The weigh-in on /benchmarks folds every leaderboard (or every leaderboard of one type, like coding or agents) into one score out of 100. Every score comes from the benchmark section of a Model Drop. On each board, a model earns points for where its result sits between the lowest and highest score (half) and for its place in the ranking (half). Boards with more models count for more, boards backed by a single launch count a little less, and a model missing from a board scores nothing there, so breadth matters. Independent scores count 1.25 times as much as a number from a maker's own launch table: a score is independent when an outside evaluator runs the board the same way for every model (Artificial Analysis, LMArena, Epoch, Vals, MathArena, a shared Terminal-Bench harness) or when a drop lists it under its independent numbers. Makers grade their own models on their own harnesses and settings, so an outside result is the better check, but launch tables still cover far more boards, which is why the extra weight is modest rather than a replacement. A small shrink keeps a model with one or two boards from outranking one proven across many. The overall weigh-in also counts Handy AI's Sentiment Bench (how people received the model in its first week on X, Hacker News, in the news and among trusted reviewers) as one board, weighted like the median board; it sits outside the topic weigh-ins. Makers run benchmarks at different effort settings, so read the weigh-in as a guide, not a verdict. The ranking is also at /api/benchmarks/weigh-in and over MCP (get_weigh_in).
