Keras

Keras is a framework maintained by Keras team at Google6 3. Its source code is public1 3 under the Apache License 2.02.

Keras is an open-source deep learning API. Keras 3 is multi-backend: models can run on JAX, TensorFlow, or PyTorch, and an OpenVINO backend supports inference only. The keras.io site also documents KerasHub, which provides Keras 3 implementations of model architectures paired with pretrained checkpoints.1 4
