Cortana likes the Bears at home versus the Cardinals. Getty Images Microsoft's Cortana — the virtual assistant that predicts NFL games — had a killer start to the season, going 13-3 in straight-up picks of all 16 NFL games during Week 1.

There weren't too many upsets around the league, but Cortana nailed probably the biggest by correctly picking the Rams over the Seahawks.

Both results from Monday night may have surprised some, as the Falcons beat the Eagles and the 49ers topped the Vikings, but Cortana correctly picked both by sticking with the home teams. Its three misses were the Texans, the Colts, and the Bucs. (For what it's worth, Nate Silver's ELO model went 12-4, so it was a good week for algorithms across the board.)

Here are Cortana's Week 2 picks, as of Wednesday morning. Vegas favorites (with point spreads) are in parentheses. We'll update these throughout the week if they change, and look out for our official picks later in the week!

Cortana and Vegas are in strong agreement this week, with the two most notable exceptions being Cortana liking the Bears over the Cardinals and the Bills over the Patriots. Cortana also prefers Johnny Football to Marcus Mariota, unlike Vegas. As usual, the disagreements between Cortana and Vegas are games to circle on your calendar.
