Investing.com -- Amazon (NASDAQ: AMZN ) has recently launched its revamped Alexa devices, and sources have revealed to CNBC that the advanced capabilities of these devices are powered by artificial intelligence (AI) models developed by Anthropic, a startup in which Amazon has invested $8 billion. This information has been disclosed by two individuals who are privy to the matter but have requested anonymity.

The AI startup, Anthropic, was created by former employees of OpenAI. Its Claude large language model is responsible for managing the majority of intricate tasks for Amazon’s new Alexa+. This information was initially reported to CNBC by sources close to the matter.

Amazon’s decision to use Anthropic’s AI models is a significant one, as the company has stated that it is "agnostic" when it comes to choosing the correct model for the job. This means that Amazon does not favor one model over another but chooses the one that is best suited for the task at hand.
