Model ID Convention

Every model has an ID: the model value on the API, the argument to /nito:model or --model in the Plugin, and the name under each row of the Browser App picker.

The Shape

<maker>/<model>

anthropic/claude-sonnet-5
openai/gpt-5.5
moonshotai/kimi-k3

You hold no accounts with the makers. The ID is the catalog name Nito uses so one account reaches them all.

The `:confidential` and `:encrypted` Markers

A model that offers a stronger level gets a separate entry, with the level on the end of the name:

z-ai/glm-5.2                 # the Private entry
z-ai/glm-5.2:confidential    # the Confidential entry
z-ai/glm-5.2:encrypted       # the Encrypted entry

These are separate catalog entries. You never add the marker yourself; you pick the entry. The Model List shows which models carry them. The :encrypted entry is available in the Browser App today and on the API with the Encrypted headers. In the Plugin, choosing one returns a message pointing you to Anonymous, Private, or Confidential. See Encrypted.

Level in the Name

The plain entry, the :confidential entry, and the :encrypted entry are different models at different levels. The level cannot drift, and it never silently downgrades: a call the model cannot serve at its level fails with a clear message. See Privacy Levels.

Logical Names

The ID is a stable public name. Nito maps x-ai/grok-4.6 to whichever backend serves it, and the name stays the same as the plumbing changes.

In Practice

Confirm IDs from the picker, /nito:models, or GET /v1/models; the catalog changes over time.
A :confidential marker means Confidential. No marker means the model’s own level, Anonymous or Private.
