Hallucination

BytapaScript

Also known as: Confabulation

In a nutshell

When a model confidently produces wrong or made-up information.

What it means

When an AI produces information that sounds convincing but is incorrect, fabricated or unsupported.

💡 A student confidently giving an answer despite not knowing whether it is correct.

Why it matters

Hallucinations can damage trust and cause business problems; evaluation, grounding and validation can reduce their impact.

Common misconception

Hallucination is not the model lying — it has no notion of truth, only of what text is likely.
