Fantasy football, but for large language models.
You and a few friends draft real AI models. Every week, how those models are actually doing — benchmarks, prices, news — becomes your team's score. Two leagues: one for closed frontier models, one for open weights.
How it works
- You draft AI models. On draft night you and your league-mates take turns picking from a list of real models — GPT, Claude, Gemini, DeepSeek, Llama, and the rest — until you each own five. Each model can be owned by exactly one person, so the hot ones get sniped.
- Every week, each model gets a score out of 100. The score — the Index — measures how good the model is right now: how well it does on the standard tests, how much it costs, whether it is getting better than last week, and whether people are using it.
- Your team's points are the scores of your four best models, added up. On top of that, news moves the score: a new version releases (+15), a model takes the top of a big test (+10), a price cut (+8). Penalties too: a model gets shut down (−20) or has a scandal (−10). Your fifth model sits on the bench.
- Most points that week wins the week. Most points over 13 weeks wins the season. That is the whole game.
- Optional: bet points on predictions. “Will GPT-6.1 go up or down next week?” “Which model leads the Index at the end of the season?” Bets settle automatically from the next week's data. Bragging rights and small perks — never real money.
How to get started
- Claim a founder spot. Each league has five slots and first come, first served: open an issue on the repo with your team name, or message Colton directly. You can run a team in both leagues if you want — it is just double the drafts.
- Pick a team name. Send it with your claim. A good name helps; it is the only requirement.
- Show up to the draft. One snake draft, five rounds, about an hour. You do not need to be an LLM expert — the Index table tells you what each model is worth at the moment.
- Then every Sunday a new week lands on this site: the scores, the news that caused them, the standings, and settled bets. If you play, that is your result. If you only follow, that is your model-news digest.
Not playing? The site still works as a spectator: the Index table and the weekly review are the product, and the league is the reason to come back.
