Hi FluffyPants-senpai! AI2U runs on default models, but the itch.io version exclusively supports OpenAI API key integration as an alternative for players preferring their own keys. Players using their own keys are responsible for managing their keys’ usage, payments, etc. and may need to reach out to OpenAI Support directly.
In case your issue is occurring in AI2U despite using a valid OpenAI API key, please email support@alterstaff.io with more info and we’ll look into it!
