Meta's AI app has seen significant increase in installs following the launch of its newest AI model, Muse Spark, which is its first release under Alexandr Wang, the head of Meta’s Superintelligence Labs. The new model is designed to perform well on several tasks including learning about health and reasoning, and creating websites and mini-games from prompts. The launch of Muse Spark is seen as a significant upgrade over the company's earlier Llama 4 model and is part of a wider effort to catch up with rivals like OpenAI and Anthropic. The company's mobile app and website have been upgraded with a new look and feel and allow users to switch between modes depending on the task. Despite the recent growth, Meta AI still lags behind other top model makers like Open AI's ChatGPT and Google's Gemini.
