There are a few ways you can potentially make money with a model like GPT-3 or GPT-2 (ChatGPT is just the name for the version of GPT-3 fine-tuned for conversational tasks)
1.
Developing and selling language-based
products or services, such as chatbots, virtual assistants, and automated writing
or content generation tools.
2.
Utilize the model for business-related
applications, such as automated customer service or for generating marketing
copy.
3.
Generating quality content and monetizing it
through ads or sponsorships.
4.
Offering consulting services to other
companies that wish to use GPT-3/2 in their own products or services.
Keep in mind that to use GPT-3/2 you need to have API
access, which would need to be subscribed from OpenAI.
