Researchers have developed DASH, a novel differentiable architecture search framework designed to rapidly discover efficient hybrid attention mechanisms for large language models. Unlike previous methods that required extensive computational resources, DASH significantly reduces search time and token usage by relaxing discrete operator placement into continuous logits and freezing model weights. This approach consistently yields superior results compared to existing baselines and even surpasses some released models, demonstrating that high-quality hybrid attention architectures can be found in minutes on a single GPU.
