Performance Comparison

Model-evaluated generation quality metrics:

Tokenizer

We use a custom WordPiece tokenizer with a small vocabulary size of 4096. We conducted morphological analysis and coverage gain analysis on the dataset to build a small tokenizer without compromising on the quality of generation.

Dataset

The SimpleStories dataset is a collection of short stories generated by state-of-the-art language models. It features:

Story annotation with high-level concepts: theme, topic, style, etc.
Higher semantic and syntactic diversity through seeded story generation
Generated by 2024 models
Several NLP-metrics pre-computed to aid filtering
ASCII-only guarantee for the English dataset
