If you look closely at the screenshots, it comes with a Movidius Chip on the VisionBonnet board. I'm guessing this VisionBonnet accessory is simply another spin on the Intel "Movidius Neural Compute Stick" with the Movidius Chip wired directly to the CSI Camera port and the GPIOs on the Zero used to talk with it. So you probably develop on it using the same Movidius Toolchain you use for the Neural Stick: http://developer.movidius.com http://developer.movidius.com Their SDK recently had a major release with TensorFlow support included, which I bet drives this. (Even with Tensorflow Lite optimizations, the RPi zero is probably just too weak to drive inferences for any non-toy model.)
