If you are now understanding, and seeing that you need to offer an AI service yourself if you wish to offer services to others, you will need to start down a path requiring technical competence and programming skills: setting up servers and a backend that can manage a customer database and enterprise user management, user interface for those clients and services, and user interface for a chat assistant.
OpenAI provides an API to get AI responses to input, but does not provide the infrastructure for your own AI business like poe.com or forefront.ai.
A working demonstration app using API and increasing user base will allow you to get higher limits on an OpenAI account, and also and a case for acceptance to Microsoft Azure OpenAI services for high-volume API apps.
If you have none of these skills in your company, nor connections with development partners, it may be hard to start a whole new business in this space.
