I have a professional account with access to the 0-1 professional model. Please forgive me if I use simplified terms. When I create a custom GPT, I’m unsure which underlying model is being used because there is no information available. I’m interested in knowing if it’s possible to create a custom chat GPT with the 0-1 professional model as the underlying model.
Hi @principal5

Custom GPTs use GPT-4o. We cannot build custom GPTs on o1 model.
