MaxxBench: Models Clustered at 74% on DeepSWE End Up 23 Points Apart After Tiny Tweaks

A repost surfaces MaxxBench, a new benchmark of 89 DeepSWE tasks with small changes to instructions or starting code — same engineering problem, slightly different requirement.

Models clustered around 74% on DeepSWE end up 23 percentage points apart on MaxxBench, raising the question: good at coding, or good at DeepSWE?
