DeepSWE: A Contamination-Resistant Coding Benchmark — James Shi, Datacurve
DeepSWE is a novel benchmark for evaluating AI models on software engineering tasks. It features 113 original, long-horizon problems from real open-source repositories, designed to resist contamination and provide clearer differentiation between models. The benchmark highlights unique failure modes and strengths of models like Claude and GPT, emphasizes realistic prompt design, and uses program-based verifiers focusing on observable behavior.
