Zuckerberg's Best AI Model Isn't in Meta's API. You Need a $50 Muse Code Plan to Use It

Meta released two frontier models on October 12. Muse Wonder Full, the top-performing model on Meta's scorecard, is unavailable via the Meta Model API and requires a Muse Code subscription, costing $50 or $200 monthly. The API provides Muse Wonder instead. While Muse Wonder outperforms GPT-6 Astra and Claude in memory, legal, and marathon coding tests, independent rankings still place Anthropic's Opus 5.5 at the top of the frontier AI race.
