Amazon is bringing the new AI-powered Alexa Plus to a wide range of its existing Echo devices — but the upgrade will skip many of the earliest models. The majority of the company’s first-generation Echos won’t get support, according to the Alexa Plus FAQ page, though Amazon says they will continue to work with the standard Alexa.

Alexa Plus is here but it's only supported by four Echo products as of now, and won't be supported by more than half a dozen Echo devices.
