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.?

— Mark Zuckerberg · 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.

Some people argue that we must close our models to prevent China from gaining access to them, but my view is that this will not work and will only disadvantage the US and its allies. Our adversaries are great at espionage, stealing models that fit on a thumb drive is relatively easy...?

— Mark Zuckerberg · Jul 23, 2024
Context: A strategic argument, not yet adjudicable: whether openness or closure better serves US advantage stays contested. But the premise that closing US models would not deny China frontier capability keeps gaining evidence — Moonshot's Kimi K3, DeepSeek's V4-Flash and Alibaba's Qwen3.8-Max are native Chinese capability, not derivatives of leaked US weights, though Qwen shipped proprietary before its August open-weight release, cutting the other way.
