Hey hunters 👋 Hunting this because today Anthropic released the most capable AI model anyone can actually use — and made it free for two weeks. Quick backstory: in April, Anthropic built a model so strong (Claude Mythos) it only released it to vetted cyberdefenders and the US government through Project Glasswing. Fable 5 is that same Mythos-class model, with safeguards added so the rest of us can have it. Same weights — sensitive cyber/bio queries just fall back to Opus 4.8, which happens in less than 5% of sessions. What early testers are reporting: ⚡ Stripe: a codebase-wide migration across 50 million lines of Ruby done in ONE day — estimated at 2+ months for a full engineering team by hand. 🏆 Benchmarks: #1 on Cognition's FrontierCode, #1 on CursorBench ("state of the art" — Cursor's CEO), first model to break 90% on Hex's analytics benchmark, top score on Hebbia's Finance Benchmark. 👁️ Vision: rebuilt a web app's source code from screenshots alone. Beat Pokémon FireRed with raw screenshots — no maps, no helper harness. Previous Claude models needed heavy scaffolding to even play. 🧬 Science: Anthropic's protein design experts report ~10x acceleration on drug design steps. One of the model's novel biology hypotheses was independently corroborated by an outside lab. 🎮 The announcement page has live demos worth seeing — a solar system simulator derived from physics first principles, autonomous Factorio play, and a CAD editor the model built including its own AI copilot: https://www.anthropic.com/news/c... 💰 Pricing & access: • API: $10/$50 per million tokens (less than half of Mythos Preview) as claude-fable-5 • Subscriptions: included FREE on Pro, Max, Team & Enterprise plans through June 22 • After June 23 it requires usage credits until capacity expands One wrinkle worth knowing: Mythos-class traffic carries mandatory 30-day data retention for safety monitoring — not used for training (details: https://support.claude.com/en/ar...). If you've got a Claude subscription, you have until June 22 to try the strongest model on the market for free. So: what's the first thing you're throwing at it? 👇
