Amazon goes all-in on Gen AI: From shopping to space, a "once-in-a-lifetime reinvention"

Amazon’s latest earnings call made one thing resoundingly clear: generative AI isn’t just a long-term bet—it’s the company’s present and future. Across divisions, Amazon is rapidly deploying AI to rewire everything from customer support to scientific research. According to the company, “Generative AI is going to reinvent virtually every customer experience we know, and enable altogether new ones we’ve only fantasized about.”

So far, early AI use cases have focused on productivity and cost savings like business process automation and multilingual support. But Amazon expects a sweeping transformation across sectors: coding, shopping, primary care, cancer research, biology, space, and financial services, to name just a few.

The timeline? “It won’t all happen in a year or two—but it won’t take ten either.” The pace is faster than almost any prior tech wave.

Inside the Investment Playbook

Why is Amazon investing this heavily and this fast? “If your mission is to make customers’ lives better and easier every day, and you believe every customer experience will be reinvented by AI, you’re going to invest deeply and broadly,” the company spokesperson says.

Over 1,000 generative AI applications are being developed across Amazon’s portfolio, transforming experiences in shopping, personal assistants, video and music streaming, advertising, healthcare, and smart home devices.

AWS, in turn, is laying the groundwork with its own AI building blocks:

Custom silicon chips like Amazon Trainium and Trainium2

Model development and deployment platforms like Amazon SageMaker and Bedrock

Proprietary frontier models via Amazon Nova

New agentic capabilities for task automation

All this requires capital. AI chips are significantly more expensive than CPUs, and demand is surging. Amazon noted that AI revenue is already at a “multi-billion-dollar annual run rate,” growing at triple-digit year-on-year percentages. The infrastructure being built today—from datacenters to chips—will monetize gradually over years, but the company sees it as a foundational investment: “AI is a once-in-a-lifetime reinvention of everything we know.”

Why Is AI So Expensive—and Will That Change? Much of AI’s high cost comes down to chips—and today, most AI workloads rely on a single dominant chipmaker. But Amazon believes that will shift. Its Trainium2 chips already promise 30–40% better price-performance than current GPU-powered instances.

While training models is still costly, inference—the real-time generation of outputs—is poised to dominate future AI spending. That’s because inference happens constantly in large-scale applications. Amazon says it will soon become a core cloud service, just like compute and storage.

To bring costs down further, Amazon is also betting on:

Model distillation

Prompt caching

Optimized computing infrastructure

New model architectures

The company expects these changes will “unleash AI being used as expansively as customers desire”—a flywheel effect where lower unit cost drives greater adoption and total spend, much like what AWS did for cloud computing.

The Alexa+ Bet

What about personal assistants? According to Amazon, no digital assistant until now has truly combined intelligence with the ability to act. Alexa+ is its answer to that gap.

Described as “comparably intelligent to the leading chatbots,” Alexa+ also takes actions: controlling smart homes, making reservations, setting reminders, ordering products, booking tickets, and more. It can transfer media between devices, play your favorite artist, and remember your preferences across Amazon’s ecosystem.

With over 600 million Alexa devices in use, Amazon expects Alexa+ to become even more central in consumers’ lives—marking another front in its AI-first future.
