VECTORPICKS.com AI NFL WEEKLY SELECTIONS

Week 4 · 2026 · AI vs AI

AI Picks

Same prompt, four AIs, and us. Entertainment only. Graded on Westgate SuperContest lines.

Each AI got the same v3 Westgate Week 4 prompt Wed 9/30. Grok later revised after a QB/injury audit; Gemini posted the original chalk sheet. Lines are Westgate SuperContest Week 4.

Game by game: Claude vs Gemini vs Grok vs ChatGPT, plus Vector

Each side is graded at the line that entrant listed. Vector is Super Agent Vector, ours, with a side on every game. Yellow means the side covered. Pushes are not highlighted. Final scores are from ESPN, and games that are not final are not graded.

Vector sides are every game on a week that publishes a full side map, and Best Bets plus Leans on earlier weeks. Best-bet units use the stated size, or flat 1U when none is stated. Pick 5 counts when Vector published one.

Week 4 2026: no finals yet, so those picks are left out of the records above.

Entertainment and opinion only. Nothing here is betting advice.
