What type of API interface does Keras provide?

Keras provides advanced API interfaces, including the Sequential model API and the functional API. The Sequential model API is a simple way to build models, suitable for linear stack models. The functional API, on the other hand, is more flexible and can be used to construct complex neural network structures, including models with multiple inputs and outputs. Keras also offers low-level API interfaces, such as layers and loss functions, for customizing models and loss functions.
