All the biggest news from AWS’ big tech show re:Invent 2025
Amazon Web Services’ annual technology conference, AWS re:Invent, has completed its first official day of programming and has already delivered an endless stream of product news.
The unsurprising theme is AI for the enterprise, although this year it’s all about upgrades that give customers more control to customize AI agents – including an agent that AWS claims can learn from you and then work independently for days.
AWS re:Invent 2025, which runs through December 5, kicked off with a keynote from AWS CEO Matt Garman, who built on the idea that AI agents can unlock the “real value” of AI.
“AI assistants are starting to make way for AI agents that can perform and automate tasks on your behalf,” he said during the Dec. 2 keynote. “This is where we start to see material business returns from your AI investments.”
While AI agent news promises to be a lasting presence at AWS re:Invent 2025, there were other announcements as well. Here’s a look at the announcements that caught our attention. TechCrunch will continue to update this article until the end of AWS re:Invent, so be sure to check back.
An AI training chip and Nvidia compatibility
AWS introduced a new version of its AI training chip called Trainium3, along with an AI system called UltraServer that runs it. The TL;DR: This upgraded chip comes with some impressive specs, including a promise of up to 4x performance improvements for both AI training and inference, while reducing power consumption by 40%.
AWS also provided a teaser. The company already has Trainium4 in development, which will be able to work with Nvidia’s chips.

Extensive AgentCore capabilities
AWS has announced new features in its AgentCore AI agent building platform. A standout feature is Policy in AgentCore, which makes it easier for developers to set boundaries for AI agents.
AWS also announced that agents can now log and remember things about their users. Additionally, it announced that it will help its customers evaluate agents through 13 pre-built evaluation systems.
A non-stop AI agent worker bee
AWS has announced three new AI agents (there’s that term again) called “Frontier agents,” including one called “Kiro autonomous agent” that writes code and is designed to learn how a team likes to work so it can operate largely independently for hours or days.
Another of these new agents handles security processes such as code reviews, and the third performs DevOps tasks such as preventing incidents when pushing new code live. Preview versions of the agents are now available.
New Nova models and services
AWS is introducing four new AI models within its Nova AI model family – three of which are text generating and one that can create text and images.
The company also announced a new service called Nova Forge, which gives AWS cloud customers access to pre-trained, mid-trained, or post-trained models that they can then supplement by training on their own proprietary data. The big goal of AWS is flexibility and customization.
Lyft’s argument for AI agents
The taxi company was one of many AWS customers performed during the event to share their success stories and evidence of the impact of products on their business. Lyft uses Anthropic’s Claude model through Amazon Bedrock to create an AI agent that handles questions and concerns from drivers and riders.
The company says this AI agent has reduced average resolution time by 87%. Lyft also said it has seen a 70% increase in drivers’ use of its AI agent this year.
An AI factory for the private data center
Amazon also announced “AI Factories” that will allow large companies and governments to run AWS AI systems in their own data centers.
The system was designed in collaboration with Nvidia and includes both Nvidia and AWS technology. While companies using it can equip it with Nvidia GPUs, they can also opt for Amazon’s latest AI chip, the Trainium3. The system is Amazon’s way of addressing data sovereignty, or the need for governments and many companies to control their data and not share it, even using AI.
