Meta released Muse Glimmer on 10 August 2026, a 30-billion-parameter open-weight agentic model published under an Apache 2.0 licence. Quantised to under 20GB, it runs local agents on a single 24GB consumer GPU or a Mac. Meta also said open weights for its frontier model, Muse Spark 1.2, follow in the coming weeks.

The need for at least 24GB of VRAM to run Muse Glimmer is just one factor that makes its value challenging to determine.

We’re on a journey to advance and democratize artificial intelligence through open source and open science.
