Mythos is a news article. This is an actual model you can use.

That's a really good question, my sarcastic mind thinks that Anthropic rushed the Mythos announcement of fears of Meta stealing their thunder... (I guess someone leaked that, a LOT of anthropic folks are ex meta... so, you know)

Just a speculation, I have no real knowledge about it.

I think Anthropic did the mythos announcement to undercut OpenAI’s upcoming next model announcement, not Meta’s.

Why not? Not everything has to be SOTA to be interesting.
