Meta on Monday introduced Muse Wonder and Muse Wonder Full, its most advanced artificial intelligence models to date, as the company seeks to compete more directly with OpenAI and Anthropic in the AI space. The launch follows a 14-month overhaul of Meta’s AI efforts, which the company described as shifting from rebuilding foundations to pushing technological boundaries.
The new models are designed to power Meta’s personal AI agent, Muse, initially for subscribers, while the more powerful Muse Wonder Full is available to subscribers of its AI coding tool, Muse Code. Access to Muse Wonder requires a monthly subscription of $20 or $100, depending on usage levels, marking Meta’s latest effort to diversify revenue streams beyond its core online advertising business.
Meta’s shares rose approximately 4% in afternoon trading following the announcement, reflecting investor optimism about the company’s AI initiatives. The models were developed under the codename Watermelon, with a focus on improving the capabilities of personal and professional AI agents to handle real-world tasks such as booking reservations and checking availability without stalling.
Privacy and safeguards were highlighted as key features of the new models, with Meta stating that Muse Wonder offers its strongest protections to date against cyber misuse. However, these safeguards are currently available only to paid subscribers. The company acknowledged user concerns about privacy, including reports on social media that the AI agent accessed personal messages without authorization. Meta disputed these claims, attributing them to users forgetting prior authorizations, and emphasized ongoing efforts to educate users on proper app usage.
Meta’s AI chief, Alexandr Wang, noted that the company has been monitoring for agent-related incidents to address potential issues proactively. The Muse personal AI agent app, which is free to download, has already ranked at the top of Apple’s App Store since its launch last month, with subscription plans available for additional usage.
The company’s aggressive push into AI comes after CEO Mark Zuckerberg pledged billions of dollars and recruited researchers over the past year to close the gap in Silicon Valley’s intensifying AI race. Meta framed the launch as part of a broader strategy to turn its AI investments into new revenue streams, despite ongoing concerns about user privacy and data security.
