Meta introduced Muse Wonder and Muse Wonder Full on October 12, 2026, expanding its AI lineup with models designed to carry out personal and professional tasks.
The company describes them as its most capable models to date, building on the foundations of Muse Spark. Muse Wonder is available through the Meta Model API and Muse Code, while Wonder Full is offered through eligible Muse Code subscriptions.
Memory and persistence are central features
Meta highlights two capabilities: Active Memory and Active Focus.
Active Memory is intended to carry relevant information across conversations. Active Focus is designed to help the models continue through difficult tasks, try alternative approaches, recover from errors, and seek clarification when needed.
Meta positions these features around work that requires several steps rather than a single response. The capabilities are company descriptions, rather than findings from independent testing presented here.
Tools for developers and longer workflows
Meta’s developer materials describe support for coding, long-running agents, and computer use. The company says Muse Wonder can plan work, delegate parts to other agents, and use tools to complete complex workflows.
Both models have a listed one-million-token context window, allowing substantial material to be supplied within a task.
Muse Wonder API pricing is US$4 per million input tokens and US$20 per million output tokens, with cached input priced at US$0.20 per million tokens. These are usage charges rather than monthly subscription prices.
Different access options
Wonder Full is available in Muse Code’s Power Usage and Maximum Usage plans. Meta lists these at US$50 and US$200 per month, respectively.
Meta also plans to bring Muse Wonder into its Muse agent, starting with subscribers. The launch announcement does not give a specific date for that rollout.
For developers evaluating the release, the practical distinction is access: Muse Wonder supports API-based projects, while Wonder Full is currently accessed through Muse Code subscriptions.
