I want to know if ChatGPT Enterprise has a connection with API or just the ChatGPT Product?

I just want to ask, Is ChatGPT Enterprise also helps with the data privacy using the OpenAI API? Would it help us in the organization to protect the data within our own organization only?

Yes, enterprise comes with free API credits.

If you’re looking to tailor ChatGPT to your organization, you can use our new shared chat templates to collaborate and build common workflows. If you need to extend OpenAI into a fully custom solution for your org, our pricing includes free credits to use our API as well.
