On Monday morning, Nvidia stock dove 11 percent amid worries over the rise of Chinese AI company DeepSeek , whose R1 reasoning model stunned industry observers last week by challenging American AI supremacy with a low-cost, freely available AI model, and whose AI assistant app jumped to the top of the iPhone App Store's "Free Apps" category over the weekend, overtaking ChatGPT.

What’s the big deal about DeepSeek?

The drama started around January 20 when Chinese AI startup DeepSeek announced R1 , a new simulated reasoning (SR) model that it claimed could match OpenAI's o1 in reasoning benchmarks. Like o1, R1 is trained to work through a simulated chain of thought process before providing an answer, which can potentially improve the accuracy or usefulness of the AI models' outputs for some types of questions posed by the user.

That first part wasn't too surprising since other AI companies like Google are hot on the heels of OpenAI with their own simulated reasoning models. In addition, OpenAI itself has announced an upcoming SR model (dubbed "o3") that can surpass o1 in performance.

If one were to observe that I have written critically about Blue Origin over the last half-decade, they would not be wrong.

The reality is that the space company founded by Jeff Bezos has underperformed. Its chief executive for most of this time, Bob Smith, was poorly regarded by his employees. He brought the worst of "old space" tendencies to Blue Origin from Honeywell. And under Smith's leadership, Blue was litigious, slow, and unproductive.

Frankly, it was a bad look for Bezos. He was pumping something on the order of $2 billion a year into Blue Origin for what, exactly? Lawsuits against NASA? Jokes about BE-4 rocket engine delays?

Jeep provided a night in a hotel so Ars could attend the Wagoneer S first drive. Ars does not accept paid editorial content.

This year marks the return of the Jeep Wagoneer, which formerly served as a more luxurious version of the Cherokee, but now hits the market as Jeep's first full EV. The challenge? How to merge the modern electric lifestyle with the outdoorsy, rugged ethos that defines Jeep as a brand, alongside the more recent addition of the internal-combustion Grand Wagoneer SUV's enormous luxury.

First of all, the new Wagoneer S wound up much smaller in person than I expected. The overall profile falls more in line with the shape of mid-size electric crossovers including the Kia EV6 , Hyundai Ioniq 5 , Chevrolet Equinox , and of course, Tesla's Model Y. But the interior volume belies that relatively compact exterior, with plenty of space for me at 6'1" (185 cm) to sit comfortably in both the front and rear seats. Total cargo volumes of 30.6 cubic feet (866 L) with the second row up and 61 cubic feet (1,727 L) with the second row folded flat end up mattering less than the large floor footprint, because the height used to calculate those measurements drops with the low sloping roofline and rear window.

Much of the interior space can be attributed to packaging of the Wagoneer EV's battery. Rather than going for all-out kilowatt-hours in a dedicated skateboard layout, Jeep instead used the Stellantis group's STLA Large platform, in this case stuffed with a 100.5-kWh lithium ion pack built on 400 V architecture. That's enough for an EPA-estimated 303 miles of range (487 km), a solid figure but not a seriously impressive efficiency stat. In comparison, the world-beating Lucid Air Pure RWD manages about 40 percent more range per kilowatt-hour and a Polestar 3 AWD does about 18 percent worse. Claimed DC fast charge times of 23 minutes for a 20-80 percent top up, or 100 miles (160 km) in 10 minutes similarly get the job done without standing out from the pack.
