Twice as fast: Printy Brain v2, our new 3D AI brain

The thing people say most about Printy is what a good job she does, and how fast. Printy Brain v2 is now on for everyone, guests included. A typical reply takes about 25 seconds, down from about 50 on the previous brain. She's twice as fast or more in every group, and the models come out as good as ever. That's twice the rounds in one sitting, so it's easier to end up with a better part.

FIG. 43-A.1 + A.2 — How the two brains compared: the typical reply, and the share of replies that land first time. People new to Printytron were split between them at random, guests among them. Existing accounts ran a smaller test of their own.

The two brains ran side by side, with people new to Printytron split between them at random. In that group, the slowest 1 reply in 10 halved, from about 153 seconds to about 78. More than 97 replies in 100 now land first time. Signed-in accounts can still switch back to the previous brain in BETA OPTIONS.
