Meta releases open-weight Glimmer model as Zuckerberg calls for accessible AI
The new open-weight model contrasts with Meta’s proprietary Muse Spark, coinciding with a manifesto arguing against lab-controlled artificial intelligence

Meta has released Glimmer, an open-weight artificial intelligence model that allows users to download and run the software on personal hardware. This launch stands in contrast to the company’s proprietary Muse Spark model, which remains restricted to Meta’s own application programming interfaces.
The release coincides with a 6,500-word manifesto published by Mark Zuckerberg, in which he argues that artificial intelligence should be accessible to everyone rather than controlled by a small number of laboratories.
TechCrunch’s Equity podcast discussed the release and the manifesto, noting that the vision comes with certain asterisks. The episode was hosted by Kirsten Korosec, Anthony Ha, and Rebecca Bellan, who examined the implications of the open-weight model and the broader industry context.
The podcast also covered the rising energy costs associated with AI data centres. Additionally, the hosts discussed a $250 million acquisition that collapsed, resulting in allegations of fraud.
Concurrent industry developments include Twitch streamers opting out of Amazon’s AI training data and a lawsuit challenging Truth Social’s API subscription model.
