Nucleus is where your team writes and looks after your workspace’s AI prompts. A prompt is the instruction an AI model works from, such as “read this ticket and give it a category and a priority”. In Nucleus you keep every version of a prompt, try a change before anyone relies on it, test versions against sample inputs, and release the version you trust. You can then see how each prompt performs and what it costs. Nucleus holds your workspace’s own prompts. It does not change the built-in prompts behind Studio’s own features. It is also not where you decide which AI models your workspace may use: Tenant Owners and Workspace Admins do that in Studio settings, under AI Models. Nucleus is for the people who build and look after your AI. Tenant Owners and Workspace Admins can do everything in it. Workspace Members work on prompts, datasets and evaluations day to day.

Key ideas

Prompt

An instruction for an AI model, filed under a product and a type.

Version

Each save that changes the prompt, model or settings adds a version, and the versions before it stay in the history.

Environment

dev, staging or production, each holding one version of a prompt at a time.

Dataset

A set of sample inputs to test prompts against.

Evaluation

A run of a prompt against inputs, with the answers scored by any scorers you add.

Scorer

The marking guide an AI judge uses to score an answer.

From draft to production

You write a prompt and save a new version each time you improve it. When a version is ready, you promote it to an environment. Before it moves, Nucleus checks the version’s latest automatic evaluation. A version that passed goes straight through. Otherwise, what happens depends on the prompt’s quality gate: Nucleus lets it through, asks you to say why it should go ahead, or stops it unless a Tenant Owner or Workspace Admin gives a reason.
