Downloadable with a datasheet, but the only license statement the project makes about the corpus is a bare "cc" naming no variant, and CC-BY and CC-BY-NC sit two tiers apart. No variant is stated anywhere the project publishes: not in the card front matter, the Hub API, the sibling code_generation and test_generation corpora, the repository LICENSE (MIT, which covers the lcb_runner harness rather than the problems), the README, ERRATA.md, the project site, the leaderboard or the paper. Files that download freely without a grant to use them are not open, and not closed either, so this sits at gated - the barrier is the missing permission rather than a login. The problems are collected from LeetCode, AtCoder and Codeforces, which is a plausible reason no variant has been committed to.

  `license:cc` in the repo tags with no variant; the embedded repo state reads `"gated":false`, so the parquet downloads freely; the README/datasheet still renders the release_v1..v5 change log; 93,572 downloads in the trailing 30 days

  YAML metadata license: cc

• https://huggingface.co/datasets/livecodebench/code_generation_lite/raw/main/README.md recorded 2026-08-13

  card front matter is `license: cc` with tags, pretty_name and size_categories, and nothing naming a Creative Commons variant; the body is a change log of release_v1..v5, a dataset description and usage instructions

• https://huggingface.co/api/datasets/livecodebench/code_generation_lite recorded 2026-08-13

  cardData.license is the string "cc" and the repository tags carry `license:cc`; the sibling corpora code_generation and test_generation carry the same bare `cc`, and execution carries no license at all. The open discussions on the repo are about loading, parquet conversion and version sizes - none asks or answers what the CC variant is
