On graph, they are still slightly bellow Mythos. Maybe enough to not be prohibited by US government?
My guess is that it's same base model as 5.5, but with additional post-training to improve and benchmaxx on a few things like that.
If they really thought it was competitive with Mythos/Fable across the board, then why wouldn't they release a broader set of benchmarks, and why price it day 1 at 1/2 the cost of Fable?
