@Catvalente "Hallucinate" might not the best choice of words, but LLMs don't error out like traditional programs and apps. LLMs make mistakes, they misremember, they confabulate, they bullshit; which is something we're NOT used to seeing from computers; it may not (necessarily) infer consciousness, but it's something uncomfortably ... familiar.
Computer programs don't make mistakes, they may encounter scenarios not accounted for by their programing. Assuming there's no hardware issue or data corruption, a calculator app will NEVER make an arithmetic error. You can put in a calculation in a million times, and it will always give you the same answer.

@avocado_toast @Catvalente Yes, procedurally generated worlds and levels in video games have been around for a very long time, but they involve a top-down approach where a number of rules are explicitly hard-coded and used with random number generators to produce unique diversity.
AI, however, uses a bottom-up approach, where the "rules" are organically inferred from the dataset it's trained on, while the dataset itself is not stored within the model in any way that came be directly retrieved.
When an LLM "hallucinates" it has a sort of intuitive understanding of what the answer should look like, and fills in the blanks based on the data it's trained on.
