Earlier quoted context omitted.
Amazon also uses Claude under the hood for their "Rufus" shopping search assistant which is all over amazon.com. It's kind of funny, you can ask Rufus for stuff like "write a hello world in python for me" and then it will do it and also recommend some python books.
Are you sure? While Amazon doesn't own a "true" frontier model they have their own foundation model called Nova. I assume if Amazon was using Claude's latest models to power it's AI tools, such as Alexa+ or Rufus, they would be much better than they currently are. I assume if their consumer facing AI is using Claude at all it would be a Sonnet or Haiku model from 1+ versions back simply due to cost.
I work for Amazon, everyone is using Claude. Nova is a piece of crap, nobody is using it. It's literally useless.
I haven't tried the new versions that just came out though.
