Anthropic is preparing to release new models – Mythos and Capybara

Surely this was a draft blog post that was leaked right? Placeholder images. The tone of the article is not as professional. Feels like it needs more meat on the bones. Regardless, it seems like this is maybe something like GPT 5.4 Pro or Gemini Deep Think? It could be Opus 4.7 + an agent that spawns multiple versions, spends a ton of tokens on thinking and verification, and then give you an answer.

Haiku, Sonnet, Opus, Mythos all make sense… Capybara?

This pattern of AI companies describing their own products as so spectacularly effective that they're dangerous really is a remarkable piece of propaganda engineering. What is happening here would be easily understood and obvious by everybody if it the head of marketing for a food company was on TV talking about how pretty soon everybody will be eating their food, and how it's so unbelievably tasty that it might cause people to leave their families and abandon all other hobbies in pursuit of their delicious product, utterly destroying society as we know it. I mean maybe it'll happen eventually. Maybe we'll all end up with a wire stuck in the back of our heads, floating in a vat of nutritious goo. But what we've seen so far has been an excellent, highly useful, and certainly groundbreaking industrial automation product. Maybe they could just write a blog post telling us what the thing does and how much it costs and when we can try it.
