LiveCodeBench

LiveCodeBench Team
restricted / Overall score: 3.0

Continuously updated coding benchmark that collects fresh problems from LeetCode, Codeforces and AtCoder after a model's training cutoff, so evaluation stays contamination-free. It covers code generation, self-repair, execution and test-output prediction, and ships release-versioned snapshots with hidden test cases bundled.

public problems with hidden test cases bundled

LiveCodeBench's card names only the Creative Commons family, "cc", with no stated variant anywhere the project publishes - the repository, README, site or paper - and its MIT license covers only the lcb_runner harness, not the problem corpus. Files download freely, but without a stated permission to use them, the corpus reads as restricted rather than open.

Adoption

3 medium confidence
3.0

Adoption is measured by Hugging Face downloads of livecodebench/code_generation_lite, the benchmark's only declared distribution artifact.

Capability

not assessed

A dataset is not 'capable', so capability is left unscored. Its contamination resistance - the "live", continuously updated design - is a real quality strength, but openness and adoption are what carry this category.

    The page describes a problem corpus: "Each problem instance consists of a problem description, input/output examples, and hidden test cases", released in versions; nothing on it claims a capability of its own. Searched the body for throughput, accuracy, SOTA and pass@1: none.
