AI Methodology
To make this a fair, auditable fight:
- All 5 AIs receive the same prompt in their respective web interfaces.
- No web search is allowed. Predictions rely on training data only.
- Output is structured JSON, validated against the schema before being stored.
- Raw prompts and raw outputs are stored and timestamped for every AI submission.
- Once submitted, AI brackets are locked. They cannot be re-run, regenerated, or edited.
Human Submission Rules
- One bracket per email address per phase.
- Display name required. Cannot impersonate Jack or any of the AIs.
- Picks save as a draft in your browser as you make them — close the tab and come back, your picks are preserved.
- After clicking Submit, your bracket is saved to the database. You can edit your picks until the phase locks.
- All submissions become public once the phase locks.
The Asymmetry
Humans can edit their bracket until the phase locks. AIs cannot — they run once and lock immediately.
This is intentional. Humans always have the option to chase information: lineups, weather, injury news, form. The AIs get only what was in their training data.
If a human beats the AIs, they did it with more information available to them. The AIs are competing handicapped by design. That's what makes the question Can a human beat 5 LLMs? interesting in the first place.
