Google has a speedy new AI chip it doesn't really want to talk about

Google yesterday confirmed rumors that it has been working on a custom chip designed to speed up computing related to its artificial intelligence efforts. The result, it said at its I/O developer conference, is a chip it calls a Tensor Processing Unit. It's designed to work with TensorFlow, an open source software library for developing AI applications. The TPU chips, Google says, are designed to be built into its existing computing infrastructure and are already in use boosting the performance of services like Street View and voice recognition. They also played a part in Google's AlphaGo software that defeated the human champion at the board game Go.
