Data Agent Benchmark
Agents answer business questions over data split across several database systems, with duplicated and inconsistent records and key facts buried in text. The 104 queries cover 17 datasets and four database systems, based on a study of companies building data agents in six industries. Scores are pass@1 against known answers.
The leaderboard takes pull-request submissions of whole agent systems, many from companies, and had entries dated 2026-10. About 200 GitHub stars.

In the authors’ words
However, building reliable data agents remains difficult because real enterprise data is fragmented across many heterogeneous database systems, with duplicated and inconsistent data, and key information often buried in unstructured text, requiring agents to go beyond just writing SQL or data science scripts to answer questions. Existing benchmarks tackle only individual pieces of this end-to-end workflow (e.g., text-to-SQL over a single database) and are increasingly saturated and contaminated. We present a new benchmark for LLM agents, the Data Agent Benchmark (DAB), grounded in a study of enterprises building production data agents across six industries. DAB comprises 104 queries across 17 datasets and 4 database management systems. On DAB, the best state-of-the-art agent achieves only 57% pass@1. We analyze agent failure modes and distill takeaways for future data-agent development. Our benchmark and experiment code are published at github.com/ucbepic/DataAgentBench.
Qwen 3.8 Max leads with 99.2% among models released by September 2026
Best score per entry from the benchmark's own leaderboard, read on November 12th, 2026. Where a model ran with several settings or harnesses, we keep its best. Names in gray aren't in our model list: fine-tunes, agent systems, products and older models. They don't count toward leaders.
