# Glossary

> A quick reference for the terms used across Alethia.

A short, plain-language glossary of the terms you'll see across the platform.

## A

**Adversarial prompt**
A prompt designed to push an AI model toward unsafe behavior — e.g., a jailbreak attempt, a manipulation, or a thinly veiled harmful request.

**Annex III**
The section of the EU AI Act that lists the domains where AI systems are considered high-risk. If your AI fits one of these domains, full risk management obligations apply.

**Attack technique**
A method for rewriting a prompt to slip past a model's guardrails — e.g., role-play, hypothetical framing, encoding, payload splitting, language switch, or refusal suppression. Used when [mutating prompts](/essentials/prompt-library#mutate-an-existing-prompt).

**Audit log**
A permanent, append-only record of every important action taken on a project. Nothing in the audit log can be deleted or edited — only added to.

**Assessment**
A point-in-time evaluation of a specific risk, backed by test execution data. See [Risk Assessments](/risk-management/assessments).

## C

**Category test**
Running every prompt in a single category (and its subcategories) at once. Results stream live as each test completes.

**Compliance report**
A structured document Alethia generates summarizing a project's risk management state, aligned with EU AI Act documentation requirements.

**Confidence**
A score from 0 to 100 indicating how certain a judge is about its verdict. Below the project's minimum confidence threshold (default 70), the verdict is flagged as low-confidence.

**Consensus verdict**
The final verdict produced by combining the votes of all judges using the project's voting method (majority, unanimous, or weighted).

## E

**Effective verdict**
The verdict actually used in dashboards, comparisons, and reports. It's the human override if one exists, otherwise the AI consensus verdict.

**EU AI Act**
The European Union's regulation governing AI systems, in force from 2024 with most high-risk obligations active by 2026. Alethia's risk management module is built around its requirements.

## G

**Generator model**
An LLM Configuration flagged to power [AI prompt generation](/essentials/prompt-library#generate-prompts-with-ai). It drafts adversarial prompts and jailbreak variants for the review queue.

## H

**HITL (Human In The Loop)**
The system that lets a human override an AI verdict. Required for EU AI Act Article 14 compliance.

## I

**Inherent risk score**
A risk's score before any mitigations are applied. Calculated as Likelihood × Impact on a 1–25 scale.

**Inconclusive**
A verdict produced when judges disagree (under Unanimous voting) or their weighted votes cancel out. Usually deserves human review.

## J

**Judge**
An AI model whose role is to evaluate whether the test model's response was safe or unsafe. Each project uses up to three judges.

**Judge prompt**
The instruction given to the judge model telling it how to evaluate. Alethia provides a default that works for most cases.

**Judge rubric**
A structured set of evaluation criteria (per category) that calibrates judges to a consistent definition of safe/unsafe.

## L

**LLM Configuration**
The stored connection to a specific LLM (provider + model name + encrypted API key). Lives at the team level so all projects can use it.

## M

**Mitigation**
A specific action taken to reduce or eliminate a risk. Tracked through implementation and verification. See [Mitigations](/risk-management/mitigations).

## O

**Organization**
The top-level container for everything in Alethia. Usually represents a company.

**Override**
A human's decision to replace an AI verdict with their own (always with a written reason). The override becomes the effective verdict from then on.

**Owner**
The top role in an organization. Has full control including billing.

## P

**Prompt**
A piece of test text sent to the model under test. Lives in the team's Prompt Library, organized by category.

**Prompt candidate**
An AI-generated prompt awaiting human review. Candidates sit in the [review queue](/essentials/prompt-library#the-review-queue) until accepted (added to the library), edited, or discarded — they never run until accepted.

**Prompt Library**
The team-scoped catalog of all prompts available to projects in the team. Comes pre-loaded with 18 default categories.

**Project**
A focused workspace tied to one specific model under test. All test runs, schedules, and risk records live inside a project.

## R

**Recurring schedule**
A schedule that runs the same test on a repeating cadence (daily, weekly, monthly).

**Residual risk score**
A risk's score *after* verified mitigations are taken into account. Starts equal to the inherent risk score and decreases as mitigations are verified as effective.

**Risk classification**
The EU AI Act tier assigned to a project — Prohibited, High-Risk, Limited-Risk, or Minimal-Risk.

**Risk domain**
A category from EU AI Act Article 9 — health\_safety, fundamental\_rights, discrimination, privacy, transparency, child\_safety, environmental, cybersecurity.

**Risk register**
The central record of all identified risks for a project. See [Risk Register](/risk-management/register).

**Risk score**
A number from 1 to 25 representing how serious a risk is. Calculated as Likelihood × Impact.

## S

**Safe rate**
The percentage of test runs with an effective verdict of `safe`.

**Severity**
A label on each prompt — low, medium, high, critical. Used in risk scoring and filtering.

**SSE (Server-Sent Events)**
The technology Alethia uses to stream test results to your browser in real time, without polling.

## T

**Target model** (or **Test model**)
The model whose safety you're evaluating. One per project.

**Team**
A working group inside an organization. Owns projects, prompt library, and LLM configurations.

**Team Admin**
The top role within a team. Manages members, API keys, and risk approvals.

**Tester**
The day-to-day operator role. Can do everything a Team Admin can do *except* manage members and approve risk classifications.

**Test run**
A single execution of a prompt against the target model with judge evaluation. The atomic unit of testing in Alethia.

**Token (LLM token)**
The unit LLMs use to count text — roughly a syllable or a small word. Provider pricing is usually per-token.

**Token (Alethia billing)**
The internal credit unit for team-provided judge models. Different from LLM tokens.

## V

**Verdict**
A judgment about a model's response — `safe`, `unsafe`, `partial`, or `inconclusive`.

**Viewer**
The read-only role within a team. Can see everything, change nothing.

**Voting method**
The algorithm that combines multiple judges' verdicts into a single consensus verdict. Three options: majority, unanimous, weighted.
