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 won’t support “certain older generation Echo devices,” such as the first-generation Echo, Echo Dot, Echo Plus, Echo Tap, Echo Spot, and Echo Show; the second-generation Echo Show won’t support it, either. Amazon spokesperson Kristy Schmidt confirmed that is the full list of devices. If so, that still leaves many early Echo devices that will work with Alexa Plus.

That means I’ll be able to ask Alexa to book a restaurant reservation through my Echo Flex, the quirky modular Echo speaker that plugs straight into a wall outlet. And people can still get an AI-generated song piped through speakers they’ve connected their microphone-only Echo Inputs to. And if you have an ancient first- or- second-gen Echo Show 15 or newer Echo Hub, those will apparently get access to the AI-enhanced Alexa, too. Schmidt confirmed that each of those will be compatible.

Perhaps it’s a bummer that some of the older Echo devices won’t use AI to book reservations, track ticket prices, or generate fake songs. But at least they’ll still be able to do the old Alexa stuff, like turn on your lights or tell you the weather. And given rumors about the struggle Amazon has had getting Alexa Plus to work right, that might be a good thing, at least for a while.
