Meta launches new AI model as Zuckerberg champions open-weight push

The new model, Muse Glimmer, is smaller than leading AI models from rivals and is instead designed to run agentic tasks on a Mac or PC with a single graphics card, ‌aiming to tap demand for AI systems that run directly on people’s devices.

Meta Platforms CEO Mark Zuckerberg called for lower US barriers for open-source AI to better compete with Chinese rivals as the social media giant released a new open-weight model on Monday and said more would follow soon.
