Meta to open source its most powerful AI model as it takes swipe at OpenAI, Anthropic

Meta announced it will open source its most powerful AI model, Muse Spark 1.2, by releasing its weights (the calculations and rules that determine how the AI works), and launch a new family of models called Muse Glimmer designed to run on laptops rather than expensive cloud servers. The company is positioning this move to compete with Chinese open-source AI models and rival U.S. companies like OpenAI and Anthropic, while Zuckerberg argues that U.S. policy changes are needed to help American open-source models compete globally.
