Anthropic has released two new AI models, Mythos 5.2 and Fable 5.2, stating that they feature enhancements in programming, reasoning, and vision, among other areas. Notably, Anthropic has lowered Fable's input token price from $10 to $8 per million tokens, increased response speed by 30%, and introduced support for a Zero Data Retention (ZDR) policy. This release comes at a time when a report from third-party evaluation firm METR suggests the lab may be nearing recursive self-improvement (RSI).
