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

Aug 10 (Reuters) - Meta CEO Mark Zuckerberg called for lower U.S. barriers for open-source AI models to compete with Chinese rivals as the social media giant released a new open-weight model on Monday.

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

It comes as the social media giant seeks to strengthen its position after forming a costly, new superintelligence team last year to propel itself back into the high-stakes AI race.

U.S. President Donald Trump's administration told AI developers earlier this month that it will not put open-weight AI models through voluntary safety tests, according to two sources familiar with the discussions.
