Imagine having a team of tiny AI experts living inside your smartphone, ready to tackle any task you throw at them. That's the idea behind MobileExperts, a groundbreaking new framework that could revolutionize how we interact with our devices. Instead of relying on single, often clumsy virtual assistants, MobileExperts creates a dynamic team of specialized agents, each with its own skills and knowledge. These agents learn by doing, exploring your phone's interface and building up a toolkit of reusable code blocks, like building with digital LEGOs. This innovative approach significantly reduces the processing power needed, making it faster and more efficient. They then collaborate through a clever two-tiered planning system, breaking down complex tasks into smaller, manageable chunks. One layer focuses on dividing the overall task among the team, while the second layer creates a step-by-step plan for each agent. This collaboration, combined with a shared memory pool where agents can store and retrieve information, allows them to tackle complex, multi-step operations. Tests show that MobileExperts outperforms current mobile AI systems, especially in handling tricky tasks that require planning and adaptation. This points to a future where our phones become truly intelligent partners, anticipating our needs and seamlessly executing complex actions, from managing social media to booking travel, all while sipping power efficiently.
