studying group
deliberation in chess puzzle solving. Participants first selected moves
independently, deliberated synchronously in groups, and then submitted revised
answers. The corpus contains 107 dialogues, 7,667 chat utterances, and 321
dialogue--puzzle cases. Its event stream also records the puzzle options and
paired pre-/post-deliberation choices.
Every genuine chat utterance has human annotations for… See the full description on the dataset page: https://huggingface.co/datasets/SpaceHunterInf/DeliChess.SpaceTravelersUniversalPlaylist

OR-Space
A full-lifecycle workspace benchmark for industrial optimization agents.
OR-Space evaluates whether LLM agents can do reliable operations research work
inside executable, multi-file workspaces. Each instance keeps business
requirements, parameter files, source code, solver artifacts, and evaluation
metadata as separate files, forcing the agent to recover and maintain the
optimization model through workspace interaction rather than one-shot text
generation.… See the full description on the dataset page: https://huggingface.co/datasets/YiYao7017/OR-Space.huggingface-spaces-datasetThis dataset provides information of all the spaces (~6,200 at time of snapshot) created on HuggingFace Spaces 🤗. Most of the data comes from a public API endpoint while some of the data is enriched by web scraping. The dataset is intended to provide a snapshot of the spaces and was last updated in first week of July-2022.
Along with the name of the space, the dataset consists of following columns:
