Meta announced two AI models on Monday, VentureBeat reported: Muse Wonder and Muse Wonder Full, built for agent work like coding. Meta said Muse Wonder is available through its Model API and its Muse Code coding assistant. Full is open only to Muse Code subscribers. VentureBeat said neither model can be downloaded, and that the API costs $4 per million input tokens and $20 per million output tokens (tokens are small chunks of text). It said outside tester Artificial Analysis scored Full at 56 and Muse Wonder at 52, against 58 for Claude Opus 5.5. Vercel said it added Muse Wonder to its AI Gateway the same day.
Meta has not said whether Full will come to the API. Meta said a full safety report is coming soon, with no date. The sources differ on inputs: VentureBeat lists text, images, audio and video, while Vercel lists text, images and PDFs. Meta also said Muse Wonder will soon power its Muse app, first for subscribers.
Buyers can test the standard model now, through Meta or Vercel, at a listed price. The stronger model sits inside Muse Code, so the sources show no way to call it from your own product.
