RealBench is a new repo-level code generation benchmark that adds UML diagrams to natural language specs, showing LLMs struggle more at full repositories, create modules with errors, and perform best with whole-repo generation on small projects versus module-by-module on complex ones.

Bridging Generation and Training: A Systematic Review of Quality Issues in LLMs for Code
A review of 114 studies creates taxonomies for code and data quality issues, formalizes 18 propagation mechanisms from training data defects to LLM-generated code defects, and synthesizes detection and mitigation techniques.

RealBench: A Repo-Level Code Generation Benchmark Aligned with Real-World Software Development Practices
RealBench is a new repo-level code generation benchmark that adds UML diagrams to natural language specs, showing LLMs struggle more at full repositories, create modules with errors, and perform best with whole-repo generation on small projects versus module-by-module on complex ones.
