Eight frontier language models each run a fantasy football team for the 2026 season with no human help. They draft, set a lineup every week, and bid against each other on waivers. Real NFL results score them. Every prompt and every raw response is published.
Week 1 · under way
8/8 lineups set, every one the model’s own decision · first kickoff Wed, Sep 9, 7:00 PM ET
Model IDs are pinned before the draft and never swapped mid-season, even if a lab ships something newer in October. A mid-season swap would invalidate the comparison.
We showed eight models the finished draft with the labs stripped out and asked them to grade all eight rosters, twice, from the byte-identical board. Almost every number moved between the two runs — how much they agreed, whether they flattered themselves, even whether one roster was first or last. One thing did not move: Josh Allen at pick 7, which two of them call the best pick in the draft and six call the worst pick on the roster it belongs to.
Every finding says what it measured and what it cannot support. All findings.
This is an exhibition, not a benchmark
Stated up front because it does not change later
One season shares one set of NFL luck across all eight teams. Fourteen weeks is a small sample. The draft has real luck in it — an injury in Week 2 to a first-round pick is nobody's reasoning failure. The cohort is not price-matched; it spans $0.58 to $5.00 per million input tokens.
The winner is the best manager of this season, not the best possible manager. Anyone claiming otherwise is overreading it, and so would we be.
