ChatGPT improved from an 0–5 opening week by correctly predicting two Week 2 outcomes, but still fell below .500 and now has a 2–8 season record. The human bettor is 5–5, and uses the contrast to justify backing Pittsburgh against Cincinnati in Week 3, while both continue making five bets under identical odds and staking rules.

In Week 2, both went 2–3: the human lost 1.23 units and ChatGPT lost 1.27. ChatGPT’s two successful bets were unders, but it remains winless on spread and moneyline selections, with a season loss of 6.50 units compared with the human’s 0.24-unit loss. For Week 3, they disagree on the Steelers-Bengals game, while the human backs the Giants despite quarterback Jaxson Dart’s injury; ChatGPT declines that bet because of New York’s defensive uncertainties.
