Model demos anyone can use

Gradio wraps any Python function in a web UI — image upload, text in/out, audio, you name it. It is the default for Hugging Face model cards and papers that need a live demo.

Who it's for: ML researchers and engineers who want a quick, model-facing interface to share with non-technical users.
