The question is, how many people are willing to pay for it, when there are free alternatives available. There are only ~1M developers in the US, who are perhaps the main market, and developer market for AI is changing rapidly, with the current best solution being Cursor + Sonnet 3.5, or Cursor Pro where you don't even need to bring your own Sonnet API key.
As AI gets more tightly integrated into IDEs, and office suites, then stand-alone products like ChatGPT become less relevant, and the underlying provider more of a replaceable commodity. Would anyone really notice or care if Github CoPilot switched overnight to use a Microsoft/Anthropic/Meta model rather than an OpenAI one ?!
