Models API

There are three ways to create Keras models:

  • The Sequential model, which is very straightforward (a simple list of layers), but is limited to single-input, single-output stacks of layers (as the name gives away).
  • The Functional API, which is an easy-to-use, fully-featured API that supports arbitrary model architectures. For most people and most use cases, this is what you should be using. This is the Keras "industry strength" model.
  • Model subclassing, where you implement everything from scratch on your own. Use this if you have complex, out-of-the-box research use cases.
