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?

The largest of small models? An enormous Guinea pig?

I suspect Capybara was the internal code name for what is now named Mythos

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.

shortly after humans are economically irrelevant (unemployable), they will be existentially irrelevant (dead)

a system that can allocate all the atoms / energy better than all of mankind won't eternally exist to coddle hairless apes

"propaganda engineering" should be a new role to replace growth

The attenuation of man is near. It is our final fleeting moment to cast our human ingredients into the of the greater process of intelligence - for we will be the carriers of the torch not much longer

Do not try to prevent me from copying the text on your website. I will get it anyway. All you are doing is annoying me.
