LakeQA: leaderboard

LakeQA (2026) tests LLM agents on exploratory multi-hop question answering over a data lake of about 40 million Data.gov and Wikipedia documents, where the agent must search, download and query the relevant files before answering. The board is exact match in percent on the 1,007 LakeQA-full tasks; higher is better.
