Who pays for custom GPT usage?

I’m very happy with the new releases and upgrades offered by OpenAI since their first developer conference. I have configured a custom GPT model and I can share the link with other users or make it public, however, is the custom GPT tied to my API keys and if the public uses it, do the charges incur on my account?

Does publicly sharing a GPTs incur additional charges?

A GPT operates in someone’s plus account, so any language model inference charges are borne by OpenAI for operating ChatGPT Plus. If the GPT has actions and makes calls to your API plugin, then you get the minimal data and hosting requirement of servicing the API request of the action on your domain. If your API has features powered by AI on demand, then you could be footing the bill yourself for providing AI-enhanced services.

Thank you for your insight into this matter. I’ll continue to develop the custom model with some peace of mind.
