ZeroGPU enables efficient use of Nvidia H200 hardware in Hugging Face Spaces by allowing users to avoid keeping GPUs locked during idle periods. The article discusses how ahead-of-time (AoT) compilation with PyTorch can significantly enhance performance, reducing processing time for generating images and videos with speedups of 1.3x to 1.8x. It also provides a guide on implementing AoT compilation in ZeroGPU Spaces, including advanced techniques like FP8 quantization.
