Anthropic launches Fable 5.2 and Mythos 5.2: 30% faster, cheaper, loyalty-based resets
bcherny · x · 2026-11-10
Anthropic released Claude Fable 5.2 and Mythos 5.2, targeting daunting technical challenges with gains in coding, reasoning, and vision. Outputs are up to 30% faster than the 5.1 models, priced at $8/M input and $40/M output tokens. New perk: Fable resets scale with tenure — 1 for <6 months, 2 for 6–12 months, 3 for 12+ month subscribers. Boris Cherny framed it as rewarding longtime users.
