Meta releases Muse Glimmer open model, backed by Zuckerberg's 'AI for everyone' manifesto

Meta released Muse Glimmer, a 30B open-weight AI model that can be downloaded and run on personal hardware, contrasting with its more powerful Muse Spark model which remains behind the company's proprietary APIs. The release was accompanied by a letter from Mark Zuckerberg arguing that AI should be available to everyone rather than controlled by a few labs. The initiative reflects Meta's push to position itself as a champion of open AI development, though the company continues to maintain proprietary versions of its most capable models.
