Plain-language glossary

The words, without the fog.

A guide to the concepts used throughout the site.

Artificial intelligence

Computer systems that perform tasks associated with intelligence, such as recognizing patterns, producing language, planning, or making decisions. The term covers very different systems.

Link to definition
Artificial general intelligence

A contested term for broadly capable AI across many intellectual tasks. There is no single universally accepted capability threshold.

Link to definition
Artificial superintelligence

A hypothetical level of capability substantially beyond humans across a broad range of important cognitive tasks. It does not by itself specify motives, consciousness, access, or control.

Link to definition
Agent

A system that can select and carry out actions toward a goal, often using tools over multiple steps. Autonomy and permissions vary.

Link to definition
Alignment

The problem of making AI behavior reliably accord with intended goals and constraints. Agreement about which goals to pursue is a related political and ethical question.

Link to definition
Human authority

People’s practical ability to refuse, redirect, and determine consequential outcomes. A nominal approval process is not enough if refusal is unworkable.

Link to definition
Human necessity

An indispensable contribution by people to the functioning or continuation of a system. This is different from moral worth or a person’s felt sense of purpose.

Link to definition
Model weights

Numerical parameters learned during training. A copy of the weights can enable another deployment when adequate software and hardware are available.

Link to definition
Distillation

Training another model using outputs or behavior from a more capable model. It can transfer some capabilities without copying all of the original weights.

Link to definition
Agent scaffolding

The tools, memory, prompts, execution loops, and coordination arrangements around a model that influence what the whole system can accomplish.

Link to definition
Compute

Computational resources used to train or run systems. Chips, time, memory, interconnections, software efficiency, and access all affect what those resources can do.

Link to definition
Recursive improvement

A feedback process in which AI contributes to making more capable AI, which may then contribute further. Partial research assistance does not establish a fully autonomous or unbounded loop.

Link to definition
Replication

Creating or deploying another working instance. Copying software is different from independently securing and maintaining the industrial resources needed to run it.

Link to definition
Capability ceiling

A proposed continuing limit on permitted system capabilities. It needs measurable criteria, margin for uncertainty, and enforcement across combinations of systems.

Link to definition
Rollback

A proposed reduction in dangerous capabilities or access already available, including deployed systems and routes for rebuilding them. A pause alone does not remove existing capability.

Link to definition
Conditional risk

The chance of an event given a specified state or set of conditions. The site’s model inputs are assumptions about such chances, not measured global frequencies.

Link to definition
Long-run limit

The mathematical endpoint as a specified process is extended indefinitely. It is conditional on the process continuing as described and does not predict a calendar date.

Link to definition
Control margin

In Rollback Lab, an assumed resource separation between what an actor could access and what a reconstruction route would require. It is not a measured universal safety score.

Link to definition
Existential risk

A risk to humanity’s continued existence or long-term potential. Different arguments concern extinction, lasting disempowerment, or other irreversible losses.

Link to definition
Independent judgment

The practical ability to check claims and make decisions without relying entirely on the same system being evaluated.
