 ## Design Overview
 
-The gradients infrastructure will be built on top of the abstract interfaces for op execution which provide a backend agnostic way of tracing and executing ops. We provide APIs for authoring GradientFunctions and registering them into a GradientRegistry for name based lookup. We provide a gradient Tape API that is close to python’s tf.GradientTape and shares most of the implementation with the existing tape.
