Artificial intelligence in 2025 was much less about flashy demos and extra about onerous questions. What really works? What breaks in surprising methods? And what are the environmental and financial prices of scaling these techniques additional?
It was a 12 months during which generative AI slipped from novelty into routine use. Many individuals bought accustomed to utilizing AI instruments on the job, getting their solutions from AI search, and confiding in chatbots, for higher or for worse. It was a 12 months during which the tech giants overrated their AI agents, and most people appeared typically bored with utilizing them. AI slop additionally grew to become inconceivable to disregard—it was even Merriam-Webster’s word of the year.
All through all of it, IEEE Spectrum’s AI protection centered on separating sign from noise. Listed here are the tales that finest captured the place the sector stands now.

AI coding assistants have moved from novelty to on a regular basis infrastructure—however not all instruments are equally succesful or reliable. This practical guide by Spectrum contributing editor Matthew S. Smith evaluates as we speak’s main AI coding techniques, analyzing the place they meaningfully increase productiveness and the place they nonetheless fall quick. The result’s a clear-eyed take a look at which instruments are value adopting now, and which stay higher suited to experimentation.

As AI’s energy demands elevate issues, water use has emerged as a quieter however equally urgent situation. This article explains how data centers devour water for cooling, why the impacts fluctuate dramatically by area, and what engineers and policymakers can do to cut back the pressure. Written by the AI sustainability scholar Shaolei Ren and Microsoft sustainability lead Amy Luers, the article grounds a loud public debate in knowledge, context, and engineering actuality.

When AI techniques fail, they don’t fail like folks do. This essay, by legendary cybersecurity guru Bruce Schneier and his frequent collaborator Nathan E. Sanders, explores how machine errors differ in construction, scale, and predictability from human errors. Understanding these variations, the researchers argue, is important for constructing AI techniques that may be responsibly deployed in the true world.

On this insider account, John Dean, the cofounder and CEO of WindBorne Systems, tells readers how his workforce constructed one of the crucial technically formidable AI forecasting techniques so far. The corporate’s method combines autonomous, long-duration climate balloons that surf the wind with a proprietary AI mannequin referred to as WeatherMesh, which each sends the balloons high-level directions on the place to go subsequent and analyzes the atmospheric knowledge they acquire.
WindBorne’s platform can produce high-resolution predictions sooner, utilizing far much less compute, and with higher accuracy than typical physics-based strategies. Within the article, Dean walks readers by the engineering trade-offs, design selections, and real-world checks that formed the system from idea to deployment.

This elegantly written article is my private favourite from 2025. In it, Spectrum freelancer Matthew Hutson tackles one of the crucial consequential and contentious questions in AI as we speak: easy methods to outline artificial general intelligence (AGI) and measure progress towards that elusive objective. Drawing on historic context, present debates about benchmarks, and insights from main researchers, Hutson reveals why conventional checks fall quick and why creating significant benchmarks for AGI is so fraught. Alongside the way in which, he explores the deep conceptual challenges of evaluating machine and human intelligence.

Annually, I roll up my sleeves as Spectrum’s AI editor and undergo the sprawling Stanford AI Index to floor the information that basically issues for understanding AI’s progress and pitfalls. 2025’s visual roundup distills a 400-plus-page report right into a dozen charts that illuminate key tendencies in AI economics, vitality use, geopolitical competitors, and public attitudes.
