Based on that groups success, they've recently proposed a mini project inspired by GPT that I am considering funding; the data its trained on is all publicly available for free, and most it comes from Common Crawl. I suspect that it will also yield similar results, where you can tailor your own version of GPT and get reasonably good models for a fraction of the price as well. We're no where close to the scale of Big Tech giants, but I've noticed for the better part of 15 years that small companies can actually derive a great deal of the benefits that larger companies have for a fraction of the cost if they play it smart and keep things tight.
