Breaking the Language Barrier: CodeMixBench Redefines Multilingual Code Generation

CodeMixBench: Evaluating Large Language Models on Multilingual Code Generation ▲ Visual representation of CodeMixBench’s test dataset structure Why Code-Mixed Code Generation Matters? In Bangalore’s tech parks, developers routinely write comments in Hinglish (Hindi-English mix). In Mexico City, programmers alternate between Spanish and English terms in documentation. This code-mixing phenomenon is ubiquitous in global software development, yet existing benchmarks for Large Language Models (LLMs) overlook this reality. CodeMixBench emerges as the first rigorous framework addressing this gap. Part 1: Code-Mixing – The Overlooked Reality 1.1 Defining Code-Mixing Code-mixing occurs when developers blend multiple languages in code-related text elements: # Validate user …
