This is a version of the tinyStories dataset augmented with 24000 new stories:
8000 containing an anaphoric pronoun (‘himself’, ‘herself’, ‘themself’, or ‘themselves’),
8000 containing the negative-polarity item (NPI) ‘ever’,
8000 containing both.
The new stories were generated by GPT-4o using prompts on the model of the original tinyStories generation prompts.
