Meta releases its first frontier model, Muse Wonder

Meta's Superintelligence Lab released two new models, Muse Wonder and Muse Wonder Full, calling them the company's first frontier models. According to tests published by Meta in the model card, the two models are comparable in benchmark scores to Fable 5.1 and GPT-6 Astra. When accessed via the Meta Model API, Wonder costs $4 per million input tokens and $20 per million output tokens, roughly comparable in cost to GPT-6 Sol or Opus 5.5; Wonder Full is only available to Muse Code subscribers and is not available via API. Both models will also power the Muse agent, with Meta emphasizing its "proactive memory" capability, claiming that Muse Wonder scores higher than Fable, Opus, and Astra on MemoryBench.
