Meta’s Meta Superintelligence Labs has driven the Muse Spark series with an unusually rapid cadence, launching version 1.1 in July 2026, 1.2 in early August, and 1.3 on September 2 with major gains in long-horizon agentic workflows and coding efficiency—roughly 20% fewer tool calls and 25% fewer tokens than its predecessor on internal benchmarks. The model family powers Meta AI across apps and the Meta Model API while emphasizing cost-efficient performance that competes with higher-priced frontier systems from OpenAI, Anthropic, and Google. Mark Zuckerberg has publicly flagged open-weight releases “coming soon” alongside a larger next-generation model codenamed Watermelon, creating near-term catalysts that could clarify timelines for 1.4+. Traders should monitor official Meta announcements, API updates, and credible benchmark reports for signals on release windows or capability thresholds that would resolve the market.

This market will resolve to "Yes" if Meta's next Muse Spark model (1.4+) is made available to the general public between market creation and the specified date (ET). Otherwise, this market will resolve to "No".
A qualifying model must have a name or model identifier that includes "Muse Spark" and be designated as version 1.4 or higher, regardless of capitalization, hyphenation, spacing, or surrounding prefixes, suffixes, dates, or descriptors. For example, a version 1.4 or higher named in the same manner as Muse Spark 1.2 or Muse Spark 1.3 would qualify, including a new whole-number generation such as Muse Spark 2, while models whose name does not include "Muse Spark" or which retain a version designation below 1.4, such as Muse Spark 1.3 (released September 2, 2026, including any of its reasoning modes, open-weight re-releases, rollouts, promotions, or snapshots), Muse Glimmer, or Muse Image, will not qualify.
A qualifying model must be launched and publicly accessible, including via open beta or open rolling waitlist signups. A closed beta or any form of private access will not suffice. The release must either be clearly defined and publicly announced by Meta as accessible to the general public, or otherwise be made publicly accessible and explicitly labeled on the company's official website. Labeling errors, placeholder text, or version names displayed on the website that do not correspond to a model that is actually accessible to the general public will not qualify.
