Meta has taken a side in the debate over whether AI models should be open or tightly controlled, with CEO Mark Zuckerberg favoring the former. On Monday, the tech giant launched a new “open-weight model” called Glimmer, which Meta says is tailored for powering AI models that can run directly on personal computers instead of relying on data center computing power. Zuckerberg also published a manifesto outlining his vision, writing, “Rather than centralizing superintelligence, we should distribute it widely and give every person the ability to direct it.” The debate has permeated Silicon Valley and Washington, with closed models generally thought to be more advanced and closely monitored, though they can still behave unpredictably. Open models give developers freedom to build their own products, potentially making providers indispensable to businesses. Nvidia CEO Jensen Huang also supports open-weight models, and the chip giant says companies like Uber and Zoom are using its open models. Meta previously had a popular open-weight model called Llama but late last year shifted to developing its own closed-source model called Spark to compete with OpenAI and Anthropic. Chinese models from Moonshot and DeepSeek are also open weight, raising questions about an edge. Experts say open-weight models tend to lag behind advanced closed models in performance, but Zuckerberg and Huang maintain they lead to faster innovation. Zuckerberg argued society shouldn’t hand a select few companies the keys to create, control and distribute these tools, adding, “There is no technological solution that can align with
