🏆 Leaderboard •
LiveCodeBench is a "live" updating benchmark for holistically evaluating code related capabilities of LLMs.
Particularly, it evaluates LLMs across a range of capabilties including code generation, self-repair, test output prediction, and code execution.
This is the code generation scenario of LiveCodeBench. It is also… See the full description on the dataset page: https://huggingface.co/datasets/livecodebench/code_generation.livecodebench-code_generation_liteimpossible_livecodebenchlivecodebench_code_generation_lite_parquet

LiveCodeBench-CPP: An Extension of LiveCodeBench for Contamination Free Evaluation in C++
Overview
LiveCodeBench-CPP includes 454 problems from the release_v6 of LiveCodeBench, covering the period from October 2024 to May 2025. These problems are sourced from AtCoder (287 problems) and LeetCode (167 problems).
AtCoder Problems: These require generated solutions to read inputs from standard input (stdin) and write outputs to standard output (stdout). For unit testing, the… See the full description on the dataset page: https://huggingface.co/datasets/nvidia/LiveCodeBench-CPP.execution

LiveCodeBench-v6-Plus
A curated coding benchmark of 91 problems selected by hardness/discrimination
(lcb-v6-plus). It combines two sources, all in one clean schema:
64 evolved problems — mutated/evolved variants from LiveCodeBench-v6
(each carries its seed_problem).
27 original problems — un-evolved AtCoder problems taken directly from
livecodebench/code_generation_lite
release v6 (seed_problem is null).

Ko-LiveCodeBench
This dataset is the livecodebench/code_generation_lite dataset with the question_content field translated to Korean.
Dataset Versions
The dataset provides multiple configurations (subsets) corresponding to different release versions:
release_v1: Problems released between May 2023 and Mar 2024 (400 problems)
release_v2: Problems released between May 2023 and May 2024 (511 problems)
release_v3: Problems released between May 2023 and Jul 2024 (612 problems)… See the full description on the dataset page: https://huggingface.co/datasets/bzantium/ko-livecodebench.Ag-LiveCodeBench-XThis repository contains the multi-PL variant of LiveCodeBench, prepared in the Agnostics project.
