SWE-InfraBench - Passed Tests Share: leaderboard
Metric: Passed tests share (%): share of all unit tests across the tasks that the generated code passes, so partly correct solutions earn credit; 100 AWS CDK (Python) infrastructure-as-code tasks built from 34 open-source and custom repositories: the model writes a masked code block from a natural-language request inside a real project, and the synthesized CloudFormation template is checked by hidden unit tests; one attempt per task, temperature 0.25, Anthropic models prompted with extra XML tags; higher is better. Source: arxiv.org. Saturation forecast: Estimated already saturated. 20 models tracked.
