TensorFlow is an open-source library for Machine Intelligence. It is a very flexible library. You can use it for both research and production. You can build intelligent apps, games, and services. It can be run on a CPU or a GPU. The developers can focus on building and training one model to perform well on different kind of data. Some frameworks like Torch and Theano use TensorFlow as its backend. TensorFlow has a shorter learning curve and is easy to use. It has a lot of high-level APIs, so developers can build complex applications using simple programming commands.
