Tracked Statements (2)

Meta will 'soon' release open weights for its flagship Muse Spark 1.2, extending its open-weight pivot from the small Muse Glimmer to a frontier-band model.?

— Meta AI · Aug 10, 2026
Context: Still not done. Three weeks on, Meta instead shipped a newer proprietary flagship, Muse Spark 1.3, on 2 September — served through its own API and limited to partners at the top tier — and has published open weights for neither Muse Spark model. The pledge named no deadline, so it stays unverified rather than broken, but the trajectory is away from it.

We believe an open approach is the right one for the development of today's AI models, especially those in the generative space where the technology is rapidly advancing. By making AI models available openly, they can benefit everyone.?

— Meta AI · Jul 18, 2023
Context: A development-philosophy statement, not falsifiable — but measurable against Meta's conduct, which has now reversed twice. Its Muse flagship line shipped proprietary (Muse Spark 1.1 and 1.2), then in August 2026 Meta returned to open weights, releasing Muse Glimmer and pledging to open Muse Spark 1.2. The 2023 argument stands as the founding statement of the strategy Meta abandoned and has now resumed.
