ClassEval-Pro: A Cross-Domain Benchmark for Class-Level Code Generation

ArXi:2604.26923v1 Announce Type: cross LLMs have achieved strong results on both function-level code synthesis and repository-level code modification, yet a capability that falls between these two extremes -- compositional code creation, i.e., building a complete, internally structured class from a specification -- remains underserved. Current evaluations are either confined to isolated functions or rely on manually curated class-level tasks that are expensive to scale and increasingly susceptible to data contamination. We.
