RogueGPT Stimulus Corpus: A Multilingual LLM-Generated News Dataset

A multilingual corpus of 2,308 text fragments generated by seven large language models (GPT-3.5 Turbo, GPT-4o, Gemma 7B, Llama 2 13B, Mistral 7B, Phi-3 Mini, GPT-4) and sourced from human journalists, designed for research on AI-generated disinformation detection. The corpus follows a four-quadrant design crossing content origin (Human vs. Machine) with veracity (Real vs. Fake) across four languages (English, German, French, Spanish) and three formats (tweet, headline, short article). Created using the RogueGPT platform as part of a doctoral dissertation on the AI-driven disinformation ecosystem at Frankfurt University of Applied Sciences.
