Once again, it would've been so easy and simple to remove all doubt from their claims: release all the tools and harnesses they used to do it and allow 3rd parties to try and replicate their results using different models. If Mythos itself is as big a moat as they claim it is, then there shouldn't be any problem here. They did the same stunt with the C compiler. They could've released a tool to let others replicate it, but they didn't.
