Meta Platforms released on August 10, 2026 Muse Glimmer, an open-weight AI model with approximately 30 billion parameters, capable of running locally on a consumer machine with a single graphics card. Meta’s more advanced system, Muse Spark, remains proprietary and accessible only through a paid API, although the company plans to release open weights for Muse Spark 1.2 in the weeks following Glimmer’s debut. Mark Zuckerberg accompanied the announcement with a 14-page essay titled « The Future is for Everyone », advocating for the wide distribution of advanced AI capabilities. Meta shares rose nearly 3% in premarket trading after the announcement. This two-track strategy allows Meta to expand its ecosystem with Glimmer while maintaining a monetizable product with Spark.
