Neptune 2.x

Neptune is joining OpenAI

Neptune has entered into a definitive agreement to be acquired by OpenAI, subject to closing conditions.

We will wind down the hosted (SaaS) service after a 3‑month transition period ending on March 4th, 2026. Self-hosted customers have been contacted by their account manager to work on a smooth transition path.

For information and instructions, visit the Transition Hub on the main documentation site.

Neptune is an experiment tracker. It enables researchers to monitor their model training, visualize and compare model metadata, and collaborate on AI/ML projects within a team.
