Llama proved that GPT-3-3.5 level performance can be squeezed out of relatively wimpy consumer hardware. But GPT-4 is much bigger than GPT-3, so it seems like even optimizing it by orders of magnitude might not be enough to achieve similar results. Is it plausible to expect GPT-4 level performance from consumer hardware in the near future?

The human brain proves there's a hell of a way to go.

Yup

Maybe 7b model can get GPT-4 level performance if trained for _very_ long. Facebook paper showed that performance increased until the end of training and it looks like there was no plateau. Maybe it's just very inefficient but possible? Or maybe there is another way.

Why does performance increase with training instead of parameters?

Check LLama paper: https://arxiv.org/pdf/2302.13971.pdf

Specifically this graph: https://paste.pics/6f817f0aa71065e155027d313d70f18c

They increase performance (reduce loss) with parameters or training time. More parameters just allow for faster and deeper initial drop in error/loss but later part looks the same for all model sizes. At least that is my interpretation.

let's find out. train a small model and fine-tune it on gpt-3 / 3.5 / 4
