We evaluated Rubber Duck on SWE-Bench Pro, a benchmark of large, difficult, real-world coding problems drawn from open-source repositories. Here’s what we found: Claude Sonnet 4.6 paired with Rubber Duck running GPT-5.4 achieved a resolution rate approaching Claude Opus 4.6 running alone, closing 74.7% of the performance gap between Sonnet and Opus. We noticed that Rubber Duck tends to help more with difficult problems, ones that span 3+ files and would normally take 70+ steps.
