New MeZO method enables on-device AI fine-tuning without backpropagation

Researchers have developed a new method called Memory-efficient Zeroth-Order Optimization (MeZO) for fine-tuning AI models on edge devices. This technique bypasses the need to store intermediate activations and optimizer states, which are required by traditional backpropagation methods. MeZO uses forward evaluations to estimate gradients, allowing larger models to fit within the limited memory of edge devices, though it may require more time for fine-tuning. AI
