The worry, that is borne out by the pricing of Uber, isn't that LLMs are more expensive than the generation before, but that it's a VC play. Get into market, undercut your competitors until they go bust, then raiser prices. Ubers used to be $1, which was obviously totally unsustainable. Now Uber's only competing platform is Lyft, and Uber is making money as of their latest quarter. Ubers are not at least $10 if not $50 $100. ChatGPT's $20/month looks like $1 Ubers to some. Only insiders know how much it actually costs OpenAI to support ChatGPT users. I will note, however, that GitHub free private repos are supported by corporations paying for their own private GitHub, so it's unclear that ChatGPT's $20/month ever has to be raised with enough $200 or $2,000 or $20,000/month users.
