What this fixes
A real fact is put to the model under the full cross product of the two
people's name lists, and counts as recognised if any one combination gets a
Yes. That is He et al.'s rule. Until 2026-08-26 the wrong answer it was
compared against was asked under one name per person, so the… See the full description on the dataset page: https://huggingface.co/datasets/latkes/factprobe-replication-negatives-allnames-v1.gz3d-aion-replication-attempt
GalaxyZoo 3D Segmentation Benchmark
An attempted replication of the GZ3D segmentation dataset used in section 7.2.3 in the AION-1. This dataset contains volunteer segmentations for the following channels: center, star, spiral, bar. It also contains the RGB images from Legacy Survey and the tokens from the AION-1 image tokenizer of the Legacy Survey image bands. Notably, these are pre–AION-1 transformer encoder, but post image-codec encoder/quantization. The reason why it's an… See the full description on the dataset page: https://huggingface.co/datasets/astronolan/gz3d-aion-replication-attempt.factprobe-replication-traj-b2-stage1-v1

Two prompts, put to gpt-5.1 for every subject surface form in the spouse

Correction, 2026-08-26
An earlier version of this card said the corpus states facts asymmetrically
in a way that tracks entity frequency, and gave 70.9% as the figure. That
number is right, and the generalisation drawn from it was wrong.
It holds for spouse and for no other relation. Recomputed across all four:
