Mark Zuckerberg unveiled Muse Wonder, which Meta says is as powerful as the latest models from OpenAI and Anthropic, marking a major step after Meta had lagged behind many rivals in AI. The company released two models: Muse Wonder, designed to be versatile and handle most tasks, and Muse Wonder Full, which Meta calls the largest and most capable model it has trained. Built to serve as a personal assistant, the model can handle long tasks spanning many days, with 'active memory' to retain context, better focus on goals, and checks before taking important actions. Meta also says it has improved safety, including resistance to adversarial instructions. The model is notably expensive to run compared with Meta's other systems, though in line with top models from OpenAI and Anthropic, and it will soon power more of the free Muse agent.
