35 datasets

This category gathers general-purpose machine learning datasets. The UCI Machine Learning Repository, the KEEL repository and the Toronto Delve collection hold hundreds of tabular sets for classification and regression. Recommendation data comes from MovieLens, the Million Song Dataset, Yandex's Yambda-5B music interactions and eBay auction records. For video and vision there are YouTube-8M, YouTube-BoundingBoxes, the Audi Autonomous Driving Dataset, the TikTok dance dataset and the LLVIP low-light image pairs.

Newer entries measure AI systems themselves: model benchmark scores, free-tier limits of video models and local LLM inference speed and power use. Older academic sets are small and well studied, which makes them good for teaching but easy to overfit through repeated use. Check the licence on each: LLVIP is CC BY-NC, and MovieLens has its own usage terms that restrict commercial use. Some links point to Wayback or Kaggle mirrors because the original host is gone.

78 milestones in the history of artificial intelligence from 1943 to 2026, one row per event, from the McCulloch-Pitts neuron and the Turing test to current model releases and regulation. Each row has the date and how precisely it is known, the subject's common name, the person, lab or institution…

117 dated observations of what twelve AI video models grant on their free tiers, one row per figure. Each row carries the channel it was observed on, the date it was observed, and whether the source was a vendor statement or a report. Covered metrics include daily credit grants and daily generation…

Audi Autonomous Driving Dataseta2d2-dataset.github.io

We have published the Audi Autonomous Driving Dataset (A2D2) to support startups and academic researchers working on autonomous driving. Equipping a vehicle with a multimodal sensor suite, recording a large dataset, and labelling it, is time and labour intensive. Our dataset removes this high entry…

Weekly, hash-pinned point-in-time measurements of rising open-source and research-native AI systems, scored by momentum (the rate of change of their public signals) on a transparent, versioned public methodology. A system is marked rising only when two independent axes converge (development…

CC0Updated weekly2026–06-27/..

By releasing this dataset, we aim at providing a new testbed for computer vision techniques using Deep Learning. The main peculiarity is the shift from the domain of "natural images" proper of common benchmark datasets to biological imaging. We anticipate that the advantages of doing so could be…

CC BY-SA

Signed export of the GSPC board of AI behaviour measurements published by Council of AI (CSOAI Ltd). Scores come from deterministic grading on frozen item banks rather than LLM-as-judge, and the board is Ed25519-signed so any reader can re-check it client-side. Measurement, not certification.
