I haven't looked it up. If it's the same as before there aren't that many restrictions. You can't use it commercially if you have like more than 700 million users. So basically if you're Google, Amazon or OpenAI. Everyone else is allowed to use it commercially. They have some stupid rules how you have to call your derivatives. And they're not liable. You can read the license if you're interested.

What people would use? They'd use exactly this. Probably one of the smaller variants. This is state of the art. Or you'd use some of the competing models from a few weeks or months back. Mistral, ... You'd certainly not train anything from ground up. Because it costs millions of dollars in electricity and hardware (or cost for renting hardware).
