The dataset repositories do not include a separate full LICENSE file or a dataset-specific copyright line. The full MIT notice below is reproduced verbatim from the publisher's associated benchmarking software repository, preserving its copyright notice:
https://github.com/arcprize/arc-agi-benchmarking/blob/main/LICENSE.md
Git blob SHA: f94666d740815278ab7c9e6074eaaf3660d5f929
The data reuse basis is each dataset's own explicit MIT declaration, not a claim that the software license alone licenses all data.
