Model Card
Definition
A short structured document describing an AI model's intended use, training data, performance, limitations, and ethical considerations.In-Depth Explanation
Proposed by Mitchell et al. in 2019, model cards standardize transparency for machine-learning models — sitting somewhere between a README and an academic paper. They typically cover intended and out-of-scope uses, training and evaluation data, metrics across groups, and known risks. Hugging Face popularized them as the README on each model repository, and the EU AI Act's GPAI rules push toward similar disclosures. A good model card helps users avoid misapplying a model.
Real-World Example
