# {{ product_cloud_tpu }} generations

Tensor Processing Units \(TPUs\) are accelerators for machine learning. This set documents four generations, which share most concepts and tasks but differ in their values.

Each generation has an introduction, a specifications topic, a configurations topic and a VM types topic. Values such as chips per pod are stored once as keys, so a corrected value changes every page that shows it.
