• Elo still leads overall, but Cortana caught fire in Week 7.
• The two models disagree on just one game this week.

The NFL season is now in Week 8, and the computers are picking their winners for every game.

We took a look at two popular systems used to pick NFL games: Cortana, Microsoft's digital assistant, and Elo, the modeling system used by Nate Silver's FiveThirtyEight.

In both cases, the computers are picking outright winners and not against the spread. However, each gives a likelihood of a team's winning, which, in theory, could help measure the strength of certain lines.

The two models had strong performances in Week 7, especially Cortana, which went 12-3. Elo went 9-6 and still has the lead overall, at 64-42 (60.3%). Cortana is now one game back at 63-43 (59.4%).

Here are the picks for Week 8, with each model's percent chance of winning in parentheses. Games in bold are where the two models disagree on who has the best chance to win. Point spreads are just for reference, via Vegas Insider as of Thursday morning.
