Neptune
Track experiments, monitor training, and understand complex model behavior

Neptune is an experiment tracking and model monitoring platform designed for AI researchers and developers. It helps teams track training runs, compare experiments, analyze metrics across layers, and surface issues during model development. Neptune has been acquired by OpenAI to be integrated into their frontier model training infrastructure.
Neptune provides a platform for tracking experiments, monitoring training runs in real time, and comparing thousands of runs with detailed metric analysis.
