LongHorizon Full Data-Agent Benchmarks
Companion data artifacts for five complete evaluation tracks:
- DataSciBench full55 / 167 metric entries
- DABStep full450
- DABStep-Research full100
- DSBench Modeling full74
- LongDS full68 / 2,225 turns
The companion GitHub repository contains processed manifests, evaluation code,
historical API ReAct baseline code, download/preparation tools, and the frozen
source lock. artifact_manifest.json records every uploaded object's size,
SHA-256, installation path, and archive contents.
DataSciBench runtime trees and DSBench extracted directories are intentionally not duplicated here. They are reconstructed from the compact source artifacts. DABStep leaderboard submission history is excluded; all 450 task definitions and all seven context files are included. LongDS is split by dataset family so downloads can resume without a monolithic 19 GB archive.
The DABStep project metric uses six official public-dev references and 444 DataCOPE Genesis proxy references. It is not an official hidden-leaderboard full-test score.
