Meta's rapid iteration on the Muse Spark series, with version 1.3 launching September 2 via the Meta Model API and Muse Code, anchors current trader sentiment around the timing of a 1.4+ release. The update delivered measurable gains in long-horizon agentic tasks and coding efficiency, using roughly 20% fewer tool calls and 25% fewer tokens than 1.2 while adding better calibration for irreversible actions. This follows 1.2 in early August and 1.1 in July, reflecting Meta Superintelligence Labs' push into competitive frontier multimodal reasoning against OpenAI and Anthropic offerings at similar pricing. Key upcoming signals include CEO Mark Zuckerberg's mentions of a larger "Watermelon" model and open-weights releases, alongside ongoing safety testing for advanced reasoning modes that could accelerate or delay the next major version.

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.
The primary resolution source for this market will be official information from Meta, with additional verification from a consensus of credible reporting.
