Bloomberg reported that Meta has started charging for its Muse Spark 1.1 AI model, and the news spread on X through posts from @MikeIsaac and @nikitabier. The visible public posts frame it as a notable shift for Meta, especially given the company's recent open-model posture. What is solid here is the Bloomberg report and the posts themselves. What still depends on source context is how broad a strategy change this turns out to be.
