Who it’s for: The Ai-ONE Square 2 Square putters should appeal to golfers who want to minimize face rotation and increase their consistency on the greens. 

What You Need to Know: This line extension blends a White Hot face insert that was developed using artificial intelligence, with toe-up weighting and balance intended to help golfers reduce face rotation during the stroke. 

The deep dive: Odyssey released the first Ai-One putters in late 2023, promoting them as tools that could enhance a golfer’s distance control thanks to a White Hot face insert engineered with the help of artificial intelligence. The lineup expanded last month to include several new Ai-One and Ai-One Milled putters, including 2-Balls, Jailbirds and other midsize mallets.

Now, Odyssey is introducing the Ai-ONE Square 2 Square line and bringing the AI-designed face insert to a putter category that’s gaining a lot of attention — zero torque putters.

The new Ai-ONE Square 2 Square line includes two mallets, the Jailbird and #7, as well as a heel-toe weighted blade with an extended back flange that is called the Double Wide. All three putters have a center-shafted design, but instead of bringing the shaft into the topline, it connects well behind the face and a few millimeters toward the toe from the center of gravity (CG) location. As a result of that hosel location, if you hold the putters freely across your hands, the toe goes up and the face naturally points forward, toward your target. 

Each Ai-ONE Square 2 Square putter is also designed with a 3.3-degree forward press, so the shaft leans toward your target when you address the ball.  

The combination of the toe-up balance and forward press takes away the putter head’s bias to rotate closed on the backswing and rotate open on the downswing. So, the Ai-ONE Square 2 Square putters remain square to a golfer’s stroke path, regardless of whether that path is relatively straight, slightly arched, or strongly arched.

Odyssey believes this combination of reduced torque (face rotation), the AI-designed White Hot insert, and the latest counterbalanced Stroke Lab shaft can help golfers produce a smoother stroke with a better tempo that naturally keeps the face square to the path, and that should help golfers hit better putts. 

Odyssey is not claiming that this is the first or only zero-torque putter out there, but the Ai-One Square 2 Square putters conquer one of the challenges faced by club designers in this category: zero-torque putters often look very unconventional. The Ai-ONE Square 2 Square putters have classic head shapes that will be familiar to just about every golfer. 

The Jailbird, originally released in 2014 and used by Wyndham Clark to win the 2023 U.S. Open, incorporates Odyssey’s signature Versa alignment stripes. The #7 is a fang-style mallet with dual white alignment lines that help frame the ball, making alignment more intuitive. The Double Wide completes the lineup as a modern, heel-toe weighted blade with a T-shaped white alignment aid.
