Meta's New AI Muse Wonder Can Remember You for Months

Meta just launched its first serious competitor to the most powerful AI models from OpenAI and Google. It's called Muse Wonder, and unlike previous lightweight versions, this one is big, expensive, and designed to handle complex jobs like writing code or holding long conversations. The company says it scores as well as top rivals on tests, and it costs roughly the same as premium models: $4 per million words you send, $20 per million it writes back. That's like paying for a super-smart assistant by the word.

The real story is memory. Most AI forgets what you said yesterday. Muse Wonder is built to remember your preferences, past conversations, and important details for months. Meta calls this "active memory," and it's a big deal if you want an AI that acts like a personal assistant—one that knows your schedule, your favorite restaurants, or how you like your emails written. A research scientist said they worked hard to make it remember what matters to you over long periods.

But there's a catch. The most capable version, Muse Wonder Full, is only available to people who subscribe to Meta's coding tool, Muse Code. Regular users and developers can only access the slightly smaller Wonder model through an API (a way for apps to connect). So if you're not a coder, you might not get the full experience yet.

Still, this marks a turning point for Meta. After restructuring its AI lab last year, the company is finally shipping a frontier model—trained in a new Ohio data center. It's a clear signal that Meta wants to compete not just on social media, but on the AI that could soon run your daily digital life.
