Amazon is increasingly relying on generative AI to fundamentally transform the shopping experience. Personalized product descriptions and dynamic recommendations are just the tip of a comprehensive AI strategy.
The integration of artificial intelligence enables Amazon to customize product information. For example, if a customer is looking for healthy food, attributes such as “gluten-free” are automatically highlighted in the product descriptions. This personalization is done by a sophisticated system of two large language models (LLMs): one generates the content, while a second “challenger” LLM checks and optimizes it for accuracy.
At the same time, the company is expanding its AI portfolio with the new “Interests” tool, which is currently available as a beta version. It allows users to make natural language search queries such as “brewing tools for coffee lovers under €100”.
The dynamic recommendations adapt to the context – for example, “gift boxes for Mother’s Day” are suggested based on purchase history. Over 125 million customers left more than 1.5 billion reviews in 2024 alone, which Amazon analyzes using AI to identify trends and simplify decision-making.
In the fashion industry, Amazon uses AI to optimize size recommendations. The system analyzes anonymized purchase data and reviews to suggest suitable clothing sizes. According to internal data, customers who follow these recommendations are more likely to keep their purchases – which reduces the return rate.
