[D] How does Amazon’s AI generated review summarizer work?

If it’s using generative models, there’s no way their gen AI model is using all the reviews, passing it through the model, and summarizing it.

So for products with a high number of reviews, what do you think they’re doing? Finding common words between reviews of the same rating, then summarizing a subset of reviews? How does Amazon know how to rate something like “Quality” as green or yellow or gray for neutral?

I also noticed the YouTube comment section …
