This was sold to me as a small pup (thin -> thick section is when I started taking care of it) with the explicit information that it's a San Pedro.
I've ran pictures of it through ChatGPT knowing it's been trained on tons of cactus data, but it keeps telling me it's a "Fairy Castle" cactus (Acanthocereus Tetragonus) with a close look-alike being a young Cereus (Peruvian Apple cactus).
I'm still learning and growing, but I'd like the community's feedback on what it is I most likely have. Thank you! ❤️

lol
Sounds like chatGPT is telling YOU a fairytale ! The person that sold you this informed you correctly and it is in fact a San Pedro Cactus .

GPT think my bridgesii is a toothpick cactus lol
Told me at one point Bruce’s Dragon was Myrtillocactus geometrizans cv. Bruce’s Dragon.
LMM are useful only if you have some kind of knowledge on the topic as you can guide che AI into the correct answer, otherwise it is useless. This is indeed a tricho
Chat gpt doesn’t even know that cactuses (or you) are a thing that exists, per se.
It shouldn’t be trusted like some kind of expert.
confusion can be avoided by not using chatgpt. you got a trichocereus
Yes, ChatGPT is wrong, but I can clearly tell why it would get this mixed up, Acanthocereus can appear round and then flare out in the same manner once it starts getting what it needs
