IBM’s Watson supercomputer beats humans in Jeopardy

By Aemon Malone Published January 13, 2011

Its may only have been a practice match, but Watson has proven to be a serious competitor to the likes of Jennings and Rutter. Watson is IBM’s Jeopardy-playing supercomputer. And Ken Jennings and Brad Rutter — both Jeopardy champions — served as human competition today during a preliminary Jeopardy match with the machine.

IBM took four years to develop the supercomputer so that it would be capable of mastering the subtleties of the language-based trivia that defines Jeopardy. To get Watson at the Jeopardy-smart level, engineers scanned over 200 million pages of information into its memory.

Watson, named after IBM founder Thomas J. Watson, is made up of 10 racks of IBM Power 750 servers and runs Linux as its operating system. It also has 15 terabytes of RAM, and 2,880 processor cores. That makes Watson able to scan the millions of pages of data stored in its memory in a quick three seconds. Oh, and it won’t fit on a desktop — it’s the size of 10 refrigerators.

Watson is considered to be the next big step forward in artificial intelligence that could soon be applied to areas outside of games. Watson’s creators suggest the machine’s abilities may be useful in the health care industry in the future. In 1997, IBM supercomputer Deep Blue defeated Gary Kasparov in a chess match that ignited the public’s fascination in human-computer competition.

Despite some categories that seemingly only a human could comprehend (“Chicks Dig Me” for one), Watson triumphed in today’s practice round, but not by enough to signal an imminent Watson is ready to lead machines in a world-takeover. Watson finished with a score of $4,400 and Jennings came in second place with $3,400 and Rutter was last with $1,200.

Today’s practice round held in Yorkston Heights, New York set the stage for a series of Jeopardy matches with Watson to be held in February.

What’s the Right Laptop for a Student on a $1,000 Budget?

The best college laptop isn't the one with the longest spec sheet. It's the one that fits your budget and the way you'll actually use it.

Dell XPS 14 Review: Sticker

Buying a laptop for college isn't a decision made in isolation. Tuition, textbooks, housing, meal plans, transportation, and course materials all compete for the same budget, leaving most families with one question before the semester begins: how much is enough to spend on a laptop without paying for features that may never get used?

Siri is about to hear everything you say, but Apple’s privacy approach has me cautiously on board

Apple's new Audio Intelligence features want to hear almost everything you say. A privacy document released alongside them explains why I am mostly okay with that.

Apple Watch Audio Intelligence features

Apple used its September 2026 launch event to enter a feature category it has mostly avoided until now: ambient listening. Siri Recap, Live Rewind, Music Recognition with Shazam, and Sound Recognition all landed on the Apple Watch Series 12 and Apple Watch Ultra 4. All four depend on the watch microphone picking up sound around you far more often than any previous Apple product has.

Siri Recap listens for conversations throughout your day and turns them into short AI summaries you can check later. Live Rewind is smaller in scope but arguably more useful day-to-day. It transcribes the last 15 seconds of whatever was just said with a double-press of the crown. This is perfect for catching a name, a book title, or directions you missed the first time. Music Recognition uses Shazam to identify songs playing nearby without you lifting a finger, much like Now Playing on Google's Pixel devices. Sound Recognition is a useful accessibility feature that listens for sirens, doorbells, and alarms to alert users who have a hearing impairment.

Can You Turn a Mini PC Into a Local AI Agent?

Not every AI task needs the scale of the cloud. An employee searching company documents, a retail kiosk answering product questions, or a digital sign reacting to customer behavior all need fast responses, but they don't necessarily need to send every prompt to a remote data center. Running those workloads locally reduces latency, keeps sensitive information closer to where it's generated, and can lower the ongoing cost of AI deployments. As a result, many organizations are moving toward hybrid AI architectures that handle routine requests on-device while reserving cloud models for tasks that genuinely need more processing power.
