Five people familiar with the matter told Reuters that Amazon's new Alexa, which is expected to be released in October ahead of the U.S. holiday season, will be powered primarily by Anthropic's Claude artificial intelligence models rather than its own AI. Amazon intends to charge $5 to $10 monthly for its new ""Remarkable"" version of Alexa, which would employ strong generative AI to respond to complicated queries. The ""Classic"" voice assistant will remain free of charge.
