Meta launches Muse Wonder AI models for agents

Meta released Muse Wonder and Muse Wonder Full, its most capable AI models yet, designed for personal and professional agent tasks including insurance claims, coding, law, finance, and health. Two new features, Active Memory and Active Focus, carry context across conversations and help the model recover from errors. Trained at Meta's Prometheus data center, the models support a 1 million-token context window mixing text, video, audio, and images. Muse Wonder Full outperformed rivals on legal and coding benchmarks but trailed Claude Opus 5.5 on health and computer-use tests. Developers can access Muse Wonder today via the Meta Model API.
