  Adan is a cutting-edge Adaptive Nesterov Momentum optimizer specifically engineered for significantly faster and more efficient training of deep learning models. It delivers superior performance and faster convergence, particularly benefiting large language models (LLMs) and diffusion models, outperforming many traditional optimizers. This repository provides the official PyTorch implementation.

  ## Key Advantages of Adan
  
  - **Faster Convergence:** Achieves optimal performance in fewer training steps compared to conventional optimizers.
  - **Improved Generalization:** Leads to models with better performance on unseen data.
  - **Optimized for Large Models:** Particularly effective for training large language models (LLMs), vision transformers (ViTs), and diffusion models.
  - **Adaptive Nesterov Momentum:** Combines the benefits of adaptive learning rates with Nesterov momentum for robust and efficient optimization.
