Rumor is that Claude Mythos will release to the public today. It's possible that it will be named Claude Fable 5, but I'm not going to be a stickler for the name and will resolve this yes as long as Anthropic says it's Mythos or a Mythos-class model.

Being released to the public means that a normal American can access it in exchange for money. I assume that I will have access if so.
