Meta released Muse Wonder and Muse Wonder Full on Monday, the first Superintelligence Labs models the company is willing to compare with OpenAI's and Anthropic's best. Muse Wonder costs $4 per million input tokens and $20 per million output tokens, matching Claude Opus 5.5. Meta's benchmark results favor Muse Wonder Full, but Artificial Analysis still ranks Opus 5.5 first. The models offer persistent memory and sustained work on difficult goals, while the memory feature raises privacy concerns. Meta says a full safety report is coming soon, and Muse Wonder will reach the Muse app first for paying subscribers.
