It also enhances Alexa’s ability to process nuance and ambiguity-much like a person would-and intelligently take action. This new Alexa LLM will be connected to hundreds of thousands of real-world devices and services via APIs. To be truly useful, Alexa has to be able to take action in the real world, which has been one of the unsolved challenges with LLMs-how to integrate APIs at scale and reliably invoke them to take the right actions. If you want to know more, you can follow-up. When you ask for the latest on a trending news story, you get a succinct response with only the most relevant information. We’ve also focused on reducing latency so conversations flow naturally, without pause, and responses are the right length for voice-not the equivalent of listening to paragraph after paragraph read aloud. To enable that with Alexa, we fused the input from the sensors in an Echo-the camera, voice input, its ability to detect presence-with AI models that can understand those non-verbal cues. In any conversation, we process tons of additional information, such as body language, knowledge of the person you’re talking with, and eye contact. We’ve studied a lot about conversation in the last few years, and we know that being conversational goes beyond words. We believe this will drive the future of Alexa, enabling us to enhance five foundational capabilities: It’s based on a new large language model (LLM) that’s been custom-built and specifically optimized for voice interactions, and the things we know our customers love-getting real-time information, efficient smart home control, and maximizing their home entertainment. This is an early look at a smarter and more conversational Alexa, powered by generative AI. Today, we’re excited to share an early preview of what the future looks like.

A longstanding mission has been to make a conversation with Alexa as natural as talking to another human, and with the rapid development of generative AI, what we imagined is now well within reach. We’ve always thought of Alexa as an evolving service, and we’ve been continuously improving it since the day we introduced it in 2014. Having passed half a billion devices sold, and with tens of millions of interactions every hour, Alexa has become part of the family in millions of households.

What started as a sketch on a whiteboard has evolved into an entirely new computing paradigm-one that has fundamentally changed how people across the world interact with technology in their homes. Ideas that seemed like science fiction not so long ago are now a reality-and there’s no better example of that than Alexa. Over the last few years, we’ve often talked about how we’re living in a golden age of artificial intelligence (AI).
