Notable: frontier-lab developer (Meta). Meta says Muse runs on 'Muse Spark' without a version number, so it is not mapped to a specific muse-spark-1-x id. Meta's 2026-10-12 Muse Wonder post says Muse Wonder 'will soon power experiences in Muse', rolling out first to subscribers — once confirmed live, muse-wonder could be added. Announcement updated 2026-09-30. Separate from the July 2026 Meta AI app task features (Muse Spark 1.1). Launched in the US and Canada; Japan 2026-10-23 (first market outside North America, with Mercari, Money Forward ME and Ticket Pia connectors) and Singapore 2026-10-28 (Shopee, Grab, Singapore Airlines and others).
