The reporting

A neutral summary of the key facts most outlets agree on, drawn from reporting across the political spectrum.

Meta on Monday released Muse Glimmer, a 30-billion-parameter open-weight model designed to run AI agents locally on high-end laptops and PCs. The model is available under the Apache 2.0 license, allowing users to download, modify and deploy its weights rather than access it only through Meta-run cloud services. CEO Mark Zuckerberg also said Meta will open the weights for Muse Spark 1.2, its more powerful model, in the next few weeks. In a more than 6,000-word essay, Zuckerberg argued for free or low-cost access to high-powered AI models.
