>ChatGPT cannot uncover anything, especially the municipality-specific corpus of codes that the comment ostensibly claims to have access to.
It's possible the training set includes those codes (or a citation of those codes). It's possible that they used GPT4 with Browsing, or that it gave them the right terminology to search for & they then pasted in sections of the code and asked it to work off that.
It's also entirely possible ChatGPT hallucinated these utility code sections to support its case and the people working for the utility didn't call their bluff... which is essentially exactly what this story is about, except they got caught out because ChatGPT's bluff was called...
