AI models flub these intelligence tests. Can you fare any better?
Puzzles and games have always been central to AI development. The term “machine learning” was popularized in a 1959 article about an algorithm that learned to play checkers. Chess and Go are famous AI test beds too.
Judged purely on its puzzling skills, AI is improving a lot—and quickly. In late 2024, even the best models could figure out only 18% of the infamous New York Times Connections puzzles; by early 2025, some could solve them nearly perfectly every time.
But puzzles do more than highlight AI’s progress. Seeing where models succeed and fail, and where humans still beat them, offers a window into the technology’s strengths and weaknesses.
We’ve gathered seven puzzles that have stumped models at one time or another—now it’s your turn to see how you fare. Take our test to find out whether you can outsmart AI.

How AI plotted an interstellar journey to Alpha Centauri
A nonprofit organization called the Fermi Explorer Mission announced yesterday that it intends to launch a spacecraft to our nearest star system by the end of 2029.
It’s a hugely ambitious mission—if all goes well, the spacecraft could take up to 80,000 years to arrive at Alpha Centauri, which is 4.4 light-years away. To get there, it will follow a novel trajectory discovered by an AI system developed by PSI, a physics research lab.
Explore how AI found a new route to Alpha Centauri—and what the mission could tell us about alien life.

MIT Technology Review Narrated: the role of the astronaut is in flux
We go to space for geopolitical prestige, manifest destiny, spiritual fulfillment, scientific curiosity, and, increasingly, business opportunities. In the wake of Artemis II, a slew of new books suggest that these justifications are subsumed by one unifying fact: humans have itchy feet, and we are simply wired to roam.
In The Ultraview Effect, space anthropologist Deana L. Weibel frames human space exploration as part of our need to embark on pilgrimages. In A Heart for Space, civilian astronaut Eiman Jahangir recounts one such voyage with Blue Origin. And in Dinner with an Astronaut, former NASA astronaut Leroy Chiao argues that people simply “need to know what’s on the other side.”
“We go into space because we want to explore,” says. “We want to see what it’s like to walk on another world.” But as our presence in space expands, we are bound to bring along the same human foibles that have stymied us on Earth.

Namibia wants to build the world’s first hydrogen economy
Namibia has immense untapped potential for wind and solar power, which could make it possible to produce hydrogen and its derivative products as cheaply as anywhere else. The country hopes to turn that potential into a new engine of national development.
Since 2021, when the government identified hydrogen as a potentially “transformative strategic industry,” it’s become something of a national obsession. There are at least nine projects planned or under construction. One, in Namibia’s south, is among the largest proposed green hydrogen investments in the world.
If even a fraction of this production comes to pass, it will give Namibia’s economy a major boost. But it is a gamble. Green hydrogen technology is still in its infancy, and long-term demand for its products remains uncertain.
Can the country turn its hydrogen ambitions into national development?
