Odyssey Ai-One Mallet Putter

Odyssey borrows some of the variable face thickness ideas generated by artificial intelligence that have fueled the driver designs of parent company Callaway in recent years to reimagine how its putter faces might work. The result is two new putter lines, one featuring an aluminum-backed urethane face insert and the other a milled titanium insert, and each uses a distinct and asymmetrical thickness pattern to create more consistent off-center distance control.

Ai-One ($300) will be available in five options: The #1, Double Wide DB blades, and the Rossie S, #7S (slant neck), and #7CH (crank hosel). Ai-One Milled ($450) will come in eight versions: One T and Two T in blades; Three T, Six T, Seven T DB (double bend shaft), Seven T CH (crank hosel), Eight T and Eleven T in mallets.



Most of us think of the putter face as a study in feel, but the engineers at Odyssey thought, Why can’t we get the face to be active and flexing on putts, too? The key was using artificial intelligence to produce the strangely bumpy back of the face. This insert uses “micro-deflections” to help mis-hits roll nearly as well as center strikes. When it comes to feel, is there anything better than fewer three putts?

  • Designers used artificial intelligence to develop a face that produces distance control.
  • Aluminum face insert is layered with the same urethane used for the White Hot insert.
  • Lightweight Stroke Lab steel shaft features 20-gram counterweight in the grip to control stroke tempo.
  • Nine models across four head styles (2-Ball, Jailbird Mini, Rossie, Seven); double bend, crank hosel and slant neck options; head weight: 360 grams; lengths: 33-35 inches; loft: 3 degrees
