This will be an interesting test to see how fast you can bootstrap GPT-4 level performance with unlimited funds and talent that already has deep knowledge of the internals. With the initial adoption of ChatGPT alongside Copilot, OpenAI's data moat of crawled data & RLHF is pretty vast. And that's not leaving the walled garden of OpenAI. You can simulate a lot of this using other off-the-shelf LLMs (see Alpaca) but nothing is a substitute for real world observed usage.
In a related note, has this meaningfully broken through to the mainstream yet? If a ChatGPT competitor comes out tomorrow that is just as good - but under a different brand - how many people will switch because it's Altman backed? I'll be curious to find out.
