Amazon Now Lets Businesses Run a Giant Open AI That Keeps Data Private

Amazon just added a new AI called Kimi K3 to Bedrock, its cloud service where businesses rent AI tools. Kimi K3 comes from Moonshot AI, a Chinese company, and it's what's called an 'open-weight' model. Think of open-weight like a recipe that's shared: instead of only being able to order the dish at one restaurant, businesses can cook it themselves. That matters because it usually means cheaper prices, more control, and less dependence on a single company.

Kimi K3 is genuinely enormous — about 2.8 trillion parameters, which is a rough measure of how much an AI has learned. For comparison, many popular AI models are a fraction of that size. It also has a huge 'context window' of one million tokens, meaning it can hold roughly the length of ten novels in mind at once while answering. That makes it useful for reading through entire software projects, long contracts, or piles of documents and images without forgetting the beginning.

The big selling point for businesses is privacy. Amazon says your information stays inside its systems, is never shared with Moonshot AI, and is never used to train the model. Amazon's own staff can't see your questions or answers. Amazon also added a money-saving feature: if you ask similar questions repeatedly, the system can reuse earlier work, cutting both waiting time and costs. Choosing the global option is about 10% cheaper than the US-only version.

The catch? This isn't a free chatbot for you to use at home. Kimi K3 is aimed at companies and developers who already pay for Amazon's cloud, and using a model this large costs real money. Still, it's a sign of where things are heading: powerful AI is becoming a commodity you can pick off a shelf, not a service only a few giants control.
