1. You use their services which makes them money (e.g. you're returned good flight info and book through chatgpt, they get commission)
2. You sell access to end users. The requests can be authenticated so you can give your paying users access to your stuff through an advanced natural language engine for the implementation cost of roughly adding a file explaining your APIs.
plugins dont need to make money, you are still using tokens and paying for those. the more plugins you use, the more conversation you also need and tokens
Yes, I think OpenAI has a business model here (token/subscriptions) but how do the external services make money? Will many of these apps be cannibalized by ChatGPT and other LLMs? For example, the Speak plugin for language teaching, at what point is ChatGPT good enough to do everything that Speak does?
