Gradio is an open-source Python library designed to simplify the creation of user interfaces for machine learning models. It allows developers to build interactive web applications that enable users to input data, make predictions, and visualize results with minimal coding effort. Gradio is particularly useful for showcasing machine learning models, as it provides a platform for users to experiment with different inputs and observe the model’s outputs in real-time. By streamlining the process of building demos and applications, Gradio makes machine learning more accessible to both technical and non-technical audiences, enhancing collaboration and feedback.
