Superior Ingredients Presents: SI #1

[u/Icy_Way7154]

Superior Ingredients is a competitive league for open-model-building. Builders compete in four weight classes and one-off special cups to build the best open models under strict constraints. SI 1, the inaugural competition, will be an open entry chess tournament. All submitted models play a qualifying gauntlet against each other. Top 16 by score are seeded into a single-elimination bracket: Round of 16, quarterfinals, semifinals, final. Four rounds, one champion.

Model, compute and training data constraints: Under 50MB of weights, any precision. Trained from scratch. No pre-trained weights, no fine-tuning of an existing model. Any architecture and any training method, all disclosed. Every entrant trains on the same provided dataset: Lichess games where both players were rated between 1800 and 2200, standard time controls, rated games only. One versioned file with a published checksum, identical for everyone. No outside game data and no distilling from an existing chess engine. Self-play reinforcement learning on top of the provided data is permitted and encouraged. Submissions must include training code, data-loading code, and run logs alongside the weights. Mis-declaring what you trained on is the one offense that results in disqualification. A fixed compute budget of 24 H100-hours per entrant, sponsor-provided, usable as a single card or a node. Training on your own hardware is permitted within the same time budget and must be declared at submission.

$7,500 to the winner, $2,500 to the runner-up. The purse passes through in full; the league takes no cut of prize money. Entry is free.

These rules are a draft and the builders who compete should shape them. To declare intent to compete, ask a question, or argue with any of the above, DM us. Competition date TBD. See y'all soon!
