One detail in this update deserves a closer look.
Anthropic's Claude Fable 5.2 and Mythos 5.0 Are Impressive, But Be Prepared to Sell a Kidney to Afford Them - Decrypt In brief Anthropic released Claude Fable 5.2 and restricted sibling Mythos 5.2, promising stronger coding and reasoning at lower per-token prices. Anthropic released Claude Fable 5.2 and Mythos 5.2 on Monday, promising AI models that can turn a handful of instructions into working software, design physical objects, and tackle research problems that previously required teams of specialists. Anthropic's internal FrontierCode 2.0 evaluation, which measures the percentage of proposed coding changes that would be accepted into real open-source projects, put Fable 5.2 at 49.1%, compared with 32.4% for Fable 5.1. Optional fast mode can generate output up to 2.5 times faster, but doubles the rates to $16 and $80. Per Anthropic’s standards, Fable’s price is still twice the per-token price of Claude Opus 5.5, which Anthropic recommends for everyday work.
