We're releasing Claude Fable & Mythos 5.2! They're good models, I have some demos and tips for you.

Fable beats Opus on big, long tasks. Good examples are rewriting an entire codebase, creating an excellent first draft of a large artifact, or exploring ambiguous scenarios.

I expect to see it used to port a lot of stuff to Rust, support journalists in large-scale investigations, and help with research & science. I often still prefer Opus 5.5 for everyday work. Fable's got a big brain and thinks a little slower.

I've asked it to make some games, keeping the very first draft. I'm most impressed with Claude's first-person shooter! Try them here:

I also asked it to create 20 different logos for a made-up group called "Interchange".

Mythos is once again a step up in cybersecurity. If you're a defender and hardening your own work, a reminder that it's much easier to get access to Mythos now, even for indivudals: support.claude.com/en/articles/14…
