Using Neptune

How do I find my API token?

In the bottom-left corner of the Neptune app, open the user menu and select Get your API token.

How to find your Neptune API token

You can copy your token from the dialog that opens. It's very long – make sure to copy and paste it in full!

How do I find my project name?

Your full project name has the form workspace-name/project-name.

For example, if your workspace name (shown in the top-left corner) is "ml-team" and your project is named "classification", your project string is: "ml-team/classification".

  • To copy the name to your clipboard, navigate to the project details ( Details & privacy).
  • You can also find a pre-filled project string in Experiments Create a new run.
Can I change the location of the .neptune directory?

Yes. Normally Neptune creates the .neptune data directory in the CWD. You can:

What's the difference between runs and the model registry?

Can I generate and detect data drift with Neptune?

Not directly, as Neptune focuses on experiment tracking. You can, however, use external tools to simulate and detect drifted data, such as TorchDrift and Captum . Afterwards, you can log the result (image with drift distribution for a specific experiment) to Neptune.

Check out an example of logging production data drift with Evidently, or see Essential logging methods for general tips.

Can I deploy Neptune on my own infrastructure?

Yes! See Self-hosted Neptune.

Can I keep my sensitive data private while working with Neptune?

You can fully control what metadata is logged and sent to Neptune. You can also choose to only track the metadata and version of files instead of uploading their contents to Neptune.

How do I suppress the console output when interacting with runs?

See Set the logging level.


What are the storage limits?

Included storage quotas are listed on the pricing page on the website. You can always add extra storage to your subscription.

Workspade admins can also set project specific limits, which may differ from the total limit of the workspace.

What's the maximum number of runs?

There are no limits. As long as there's storage space, you can have as many runs as you wish.

How many users can I invite to my workspace?

You can invite as many users as you've purchased seats for. Note that the Free and Team plans have limited seats per workspace.

For details, see the pricing page on the website.


How many projects can I have?

On the paid plans, there are no limits.

On the Free plan, you're limited to one project at a time.

What is an archived project?

An archived project is hidden and in read-only mode, so you can't modify it or add metadata to it. All of the metadata contained within the project remains intact and can be accessed via the Neptune API.

If you unarchive the project, you can use it normally again. Learn more about Archiving projects →

Can I unarchive a project?

Yes, you can unarchive a previously archived project. However, if your quota is full, you need to upgrade your subscription or archive other projects first.
