Overview

Large language model (LLM) coding agents constantly decide whether a version satisfies a constraint such as ^1.2.3 or =2.0,1.2 means =1.3.0) traps every model on Cargo (near 60%), and although standard PEP 440 prefix matching is universal, on zero-pad/post-release corner cases GPT-5.1 collapses (0/26) while Claude stays at 97-100% (verified on a 67-item oracle-validated set). — SemVerBench: Benchmarking LLM Comprehension of Version-Constraint Resolution Semantics (2026)

We observe that 28 percent of Maven projects exceed 10 times amplification, indicating a systematic pattern rather than isolated outliers, compared to 14 percent for RubyGems, 12 percent for npm, and zero percent for Cargo, PyPI, Packagist, CocoaPods, and Pub. — How Deep Does Your Dependency Tree Go?
