No, I tested the paid GPT-4 last year on similar questions (animal cognition) and it was so bad I decided it was a waste of money. I actually don't care if it's maybe gotten better in the past year, and I'm certainly not spending money to find out. Last I checked the best LLMs still have a 5-15% confabulation rate on simple document summarization. In 2023 GPT-4 had a ~75% confabulation rate on animal cognition questions, but even 5% is not reliable enough for me to want to use it.
The high school AI tutor probably wasn't using GPT-4, but the district definitely paid a lot of money for the software.
I also hate this entire argument, that AI confabulations don't matter for free products. Unreliable software like GPT-4o shouldn't be widely released to the public as a cool new tech product, and certainly not handed out for free.
