What Muse Wonder is

Per MetaMeta calls Muse Wonder and Muse Wonder Full “our most capable models to date,” built for agentic tasks in personal and professional settings and extending the work behind Muse Spark.1 Two features Meta highlights:1

  • Active Memory: carries relevant information across conversations.
  • Active Focus: helps the model keep working on hard tasks, recover from errors, and ask for clarification or check in before important actions.

Meta’s research post names three of its evaluations: Harvey’s Legal Agent Benchmark, FocusBench and SWE-Marathon (coding). It says Wonder Full beats the Muse Spark 1.3 trend on unfamiliar tasks, which it puts down to a larger base model.2
