Their main advantage for now is their super clean API. Open source alternative are already on par with GPT-3.5 and 4 capabilities, they just don't have as good a package but that could change rather quickly too.

I'm not sure if this is true. With GPT-4, I can successfully ask questions in Japanese and receive responses in (mostly natural) Japanese. I have also found GPT-4 capable of understanding the semantics of prompts with Japanese and English phrases interleaved.
Out of curiosity, I tried doing the same with local models like Mistral 7B and I could never get the model to emit anything other than English. Maybe it's a difference in training data, but even then, GPT-4 has an allegedly small set of training data for non-European languages.
Is that true? I was running Llamas on my laptop a few days ago, and it was giving measurably worse results than ChatGPT. I think it was the uncensored 13B model, but if you got something that's on par with ChatGPT that I can run on my own hardware I'm pretty interested.
13B models probably cannot directly compare with ChatGPT 4 which maybe +1T parameters or a 5 way MoE of 200B each - or something like that. So you can not likely run a model competitive with ChatGPT locally in the near term.
