So,

Um, it's basically, this is what happened.

There was a configuration error on, on Theropics content management system, basically their blog backend.

And that made a bunch of unpublished draft posts publicly accessible.

So, you know, when, when a company is getting ready to have a big announcement and they want the blog posts published ahead of time and it kind of set up and ready to go, ready to post wherever they want it.

And they had about 3000 assets that were never meant to be live.

All of those were buried in the documents.

Um,

And there was one of them that was a draft blog post about a model called Claude Mythos.

So Anthropic has since confirmed that the model is real.

A spokesperson said that it represents, quote, a step change in AI performance.

And it is, quote, the most capable model we've built to date.

So this isn't speculation.

Anthropic has actually acknowledged that this exists.

I think what makes this really interesting is that this was in those documents.

The leak references a new model tier called Capybara.

So basically for context right now, Anthropic has Haiku, Sonnet, Opus, and those are kind of like their three from lowest to highest.

Opus is their best model.

Sonnet is kind of their medium and Haiku is their light model.

Capybara is above Opus.
