Meta has introduced a new AI model, Muse Glimmer, designed to run agentic tasks on a Mac or PC using a single graphics card, as CEO Mark Zuckerberg renewed his support for open-weight artificial intelligence.
The model is smaller than leading systems developed by rivals but is aimed at growing demand for AI tools that can operate directly on users’ devices. Zuckerberg said Meta was also working on larger models.
In a 14-page essay titled The Future is for Everyone, Zuckerberg argued that AI development should be widely distributed rather than concentrated among a small number of companies. His comments come as businesses increasingly consider open-weight models as a cheaper and more customisable alternative to closed systems from companies such as OpenAI and Anthropic.
Meta also plans to release the weights of Muse Spark 1.2, its most advanced model developed by the company’s superintelligence team.
Chinese AI companies have emerged as strong competitors in the open-weight space, with models from Moonshot, Alibaba and DeepSeek challenging leading US systems. Major US developers including OpenAI, Anthropic and Google continue to focus largely on closed models.
Zuckerberg also announced a $1 billion fund to support communities affected by Meta’s expanding data-centre infrastructure, amid growing opposition to data-centre projects in the United States.
Meta is expected to spend up to $145bn this year on AI infrastructure. Zuckerberg said the US needed to reconsider policies governing data use and AI model distillation to help American companies remain competitive in open-weight AI.
He also said Meta would establish a governance system allowing independent directors to approve safety criteria for releasing AI models, while arguing that US companies face greater restrictions on training data than some foreign competitors.
