stories_by_complexityA JSON formatted dataset comprising 31156 short stories for children aged 4 to 16.
This dataset is synthetic and is created using GPT4.
In addition to a story title, summary, and story text, I have included elements such genre, voicing, tense of the story as well as extra information about the age-appropriateness of the story themes (as determined by GPT4), and several text complexity metrics.
The text complexity metrics (Flesch-Kincaid, Gunning Fog Index, SMOG Index, Automated Readability… See the full description on the dataset page: https://huggingface.co/datasets/BoltMonkey/stories_by_complexity.llm-query-complexity-benchmark
LLM Query Complexity Benchmark
A multi-domain, perfectly balanced dataset of 6,000 labeled queries (4,800 train / 1,200 test) for training and evaluating LLM query complexity classifiers that route queries to the most cost-effective inference tier.
Built for the STREAM project (Smart Tiered Routing Engine for AI Models), which routes queries automatically between local CPU models, institutional HPC GPU clusters, and cloud API tiers.

Complexity Kink Research: LLM Code Generation Benchmark
First published: February 22, 2026Author: Michael Hernandez (XxCotHGxX)GitHub: XxCotHGxX/ComplexityKinkLicense: CC BY 4.0
Overview
This dataset supports the Complexity Kink research program — an econometric investigation into whether large language models exhibit a structural performance discontinuity as a function of problem complexity.
The central hypothesis is that LLM code generation performance does not… See the full description on the dataset page: https://huggingface.co/datasets/XxCotHGxX/complexity-kink-research.word_count_word_complexityhan-domestic-task-complexity-annotations-v1
