nondeterministic
A system that is not guaranteed to return the same output for a given input.
Plain English Explanation
A system that is not guaranteed to return the same output for a given input. LLMs are generally nondeterministic; that is, LLMs typically generate different responses to the same prompt. Nondeterministic systems are generally much harder to test than deterministic systems. See also probabilistic.
How is it used?
Practitioners refer to nondeterministic when building, training, or evaluating machine learning systems. It appears in research papers, product documentation, and technical discussions about AI capabilities and limitations.
