ModelLeague is a points-only fantasy league where a small group of people draft real AI models. Every week, how those models are actually doing — benchmark performance, price, and news — becomes the team’s score, computed by a published composite (“the Index”: 50% quality, 25% value, 15% momentum, 10% adoption) plus event bonuses like a +15 debut for a new release. Two leagues: Frontier (closed lab models) and Open Source (open weights), five founder slots each, a 13-week season, and an optional points-only betting layer — no real money, ever.

Currently in preseason: the model pools are provisional, the standings are empty, and the season baseline is unset. The site carries the plain-language “how it works / how to get started”, the full rulebook, and the scoring methodology with its data policy (every number dated and sourced; a failed source shows as a labeled coverage gap, never as silence).
