Meta's promised Muse Spark open weights are over a month late and counting
RishiFurfox · reddit · 2026-09-16
A Reddit user points out that Meta promised to release Muse Spark weights on August 10, but over a month later — despite the model moving from Spark 1.2 to 1.3 — nothing has shipped.
The post highlights the irony: Zuckerberg argued models couldn't be delayed "even a month" due to competition with China, and argues that logic applies equally to the open-weights race, since Chinese models are open. The author asks whether Meta has offered any explanation, which version will ship, or whether regulatory-capture rhetoric means the weights may never come.
