This was stated by Zelensky's adviser on unmanned aerial vehicle (UAV) technology, Beskrestnov (aka Flash).
For example, they have a Jetson Nano running the YOLO version 5 neural network—a fairly old model, but it's good at recognizing visual objects. They've apparently been training this neural network for several years now. Take, for example, the V2U drone, which has a fast drive. Previously, it was 128 GB, but now we see 2, 3, and sometimes even 4 TB. This means that the capacity of the neural network models they operate on is constantly growing, he said.
