Amazon Web Services’ annual tech conference AWS re:Invent has wrapped. And the singular message, amid a deluge of product news and keynotes, was AI for the enterprise. This year it was all about upgrades that give customers greater control to customize AI agents, including one that AWS claims can learn from you and then work independently for days. Amazon CTO Dr. Werner Vogels capped off the final night with a keynote aimed at lifting up developers and assuaging any fears that AI is coming for engineering jobs. AWS re:Invent 2025, which runs through December 5, started with a keynote from AWS CEO Matt Garman, who leaned into the idea that AI agents can unlock the “true value” of AI. “AI assistants are starting to give way to AI agents that can perform tasks and automate on your behalf,” he said during the December 2 keynote. “This is where we’re starting to see material business returns from your AI investments.” On December 3, the conference pressed on with its AI agents messaging, as well as deeper dives into customer stories. Swami Sivasubramanian, vice president of Agentic AI at AWS, gave one of the keynote talks. To say he was bullish is perhaps understating the vibe. “We are living in times of great change,” Sivasubramanian said during the talk. “For the first time in history, we can describe what we want to accomplish in natural language, and agents generate the plan. They write the code, call the necessary tools, and execute the complete solution. Agents give you the freedom to build without limits, accelerating how quickly you can go from idea to impact in a big way.” While AI agent news promises to be a persistent presence throughout AWS re:Invent 2025, there were other announcements, too. Here is a roundup of the ones that got our attention. TechCrunch will update this article, with the newest insights at the top, through the end of AWS re:Invent. Be sure to check back. Werner out … Amazon CTO Werner Vogels had the closing keynote of the conference — and it looks like this will be his last one. Techcrunch event San Francisco | October 13-15, 2026 “This is my final re:Invent keynote,” he said, then quickly added he is not leaving the company. “I’m not leaving Amazon or anything like that, but I think that after 14 re:Invents you guys are owed young, fresh, new voices.” Vogels then spent more than an hour talking to a packed room before ending with a “Werner, out” and a literal mic drop. Will AI take your job? Vogels spent much of the closing keynote talking about AI and its role in the future, including the looming threat that it will take away jobs. “Will AI take my job? Maybe,” Vogels asked and answered, before noting that some tasks will be automated, and some skills will become obsolete. “So maybe we should rephrase and reframe this question. Will AI make me obsolete? Absolutely not, if you evolve.” Next-gen CPU AWS unveiled its Graviton5 CPU on Thursday, the next-generation chip that the company promises will be its highest performing, most efficient yet. The Graviton5 contains 192 processor cores, a dense and efficient design that AWS says reduces the distance data must travel between cores. That helps cut inter-core communication latency by up to 33% while increasing bandwidth, the company said. Doubling down on LLMs AWS announced more tools for enterprise customers to create their own models. Specifically, AWS said it is adding new capabilities for both Amazon Bedrock and Amazon SageMaker AI to make building custom LLMs easier. For instance, AWS is bringing serverless model customization to SageMaker, which allows developers to start building a model without needing to think about compute resources or infrastructure. The serverless model customization can be accessed through either a self-guided path or by prompting an AI agent.AWS also announced Reinforcement Fine Tuning in Bedrock, which allows developers to choose a preset workflow or reward system and have Bedrock run their customization process automatically from start to finish. Amazon CEO Andy Jassy took to social media platform X to expound on AWS chief Matt Garman’s keynote speech. The message: The current generation of its Nvidia-competitor AI chip Trainium2 is already bringing in loads of cash. His comments were tied to the reveal of its next-generation chip, Trainium3, and meant to forecast a promising revenue future for the product. Database savings arrives Tucked among the dozens of announcements is one item that is already getting cheers: Discounts. Specifically, AWS said it was launching Database Savings Plans, which help customers reduce database costs by up to 35% when they commit to a consistent amount of usage ($/hour) over a one-year term. The company said the savings will automatically apply each hour to eligible usage across supported database services, and any additional usage beyond the commitment is billed at
