NVIDIA Model Optimizer
NVIDIANVIDIA Model Optimizer is a library of model-optimization techniques - quantization, pruning, neural architecture search, distillation, sparsity and speculative decoding - composed through Python APIs. It takes Hugging Face, PyTorch or ONNX models and exports optimized checkpoints for downstream deployment stacks including TensorRT-LLM, TensorRT and vLLM.
