Meta’s new model boost

Meta has rolled out Muse Spark, its first major artificial intelligence model under Chief AI Officer Alexandr Wang, and tied the push to higher output inside the company. (about.fb.com) Meta announced Muse Spark on April 8 and said the model will power a faster Meta AI assistant across WhatsApp, Instagram, Facebook, Messenger, and its smart glasses in the following weeks. CNBC reported the model was built by Meta Superintelligence Labs, the group Wang leads after joining in June 2025. (about.fb.com) (cnbc.com) Wang joined Meta in June 2025 as the company’s first Chief AI Officer. His move followed Meta’s $14.3 billion investment in Scale AI, which gave Meta a 49% stake and brought Wang into the company’s new superintelligence effort. (meta.com) (computerworld.com) A large language model is the prediction engine behind a chatbot: it studies huge amounts of text, images, and other data, then guesses the next useful answer. Meta said Muse Spark is “small and fast by design,” while still able to handle questions in science, math, and health. (about.fb.com) (cnbc.com) The productivity figures Meta is citing line up with outside research that has tracked the same kinds of workplace tasks. Stanford Human-Centered Artificial Intelligence’s 2026 AI Index said studies have found gains of about 26% in software development and 14% to 15% in customer support when companies deploy generative artificial intelligence tools. (hai.stanford.edu) Those numbers have become central to how companies sell artificial intelligence internally: not as a separate product, but as a tool folded into coding, support, and other routine work. Stanford’s 2026 AI Index said 70% of organizations now use generative artificial intelligence in at least one business function, up as adoption spread through 2025. (hai.stanford.edu) Meta’s release also marks a break from the company’s recent identity in artificial intelligence. Bloomberg and CNBC both reported Muse Spark is a closed model, unlike Meta’s earlier Llama strategy, and Meta is considering offering access to developers through an application programming interface, or software connection. (bloomberg.com) (cnbc.com) That shift follows a rough stretch for Meta’s earlier models. CNBC said the company changed course after the debut of its Llama 4 family failed to win over developers, and Computerworld reported Meta had been trying to close performance gaps with OpenAI and Anthropic before Wang arrived. (cnbc.com) (computerworld.com) Meta is presenting Muse Spark as the first output of a rebuilt artificial intelligence stack, not the finished product. The company said the next generation is already in development, which means the real test is whether the internal productivity gains it cites turn into products people use outside Meta’s own walls.
