Microsoft Cortana had a decent Week 13, correctly predicting 10 of 16 NFL games.

It's now 126-66 (65.6%) on the season.

Cortana is a Windows phone virtual assistant that's using an algorithm from Bing Predicts to pick every game of the NFL season. After making headlines at the World Cup by correctly predicting 15 of the tournament's final 16 games, it's having a harder time picking NFL games.

The algorithm picks games straight up, not against the point spread. Its record is one game better than the Vegas favorites (which are 125-64-3, 65.1%) and a few games worse than Nate Silver's ELO model (which is 132-60, 68.8%).

After getting two out of the three Thanksgiving games wrong, Cortana made a comeback and went 9-4 on Sunday and Monday. Vegas favorites also finished the week 10-6, and ELO went 9-7.

Here are Cortana's picks for Week 14 as of Sunday morning. We'll update them if they change throughout the week (Vegas favorites in parentheses):

Dallas Cowboys vs. Chicago Bears — Cowboys win, 56.5% chance (Cowboys -3.5)

win, 56.5% chance (Cowboys -3.5) Pittsburgh Steelers vs. Cincinnati Bengals — Bengals win, 56.6% chance (Bengals -3)
