America is not short of open models so much as the institutions with an incentive to build them, and the American open-source coalition is mobilized yet unled. Token volume is moving toward specialized, constrained models, and post-training them has become a first-class discipline with a real market and no way to measure superiority. Meanwhile, the builders doing the actual work have never had a stage.
In the SI League, builders compete in four weight classes to build the best open models under strict constraints. The argument every competition makes is that what a model is made from, and who made it, matters more than how large it is.
Divisional fights run quarterly. The divisions are as follows: Featherweight, <8B parameters; Lightweight, 8-20B; Middleweight, 20-70B; and Heavyweight, >70B. Champions hold belts and defend them. Alongside the divisions, the league runs one-off competitions with unique formats and constraints, some designed with and commissioned by the companies who care about the task at hand.
Competitors enter alone or as teams. Fights are announced in advance and judged on the night. Winning models are released under the SI label, credited to the builder.
Scoring is run by an independent evaluation partner. Fights are scored on coding tasks written fresh for each fight, sealed until submissions lock, and published in full afterward. Sponsors buy affiliation with the league, its competitions, and its teams. They never buy anything to do with the outcome. There are no exceptions.
The league exists to find superior ingredients, the label exists to ship them, and the competitions exist to witness the finding. This is where the good stuff is proven.
Keep intelligence open. Keep it fighting. 🇺🇸
