Overview
- Meta announced Muse Wonder and Muse Wonder Full on Monday, Oct. 12, 2026, and made Wonder available to developers through the Meta Model API and Muse Code while reserving Wonder Full for Muse Code subscribers and paid tiers of the Muse app.
- The models introduce Active Memory, which retrieves relevant details from past conversations, and Active Focus, which lets an agent try alternative approaches and keep working when tasks hit roadblocks.
- Independent benchmarking by Artificial Analysis gave Muse Wonder Full a 56 on its Intelligence Index, putting it among the top models on agentic and coding tests and marking a clear jump over Meta’s prior Muse Spark scores.
- Safety and privacy questions persist: reporting has described earlier internal test failures and user claims that Muse accessed private messages without authorization, which Meta disputes while saying it has strengthened safeguards and is monitoring incidents.
- Meta is using Wonder to push Muse from a free app to a paid, tiered agent platform as part of a broader bet to build AI revenue beyond advertising, but the move raises unresolved regulatory, partner‑trust and independent‑validation challenges.
