 # Inferences
 
 [TensorRT](https://developer.nvidia.com/tensorrt) is a highly optimized AI inference runtime for NVIDIA GPUs. It uses benchmarking to find the optimal kernel to use for your specific GPU, and there is an extra step to build an engine on the machine you are going to run the AI on. However, the resulting performance is also typically _much much_ better than any PyTorch or NCNN implementation.
