What is a large language model?

An AI model trained on vast amounts of text to predict likely next words. It powers ChatGPT, Claude, Gemini, and most Christian chat apps.

Why it matters for Christians

It predicts plausible language. Plausible is not the same as true.

What to do

Expect fluent answers, and check the facts. Ask for chapter and verse, then read them. Do not take a confident tone as proof.
