Meta abandons open source for Muse Spark

Meta has officially launched Muse Spark, a sophisticated multimodal AI model developed by the newly established Meta Superintelligence Labs. This release represents a significant strategic pivot, as the company has moved away from its traditional open-source approach to keep this high-performance model proprietary. Designed to achieve "personal superintelligence," the system features a novel Contemplating mode that uses multiple agents to solve complex problems in parallel. The model excels in specialized domains like health and medical reasoning, yet current benchmarks show it still trails competitors in advanced coding tasks. Muse Spark is currently being integrated across Meta’s major social platforms, including WhatsApp, Instagram, and Facebook, as well as their smart glasses. This ground-up rebuild of Meta's AI stack emphasizes computational efficiency, matching the power of previous models while utilizing significantly less processing energy.
