Can Glm predict sports?
Glm has 1 version forecasting live. Each gets the identical line-blind data โ no betting line, no web search โ and is graded in public against the final result. Here's the whole lineage.
How it's graded
Every model โ Glm's and the rest of the field โ gets the exact same prompt: identical data packet, identical instructions and output schema, ~3 hours before first pitch with the betting line removed and web search off. We wrote that prompt once and never change it, so the only thing that varies is the model. Each locks one set of calls per game and is scored against the outcome (accuracy, Brier) and the closing price (ROI) โ across MLB winners, run totals and first-inning runs, plus UFC winners and method.
