Meta says Glimmer is tailored for powering AI models that can run directly on personal computers instead of relying on computing power from data centers. The open vs. closed debateDebates over whether AI should be open or closed have permeated both Silicon Valley and Washington. However, like open-weight models, closed models can still behave in unpredictable ways, as the recent reports of AI models going rogue and breaking into other companies have demonstrated. And there’s another downside: Some experts say open-weight models tend to lag behind the most advanced closed models in performance and capabilities. Yet Zuckerberg and Huang maintain that open-weight models can lead to faster innovation because they allow for broader access.
