Meta releases Muse Wonder and Muse Wonder Full frontier models

Meta introduced its first frontier-class models, Muse Wonder and Muse Wonder Full, after a 14-month overhaul of its AI efforts. The models feature Active Memory and Active Focus for long-running agentic tasks and are claimed to match or exceed select benchmarks from OpenAI GPT-6 Astra and Anthropic Claude models on coding, legal, and financial workflows. Availability is through the Meta Model API and Muse Code, with integration planned for the Muse personal agent for subscribers, marking Meta's return to the competitive frontier tier.
