Neptune.ai
Definition
Neptune.ai was a platform for documenting ML experiments.
The service recorded training runs, metrics, and artifacts. It was permanently discontinued in March 2026 and is therefore not a current recommendation for new projects.
Simply explained
The former digital lab notebook can no longer be planned as an ongoing service today.
Why it matters in practice
Historical documentation and existing references must be read in the correct temporal context.
Example from business
Hypothetical example: A team replaces an old Neptune reference in its internal documentation with an available tool.
Limits and pitfalls
- Old tutorials may still appear accessible even though the API and interface have been shut down.
Origin & history
Neptune developed experiment tracking; after acquisition by OpenAI, the service was discontinued.
Use in mid-sized companies
- SMEs should recognize old dependencies and incorporate received exports into a maintained process.
Frequently asked questions
Can new Neptune experiments be created today?
