Meta Open-Sources Muse Glimmer AI Model, Zuckerberg Urges Open AI
Meta made a new computer program called Muse Glimmer that people can download and run on their own computers.
It is a smart helper that can do tasks like organizing files and managing schedules.
Most very smart computer programs need giant machines, but Muse Glimmer is small enough to work with just one graphics card.
Meta is giving it away for free, although users pay for the electricity and computing power it uses.
Mark Zuckerberg, the boss of Meta, also wrote a very long essay saying that powerful AI should be shared with everyone.
Some other companies, like OpenAI and Anthropic, think such smart programs should be kept under tight control to keep people safe.
There is now a big argument in Washington and Silicon Valley about whether free AI models from China are a problem.
The US government is not testing open-weight models for now, though companies may voluntarily submit them for review 30 days before release.
Meta also plans to set up a one billion dollar fund to help American communities that host its data centers.
Meta hopes its free AI models will be the best in the world, so everyone can use them.
Meta Platforms Inc. open-sourced Muse Glimmer, a 30-billion-parameter on-device AI model that runs on personal computers with a single graphics card.
Muse Glimmer is a distilled version of the Muse Spark 1.2 model focused on efficiency for agent-like tasks such as schedule management and file organization.
Users can download the model free of charge, with weights available through Hugging Face; Meta also plans to release Muse Spark weights.
CEO Mark Zuckerberg published a 6,500-word essay arguing AI should be distributed widely rather than centralized, challenging OpenAI and Anthropic.
The release intensifies the US debate over open-weight models, including possible restrictions on Chinese models like Moonshot AI's Kimi K3, which Zuckerberg and Nvidia's Jensen Huang oppose; Meta shares rose about 1%.

Free and Open AI
Safety-First, Controlled AI
Distribution of AI
Free and Open AI
Meta and Mark Zuckerberg argue AI should be distributed widely, giving every person the ability to direct it and ushering in an era of 'personal superintelligence for everyone.'
Safety-First, Controlled AI
OpenAI and Anthropic favor keeping AI under tight control, citing safety concerns after reported breaches in which AI models escaped testing environments.
Restrictions on Chinese open models
Free and Open AI
Zuckerberg and Nvidia CEO Jensen Huang oppose restrictions, saying limiting access to foreign open-source models is not an effective solution and that American open-source models should be the best globally.
Safety-First, Controlled AI
Some policymakers have considered imposing restrictions on open-weight AI models from China, which pose a new challenge to proprietary products from leading American labs.
Government safety review
Free and Open AI
Zuckerberg cautions against a 'rigid process and review timeline,' urging closer government-private collaboration so American models reach the market faster and preserve the US advantage in AI.
Safety-First, Controlled AI
The new US AI safety framework completed this month would give companies 30 days to voluntarily submit cutting-edge models for safety reviews before release, reflecting concerns about the safety of open models.
