What is Keras?
Keras is a deep learning API written in Python that runs on top of JAX, TensorFlow, or PyTorch. It focuses on debugging speed, concise code, maintainability, and ease of deployment. You can build and train models for computer vision, natural language processing, audio, time series forecasting, and recommendation systems. KerasHub provides popular model architectures and pretrained checkpoints from Kaggle Models, and it supports scaled training from laptops to large GPU and TPU clusters.
- JAX, TensorFlow, and PyTorch multi-backend (OpenVINO is inference-only)
- 20–350% speedup by choosing the fastest backend for your model
- KerasHub pretrained models (Kaggle Models checkpoints)
- KerasTuner hyperparameter tuning
- Building models and layers with the Functional API and subclassing
- Built-in training and evaluation with model.fit
- Scaling training up to GPU and TPU clusters
Who uses Keras and for what
- Developing computer vision, natural language processing, audio, time series, and recommendation models
- Deep learning in research institutions and production services (CERN, NASA, and Waymo use cases)
