How good is the new Claude Fable 5 (Mythos) from Anthropic?

Well, it cloned Notion ($10B app) perfectly in 2 prompts. Here's how…

Fable 5 is a different kind of AI model.

It's a step change in the world of AI, and it's also incredibly expensive to run.

But right now, you get usage as part of your Claude subscription.

And not only can it build apps incredibly well, it can pretty much nail them in one shot.

This test I gave it a simple prompt and it:

– Researched Notion and copied it EXACTLY
– Created a plan, architecture, build, everything it needed
– Setup my database and backend on Convex
– Tested and debugged itself

Now I'm the anti-hype guy but honestly, Fable 5 is wild.

If you haven't tried it, go and do it.
