Meta Launches Muse Wonder AI Model With Paid Subscriptions

Meta introduced Muse Wonder, a new artificial intelligence model designed to power digital assistants, on Oct. 12, 2026, as the company expands efforts to generate revenue from AI services beyond online advertising. Access through the Muse personal agent app requires a monthly subscription costing $20 or $100, according to the company.

Meta describes Muse Wonder as its most advanced model for digital assistants. The company developed the system to help AI agents complete personal and professional tasks more reliably, including making dinner reservations and checking availability, according to Meta AI chief Alexandr Wang.

The release also introduces stronger safeguards against cyber misuse, Meta said in a company blog post. These protections are currently available only through the paid model, according to the company.

Wang discussed the model's development and the challenges facing AI agents in an interview on Monday. The system, internally codenamed Watermelon, was trained to respond to obstacles by attempting alternative approaches rather than stopping a task and immediately asking users for guidance.

"When you do real-world tasks, you're going to get roadblocks and you're going to get things that come up or various setbacks," Wang said.

Wang said the development team focused on helping the model adapt when tasks encounter unexpected problems. He described the training approach as an effort to make agents more capable of continuing work independently.

"We specifically tried to train the model to be able to try other approaches instead of stalling and then checking back in with the user at any time," Wang said.

The launch follows the introduction of the Muse personal agent app the previous month. The app climbed to the top of Apple's App Store after its debut, while Meta continued offering a free version alongside subscriptions for users seeking greater access, according to the source report.

Meta has also faced questions about how its AI agent handles personal communications. Some users have complained on social media that Muse accessed private messages without authorization, allegations the company has disputed.

Wang said Meta's AI team has been tracking incidents and other problems involving the agent to identify shortcomings and address them. He also said the company is working to help users better understand how permissions granted during conversations can affect the agent's actions.

"I think there are certainly instances users have authorized various communications or whatnot earlier in a conversation, and then may have forgotten about that," Wang said.

Wang said Meta is educating users about these interactions as it seeks to address concerns surrounding the product's use. The company is working to clarify how users authorize communications and manage interactions with the agent.

"To ensure that consumers can trust the product going forward," Wang said, describing the goal of the company's efforts to improve user understanding.

Meta is also making Muse Wonder available to developers through its Meta Model API, a service that provides access to the company's models. Wang said API access will cost more than the standard consumer subscriptions because the model is substantially larger and operates at the frontier of AI development.

He said the developer pricing would remain meaningfully below the rates charged for leading models from OpenAI and Anthropic, without specifying an exact price in the source report.

A more powerful version, Muse Wonder Full, will be restricted to developers using Muse Code, Meta's AI agent focused on software engineering. Access will require a subscription costing $50 or $200 per month, according to the source report.
