The US tech giant on Monday launched Muse Glimmer, a 30-billion parameter open-weight model light enough to run locally on personal computers, while also announcing plans to release the weights of its latest flagship Muse Spark 1.2 model. [Meta CEO Mark Zuckerberg](https://sc.mp/qkphp?utm_source=copy-link&utm_campaign=3310893&utm_medium=share_widget)said the company would resume releasing open-source models with the goal of “delivering personal superintelligence to billions of people and small businesses”. The releases positioned Meta directly against top Chinese open-weight models, offering a competitive performance without the geopolitical baggage, analysts said. “Many American users and companies will prefer to build with American models if there’s a good open-source version,” said Kyle Chan, a fellow at the Brookings Institution. “They would prefer not to deal with compliance risk, reputational risk and other unknowns when it comes to Chinese models.” Meta’s new offerings compete directly with top Chinese alternatives across both the flagship and lightweight tiers.
