It does have the ability, you haven't allowed it to. If you're completing the sentence "What is the current price of Apple?..." based on the internet as a training source, the most likely reply is not: "Well, let's think about how we'd go about this, I should do a search for AAPL, and then..." The most likely completion is: "The price of AAPL is $X" OpenAI had to "artificially" bias it to say "I can't answer that" or it'd happily tell you a million things like that. — On the other hand, give the LLM room to plan, it will plan. If you ask it "To answer x what do you need", it does better at answering x The most likely completion to "How would you tell me Apple's current price", is a logical step by step process. And that's how it gets a chance to check itself. I think people underestimate how much logic the model can do in a single pass, LLMs need to output things that we assume can be done with working memory
