e: Oh - this is a16z, so yeah probably early access - scratch my additional comments
I agree that I don't like early/insider stuff
That said - I believe Llama 2 is architecturally identical to the previous one and given that they are using 13B it is probably just a drag and drop bin replacement and reload your servers.
We all knew Llama 2 was coming so it might be within the capabilities of a hungry startup with no early access.
