PyRAT is an abstraction-based tool used to verify the safety and robustness of neural networks in critical areas such as healthcare, transportation, and energy. This paper describes the various abstractions PyRAT uses to find reachable states from neural network inputs, as well as the tool's key features for fast and accurate analysis of neural networks. PyRAT has already been used in several collaborations to ensure safety, and its performance was proven by placing second at VNN-Comp 2024.
