Meta on Wednesday launched a new artificial intelligence model named 'Muse Spark', following a major overhaul of its Super Intelligence Labs unit. According to a company blog post cited by AFP from San Francisco, the lab has rebuilt Meta’s AI framework from scratch over the past nine months. The model, currently available only in the United States, is described as smaller but faster, capable of solving complex questions in science, mathematics, and health.

'Muse Spark' succeeds Meta’s earlier model 'Llama 4' and will be integrated across Meta’s AI applications, smart glasses, and platforms such as Facebook, Instagram, WhatsApp, and Messenger. It is the first in Meta’s new 'Muse' series, with work already underway on its next generation.

The launch follows significant leadership and structural changes within Meta’s AI division. CEO Mark Zuckerberg reorganized the team after 'Llama 4' lagged behind competitors from China, France, and the United States. He appointed Scale AI co-founder Alexandr Wang to lead the new lab and recruited senior executives from rival firms including OpenAI, Anthropic, and Google.
