Not “may be”: just look how swe-bench scores drop to single digits once it in C# https://arxiv.org/html/2506.12286v3
So the "Verified" part of "SWE Bench Verified" means.. not "Verified" at all. I don't get it, who is so opposed to doing the bare minimum of manual work and check what these models are doing? At least back in the day grad students doing an easy meta-paper understood it meant doing some repetitive manual work. Now we got benchmarks by hype vendors who think they can use the thing they are benchmarking to .. mark the b…
Data contamination stemming from the fact that it's based on already-solved problems in public repositories is a different issue that cannot be addressed by verifying the benchmark questions harder, but only by putting stricter limits on the model under test.
