A dataset from OpenAI containing 250K WebText documents alongside 250K samples each from four GPT-2 model sizes, both untruncated and Top-K 40 truncated, with train/valid/test splits. It includes download scripts and a detection baseline to support research on detecting model-generated text and studying biases.

Use cases

• train a classifier to detect GPT-2 generated text
• research biases in language model outputs
• benchmark AI-generated text detection methods
• study how model size affects detectability of samples
• get human vs machine text pairs for NLP experiments
• research adversarial evasion of text detectors

When to choose

• you need labeled human vs GPT-2 text for detection research
• you want a large-scale benchmark for machine-generated text studies
• you're studying properties of GPT-2 model outputs across sizes

When to avoid

• you need outputs from modern LLMs like GPT-4 or Llama
• you want a dataset for training language models rather than analyzing them
• you need production-ready detection tooling rather than research data
