Language models are built to produce useful responses from patterns learned during training. A fluent sentence can be appropriate, misleading or simply incorrect. The style of an answer does not establish the quality of its evidence.
Experts examine reliability across tasks and situations. A system may be strong at summarization but weak at a particular calculation, source attribution or unfamiliar question.
Useful safeguards include testing against reference material, showing uncertainty, checking citations and making human review part of high-stakes decisions.
A practical reader habit is to ask: What primary source supports this claim? If an answer cannot be checked, confidence should be limited.
This article is a source-linked explainer, not a claim of firsthand interviews or exclusive reporting.
We want errors brought to our attention and corrected openly.
