Meta's October 12, 2026 launch of Muse Wonder and the stronger Muse Wonder Full variants established the new frontier line for agentic workflows, including long-horizon coding, memory-intensive tasks, and multimodal inputs with a 1M-token context window. The initial models, trained at the Prometheus data center with Active Memory and Active Focus features, achieved competitive benchmark scores behind Claude Opus 5.5 but ahead of prior Muse Spark releases, shifting trader focus to the pace of point-release updates. Historical one-month intervals between Spark 1.1–1.3 releases suggest a potential Muse Wonder 1.1 window in November, though Meta has prioritized consolidating the Wonder family over rapid iteration and no official timeline or preview has emerged.
