Meta claims new Muse Wonder AI models rival OpenAI, Anthropic. The top-end model, Wonder Full, hit 56 on the Artificial Analysis index, putting it ahead of Astra and Fable (53), though still behind Claude Opus 5.5 (58). Not everyone agrees with Meta's framing, though. Abacus. AI CEO Bindu Reddy pushed back on X, saying the model is nowhere near Fable or Astra level. The catch is access. Wonder Full is locked behind Muse Code subscriptions up to $200 a month. The version developers can actually call via API is standard Muse Wonder, which scored 52, priced at $4 input and $20 output per million tokens.
