What is Neptune?

Neptune is an experiment tracking and model registry platform built for machine learning teams. It was originally developed by Neptune Inc. and recently acquired by OpenAI to strengthen training infrastructure for frontier AI research. The tool solves the problem of managing and analyzing thousands of training runs by providing a centralized system to log metrics, hyperparameters, and artifacts. Core capabilities include real-time experiment monitoring, run comparison, and deep analysis of model behavior across layers. It supports popular ML frameworks like PyTorch, TensorFlow, and JAX, and integrates with orchestration tools such as MLflow and Kubeflow. Neptune is used by data scientists, ML engineers, and research teams who need to track experiments systematically and collaborate on model development. Its workflow fits both individual researchers iterating on models and large teams coordinating complex training pipelines.
