Meta releases Muse Wonder and Muse Wonder Full, its first frontier models
Meta Superintelligence Labs has released two models that are larger and stronger than Muse Spark and have a one-million-token context. Muse Wonder is available through the Meta API at $4 per million input tokens and $20 for output; Wonder Full is limited to Muse Code subscribers. Meta's own tests put them on par with the newest models from OpenAI and Anthropic, though an independent index still ranks Claude Opus 5.5 first.
