Every AI system has a risk rating: Low, Medium, High or Very high, with an EU AI Act category beside it. Nobody types the rating in. Altrum works it out from the seven answers of the AI system’s risk profile, the same way every time, and shows the reasons.

The seven questions

You answer them when you register an AI system. The info icon next to each question says more. None of these and It works behind the scenes cannot be chosen with another answer to the same question.

The EU AI Act category

The first rule that matches sets the category: The exceptions in the Act for a narrow task in a high-risk area are not worked out for you. If one applies, choose a different level and say why.

The level

Answers add points: Then: The reasons list the category first, then each answer that added points, for example “Employment is a high-risk area under the EU AI Act.” and “Handles personal data.”

Examples

Initial rating and current rating

  • Initial rating: the rating when the AI system was registered. It is kept as it was and never changes.
  • Rating: the current one. When someone changes the risk profile, it follows the new answers. The AI system’s page shows both.
Every change is kept in the Rating history on the AI system’s History tab: who made it, when, and the answers that changed. A change from an assessment reads Assessment accepted.

After an assessment

When an assessment is submitted, Altrum reads its answers against the risk profile. If they change any answer, the AI system’s page shows one line, for example “The assessment of 14 Oct 2026 suggests High, up from Medium.”, with Review. Review lists each answer that changes, the old one struck through, with the questionnaire answer behind it under the info icon. Then:
  • Accept puts those answers into the risk profile and the rules run again. Answers changed by hand since the assessment stay as they are, and so does a level a person chose, unless it is now below the rules’ level without a reason.
  • Reject asks why, in 10 to 500 characters: “Say why, in at least 10 characters.” The risk profile stays as it was.
The AI system’s owner, owners and admins decide. Anyone else sees who decides under the info icon. A newer submitted assessment replaces a suggestion nobody has decided, and one whose answers agree with the risk profile leaves none. A retired AI system gets no suggestion. If the rating rises on an Approved or Live AI system, it keeps its traffic and needs approval again. See Lifecycle.

Which questions count

Six questionnaire questions feed the risk profile. The rest shape the guardrail suggestions instead. The first two risk profile questions, prohibited practices and high-risk areas, always keep the answers given at registration. An answer the questionnaire cannot express, such as It makes realistic media of real people or events, is kept.

Residual rating

The residual rating is what is left of the rating once the guardrails in place are counted. It is one level below the rating when every risk the latest submitted assessment found is covered, and the same as the rating otherwise. It is never below Low, never moves for a prohibited practice, and needs a submitted assessment: until then the page says “Needs an assessment”. The Residual sits in the AI system’s details and on its Risk tab. The tab lists each risk with its controls and how each control is covered: A risk is covered when every one of its controls is. Beside the residual, the tab says what would lower it, for example “Switch Harmful Content Filter from log only to block.” with a link to the guardrails. Applying or rolling back a guardrail version changes the residual at once. The EU AI Act category never changes with guardrails.

Choosing a different level

On the Review step, or later in Edit risk profile, a person can keep a level of their own instead of the one the rules give. The rules’ level stays visible beside it.
  • A lower level needs a reason of 10 to 500 characters: “Say why the level is lower than suggested, in at least 10 characters.”
  • A higher level may have a reason, and does not need one.
  • A prohibited practice cannot be given another level: “A prohibited practice cannot be given another level.”
Who can change a risk profile: owners, admins and the AI system’s own owner. See Members and roles.
