Amazon Brings Project Rainier Online & Unveils AI-Powered Alexa+ Echo Devices

At the end of September, Amazon hosted its fall 2025 hardware event in which it revealed a series of upgraded products designed around the Alexa+ (pronounced Alexa Plus).

This included four new Echo devices that were purpose-built for Alexa+—Echo Dot Max, Echo Studio, Echo Show 8, and Echo Show 11—which Amazon said were the most advanced Echo devices ever built.

All four devices were customized and purpose-built for the all-new Alexa+.

At the time, the company said all the new Echo devices were available for pre-order, but the Echo Dot Max and Echo Studio would ship on October 29, and the new Echo Show 8 and Echo Show 11 would ship on November 12.

Sticking to that plan, Amazon has now announced that the Echo Dot Max and Echo Studio are available for purchase.

The new devices come with two custom-made chips—AZ3 and AZ3 Pro—and the new AI Accelerator to run AI edge models of the future. It also allows them to deliver more processing power, memory, edge-based computing, advanced sensing capabilities, and AI experiences through Alexa+.

Amazon notes that millions of customers with Early Access to Alexa+ are talking to it over 2x more, having deeper conversations and completing tasks such as controlling smart home devices, booking reservations, and helping navigate the family calendar.

Alexa+ can be used to gather information and complete actions such as entertainment, home organization, shopping essentials, health & wellness, and more.

By improving Alexa’s ability to detect the wake-word by over 50%, filtering out background noise, and infusing Amazon’s best microphone array yet, the new devices allow users to enjoy more natural, free-flowing interactions.

Furthermore, Amazon’s proprietary sensor platform, Omnisense, uses a range of sensors and signals—a 13-megapixel camera, audio, ultrasound, Wi-Fi radar, accelerometer, and Wi-Fi CSI—to act on various events happening in and around a user’s home, bringing more personalized, proactive, and helpful experiences.

Amazon is also launching a new Alexa+ Store, where users can access tens of thousands of devices and services from brands such as TaskRabbit, Fandango, Priceline, Uber, Lyft, Thumbtack, GrubHub, and Yahoo Sports, as well as manage new or existing Amazon subscriptions, including Amazon Music, Amazon Kids+, Alexa Emergency Assist, and more.

Even companies such as Bose, Sonos, LG, Samsung, and BMW will be adding Alexa+ to their speakers, TVs and In-Car experiences.

The other two new Echo devices—Echo Show 8 and Echo Show 11—will be available on November 12.


Amazon also announced that Project Rainier, which is one of the world's largest AI compute clusters, was brought online and is fully operational.

Amazon completed this project within a year of it first being announced, which comes as a major milestone in AWS's commitment to advancing its AI infrastructure.

Project Rainier, which was built in collaboration with Anthropic, features nearly half a million Trainium2 chips and is expected to sport more than 1 million Trainium2 chips by the end of the year.

Trainium2 chips are custom-designed AI chips built specifically to train AI systems and are unlike general-purpose chips available in laptops or phones. As per Amazon, a single chip is capable of completing trillions of calculations a second. In comparison, “it would take one person more than 31,700 years to count to one trillion.”

The current compute capacity is over 5x what Anthropic used to train its previous AI models, and Anthropic is already actively using Project Rainier to build and deploy future models of its renowned Claude AI system.

The project is a cluster that encompasses multiple data centers spread across the United States and is designed as a massive “EC2 UltraCluster of Trainium2 UltraServers.”

“Project Rainier is one of AWS’s most ambitious undertakings to date,” said Ron Diamant, an AWS distinguished engineer and head architect of Trainium. “It’s a massive, one-of-its-kind infrastructure project that will usher in the next generation of artificial intelligence models.”

Do you think Amazon’s ambitious Project Rainier will help it lead the AI infrastructure race and develop the most powerful AI models, inspiring other companies to follow suit?
