Hey @some-bird-68569, no worries we're glad to have you on the server.
Botpress actually still uses the GPT3.5 Turbo model, the same one that powers chatGPT. If you have personal access to GPT-4, you can use an PAI call from within an execute code card to get results, but you won't benefit from the nice graphic interface that Botpress uses- everything will need to be done in code.
