Summary:

• **What is Sequential Attention?** Google researchers created a new way to help AI models work faster and use less computer power. Instead of the AI looking at all information at once, sequential attention makes it look at information step-by-step, kind of like how you read one word at a time instead of trying to understand a whole page at once.

• **Why Does This Matter?** This new method helps AI models give accurate answers while using fewer computer resources, which means they can run on smaller devices and use less electricity. It's like making a robot smarter but also lighter and easier to carry around!
