Meta Muse Wonder: pricing, benchmarks and limits - MACCUS

Meta has released Muse Wonder and Muse Wonder Full, its most advanced AI models designed for handling personal and professional tasks. Muse Wonder is available via Meta's API and in Muse Code, while the more capable Muse Wonder Full is limited to Muse Code subscribers on higher-tier plans. The models feature Active Memory for context retention and Active Focus for persistence on complex tasks. API pricing for Muse Wonder is $4 per million input tokens and $20 per million output tokens, with cached input at $0.20 and web search at $2.50 per 1,000 queries; it supports a 1,048,576-token context window with multimodal input. In benchmarks, Meta's models lead in half the tests, particularly in legal work and long-horizon coding, but Claude Opus 5.5 excels in other areas. Caveats include reliance on internal tests and limited independent verification. Safety tests show high refusal rates for cyber misuse and low mishandling of personal information. Meta recommends disabling Contributor mode for client work and urges businesses to test the model on real tasks with human oversight. As of October 12, 2026, independent benchmarks and the full safety report are pending, and country availability may vary.
