**Seattle, WA** – Amazon’s innovative “Just Walk Out” technology, which allows shoppers to grab items and leave without waiting in line, is getting a significant boost with the introduction of a new multi-modal AI system. This next-generation system, dubbed Just Walk Out 2.0, uses a foundation model (FM) trained on data from multiple sources like cameras, weight sensors, digital floor plans, and product images to generate accurate shopping receipts.

The previous version of Just Walk Out relied on a modular architecture, breaking down the shopping experience into separate tasks. While effective, this approach required significant engineering efforts to address complex shopping scenarios and new store formats. The new multi-modal FM, however, learns from diverse data sources, enabling it to handle a wider range of shopping behaviors and store environments.

“This is a major step forward for Just Walk Out,” said Tian Lan, Principal Scientist at AWS and leader of the Just Walk Out 2.0 development. “The multi-modal AI system allows us to move away from human-defined components and build a simpler, more scalable system that can be trained end-to-end.”

The new AI system features several key improvements, including:

* **Enhanced Accuracy:** The multi-modal FM consistently generates accurate receipts even in complex situations.
* **Improved Generalization:** The system can handle new store formats, products, and customer behaviors, making it suitable for a wider range of retail environments.
* **Continuous Learning:** The model automatically adapts and learns from new scenarios, ensuring high performance even as shopping habits evolve.

Amazon is committed to bringing Just Walk Out technology to more locations worldwide. The new AI system, with its increased accuracy and adaptability, significantly accelerates this goal. Retailers can now confidently deploy Just Walk Out technology, knowing it will provide a seamless and frictionless checkout experience for their customers.
