LiveBench Code Completion: leaderboard

LiveBench's code completion task gives a programming problem plus the first part of a correct solution and asks the model to write the rest. The joined program must pass every test for the problem to score. It began with LeetCode problems, but since the April 2025 release the questions center on real-world libraries; the board is percent of items passed, higher is better.
