Product features of the Ai-ONE putter

• The Ai-ONE putter, now also available as a plug-in model, marks a significant advance in putting through the use of AI. After four years of AI-driven development at Callaway, previously successfully used in drivers, this technology is now transferable to putting.

Loss of ball speed dramatically reduced

• The Ai-ONE putter addresses the problem of velocity loss with off-center impact. Studies show that ball speed drops by up to 20% when the impact point is 1 cm from the core, which can shorten a 10-meter putt by 2 meters. Odyssey has developed an AI design that reduces this loss to approximately 5% (50 cm at 10 meters) using an innovative insert.

The insert

• The Ai-ONE putter's insert consists of an aluminum piece with complex AI-designed bumps and a resin piece on the impact face. Originally, the insert was intended to be made entirely of resin, but the complexity of the shape required combining it with aluminum. This material combination overcame the original durability issues of aluminum and enabled the creation of a product with the same feel and sound as the White Hot insert.

Polycarbonate windows

• Each Ai-ONE putter features a transparent polycarbonate window installed on the back of the blade model and on the sole of the mallet model. This window reveals the complex shape of the AI-designed insert, providing unique technological insight.

Design and weight

• The putter body is made of stainless steel and features a dark blue PVD coating. Screw-in weights of approximately 15 g are installed at the toe and heel of the sole to increase the moment of inertia.

Newly developed steel "STROKE LAB 90 shaft"

• The STROKE LAB 90 shaft, specifically designed for the Ai-ONE putter, is made entirely of steel and weighs approximately 90g. The new shaft reduces torque, prevents unnecessary movement during the stroke, and includes a counterweight on the hand side that increases the putter's moment of inertia.
