Meta has a competitive AI model but loses its open-source identity

AI-summarised brief · reviewed before publication

Meta launched Muse Spark, a proprietary AI model, after spending $14.3 billion and rebuilding its AI stack. Muse Spark is a multimodal reasoning model that powers Meta AI, reaching over three billion users. It benchmarks well, especially in health queries, but its proprietary nature has sparked skepticism among developers, who are now waiting for a potential future open-source version. Muse Spark will debut in Meta's apps, including Facebook and Instagram, in the coming weeks.
