The version of ChatGPT that is free for public use, v3.5, is a bit of a joke. It was "fed" a very limited amount of information, only 300 billion words or so and that data cuts off sometime in 2021.
Also it's not actually an AI, it's just an in-development computer program and it can't distinguish fact from fiction. So, for example, if most of the data it has been fed calls an extension a visa renewal then how will it know any different?
I don't understand why people are putting so much store by it. Perhaps they're the ones with "artificial" intelligence.
