Claude Fable 5: a Mythos-class1 model
Launched this week
Claude Fable 5 is Anthropic's first Mythos-class model available to the public. Instead of refusing risky queries, it routes them to Opus 4.8 through safety classifiers, triggering in less than 5% of sessions. Stripe used it to migrate 50M lines of Ruby in a day. API: claude-fable-5 at $10/M input, $50/M output. Free on Pro/Max/Team plans through June 22.
Payment Required
Launch Team
Anthropic just made their most powerful model available to the public for the first time.
What it is: Claude Fable 5 is a Mythos-class model, the same tier of AI that was locked behind Project Glasswing since April and only accessible to cybersecurity partners like Apple, Google, Microsoft, and JPMorgan. Fable 5 is the public version with safety classifiers layered on top.
What makes it different: Most model launches are either locked down with hard refusals or released wide open. Fable 5 does something new. When you hit a sensitive area like cybersecurity, biology, chemistry, or model distillation, your query quietly routes to Opus 4.8 instead. You still get a response, just from a slightly less capable model. No walls. This triggers in less than 5% of sessions.
What it can actually do:
Stripe used it to migrate 50 million lines of Ruby in a single day. That's a two-month team project compressed into hours
Scores highest among frontier models on Cognition's FrontierCode eval, even at medium effort
Beat Pokémon FireRed using only raw screenshots with zero helper tools
Top scores on Hebbia's finance benchmark for document reasoning, chart interpretation, and problem solving
The unrestricted Mythos 5 version accelerated drug design by 10x and autonomously conducted genomics research that outperformed a model published in Science
Who it's for: Developers building on the API (model string: claude-fable-5, $10/M input, $50/M output). Pro, Max, and Team subscribers get free access through June 22 before it moves to usage credits. Cybersecurity and biomedical teams can apply for the trusted access program to get full Mythos 5 without classifiers.
The key thing here isn't just the benchmarks. It's that the gap between Fable 5 and everything else gets wider the harder and longer the task is. That's a fundamentally different scaling behavior than what we've seen from previous models.
