Meta Superintelligence Labs released Muse Spark, a natively multimodal AI model that combines visual and language reasoning with tool-use capabilities and multi-agent orchestration. The model is immediately available through Meta AI app and select partner APIs, with competitive performance claimed across multimodal perception, reasoning, and health applications including visual troubleshooting and medical explanations developed with 1,000+ physicians. This marks Meta's major re-entry into frontier AI competition after a nine-month infrastructure overhaul, positioning against OpenAI's GPT and Google's Gemini with plans to open-source future versions.
