The concept of factuality doesn't exist in the model at all. I'm not super familiar with ChatGPT internals, but there are plenty of ways to tack on uncertainty estimates to predictions of typical "large scale ML models" without touching Bayesian stuff (which only work for small scale academics problems). You can do simple parametric posteriors estimation or if all you have is infinite compute and don't even want to bother with anything "mathy", bootstrapping is the "scalable / easy" solution.
