Capability versus reliability
A capability is something a system can do in at least one case (what a demo shows); reliability is how often it does it correctly across inputs you did not choose (what an eval measures). Trust depends on reliability, and mistaking a demonstrated capability for reliability is the central error of the module.
Defined in 2 GAGE programs, which carry 3 distinct definitions of it. The wording above is taught in Certified AI Governance Professional (CAIGP).
How each discipline defines it
The same term does different work depending on who is using it. These are the definitions as each program teaches them, unedited.
A capability is something a system can do in at least one case (what a demo shows); reliability is how often it does it correctly across inputs you did not choose (what an eval measures). Trust depends on reliability, and mistaking a demonstrated capability for reliability is the central error of the module.
The distinction between what an agent can attempt (almost anything phrased as a goal) and what it can reliably do on the real, messy version of a task (a separate, usually lower, empirically-measured number). Delegation depends on the reliability, not the attempt.
The core distinction of this topic. Capability is what an agent can do in its best moment (often shown in a demo); reliability is how consistently it does the task correctly, unsupervised, across varied real conditions. The gap between them is large in 2026.

Where it shows up at work
A definition is where Capability versus reliability starts. The lessons above teach it inside the competencies below, which are what job descriptions ask for and what the GAGE credential records. Every link here is drawn from the same careers map that builds a role's readiness check.
Defines who reviews AI outputs, what they check, when they can override, and how to keep review from becoming a rubber stamp.

Knows when to trust, verify, escalate or override an AI recommendation, and stays accountable for the decision.

How job descriptions say it
Postings rarely use the textbook word. These are the phrases the careers map reads as asking for the competencies above.
Where the frameworks place it: EU AI Act Article 14; ISO/IEC 42001 Annex A; NIST AI RMF GOVERN.
One interview question about it
Design the human oversight for an AI system that approves refunds. What does the reviewer see, and what stops rubber-stamping?
Asked of candidates for human oversight design. Answering it in your own words is exactly how a GAGE topic is passed, and the credential records the pass where an employer can check it.
If you come from another field
Some backgrounds already carry this competency, and the readiness check gives credit for it.
- Operations, claims, customer service and administration carries it as a claim to back up: Deciding when to escalate a case is judgment under uncertainty.
- A computer science or software engineering degree carries it as work you can show: Prompting and tool workflows are already in your daily work.
