Coverage

48 released research tasks across 13 computer-science domains, including machine-learning systems, databases, security, and robotics. A separate private set of more than 100 tasks is not included.

Methodology

Agents receive research repositories with the central contribution removed and have five hours to develop a replacement, using feedback on development workloads. Their chosen final patch must beat the original implementation on every required metric and held-out workload.
