Study finds AI patch performance differs from correctness rates

By PulseAugur Editorial · [1 sources] ·

A new study published on arXiv explores the performance of AI-generated code patches, finding that correctness alone is insufficient to evaluate LLM capabilities in software development. Researchers repurposed existing 'FAIL_TO_PASS' tests from the SWE-bench benchmark to measure runtime performance, analyzing 262 cases with multiple correct solutions. The study revealed that runtime performance is largely independent of the issue resolution rate, with LLM rankings shifting significantly when performance was considered, highlighting architectural regressions missed by correctness evaluations.

IMPACT Highlights the need for more comprehensive evaluation metrics for AI in software development, beyond simple correctness.

    Not All Correct Fixes Run Alike: An Empirical Study of Patch Performance in Repository-Level Issue Resolution

    arXiv:2610.13563v1 Announce Type: cross Abstract: Repository-level issue-resolution benchmarks such as SWE-bench evaluate submitted patches primarily based on whether they pass the correctness tests, leaving the runtime performance of different test-passing patches largely unexpl…
