A focused, 24-hour hands-on review of Anthropic’s Claude Fable 5 and Mythos 5, comparing performance, pricing, safeguards, and real‑world coding impact.
– Model split: Mythos and Fable share weights; Mythos has safeguards lifted for vetted partners while Fable returns Opus 48 on restricted queries.
– Performance & cost: Mythos tops Cursor Bench but Fable costs $10/1M input and $50/1M output; free access ends June 22.
– Practical impact: fixed production bugs, accelerated app scaffolding and code reviews; raises questions about compute limits, access equity, and safety.
Quotes:
This is the next paradigm shift.
We’re just going to burn money, baby.
Two people working 16 hours produced the equivalent of 72 working days of work when they used Mythos.
