—Overview
What is Keras.js?
Keras.js allows developers to run machine learning models built with Keras directly within web browsers, leveraging WebGL 2 for GPU acceleration. This tool is essential for creating interactive and dynamic web applications that require real-time inference capabilities without server-side processing.
Key differentiator
“Keras.js stands out as a unique solution for running Keras models directly in web browsers, offering real-time inference with GPU acceleration via WebGL 2, which is not commonly available in other similar tools.”
