imgsys is a crowdsourced image generation arena that lets users compare outputs from different AI models side-by-side. Built by fal.ai, it ranks open-source text-to-image models based on real user preferences using an Elo-style rating system, similar to how LMSYS Chatbot Arena benchmarks LLMs.
Users compare two images generated from the same prompt without knowing which model produced each one, ensuring unbiased evaluation
Models are ranked using an Elo rating system derived from thousands of user preference votes, providing statistically meaningful leaderboards
All voting results and preference data are published as open datasets on Hugging Face for community research and analysis
Specializes in benchmarking open-source and open-weight image generation models like FLUX, Stable Diffusion XL, and others
Users can enter any text prompt and immediately see how different models interpret and render it
Live-updated rankings reflecting the latest community votes and model performance trends
Developers building AI image applications can use imgsys rankings to choose the best open-source model for their project
Researchers can leverage the public preference data to study human evaluation of generative image quality
AI enthusiasts can contribute votes to help the community identify the best-performing image generation models
