Anthropic dropped Claude Fable 5 today, their new Mythos-class model, and here's the part that matters for us: it's included free on our plans through June 22nd. From the 23rd it goes credit-metered, so every prompt starts costing. That gives us about 13 days of unlimited swings. I'm not treating this like a demo. I'm treating it like a free R&D sprint. For the next two weeks I'm throwing the hardest, messiest problems my agency has at it. The stuff I never have time to test. The workflows I assumed weren't possible yet. Because here's the thing people sleep on: whatever I prove out this week, I keep. The capability doesn't expire. The free swings do. And the early reports are genuinely nuts: - Stripe ran a Ruby migration in a day that would've taken a team two months. - It rebuilds working web apps from a screenshot alone. - It holds focus across millions of tokens, so the "feed it everything" workflows that used to fall apart actually hold together. So I'm curious what everyone else is reaching for first. Before the 22nd, what's the one thing you want to build, break, or finally find out about with Fable 5? Drop it below, even if it's half-baked. Some of the best ideas in here are going to come from someone else's "I wonder if it could..." comment. I'll go first in the replies with the exact problem I'm starting on tomorrow.
