Jassy added that Amazon continues to “re-architect the brain” of Alexa with “a new set of foundation models” that the company plans to reveal “in the near future.”

Amazon, which first announced that it’d revamp Alexa with generative AI technologies in 2023, is said to be replacing its own Alexa-powering models with Anthropic’s after encountering technical challenges. (Amazon is a major investor in Anthropic.) At one point during the Alexa redesign, the unreleased, upgraded assistant reportedly struggled to turn on smart lights and took up to six seconds to respond to queries.
