Meta returns to AI front ranks with its new Muse Wonder models

what happened

Meta Platforms introduced Muse Wonder and Muse Wonder Full, describing them as the company’s most capable models so far. Meta shares rose more than 3% on Monday after the announcement. MarketWatch, which is operated by Dow Jones & Co., said the launch follows a sweeping overhaul of Meta’s AI efforts last year and represents the company’s bid to regain a leading position in the industry.

The lighter Muse Wonder is available now to developers through the Meta Model API and Muse Code, while Muse Wonder Full is offered to Muse Code subscribers. Meta CEO Mark Zuckerberg described the products as a new group of frontier models designed for personal and professional work carried out by AI agents. They include expertise in areas such as law, finance and health. Meta’s benchmark results show Muse Wonder Full ahead of leading OpenAI and Anthropic models in memory retention, financial analysis and long-horizon coding, although competing systems remain stronger in other categories.

The release follows the rapid adoption of Meta’s Muse agent, which exceeded 5 million downloads in September. Meta plans to use Muse Wonder in future Muse experiences and eventually extend the upgraded intelligence to every user, while access to Muse currently requires a paid subscription. Baird analyst Colin Sebastian called the launch a strong endorsement of Meta’s AI capabilities and its Meta Superintelligence Labs team. He said the models can generate revenue directly through Muse Code subscriptions and Meta Model API usage, while also helping Muse and other applications compete, broaden total addressable market opportunities and support new business models. Sebastian added that Instagram and Facebook could gain new user features and improved ad recommendations. Meta stressed that private exchanges with Muse will remain separate from the systems used for advertising. Before the official launch, the model was known internally as “Watermelon.” BofA analyst Justin Post wrote in September that the release could deliver frontier-level capabilities and become a long-term catalyst for Meta shares.

why it matters

The launch highlights Meta’s effort to monetize AI through subscriptions and API access while strengthening its own products. It also gives investors another point of comparison with OpenAI and Anthropic.
