LangSelect optimizes LLM code generation by routing to cost-effective languages

Researchers have developed LangSelect, a novel system designed to optimize Large Language Model (LLM) code generation by intelligently routing requests to the most cost-effective target programming language. This approach acknowledges that for certain tasks, multiple programming languages can satisfy the same test cases, and the choice of language can significantly impact the generated code's length and, consequently, its cost. LangSelect aims to improve efficiency by selecting a target language, and if the initial attempt fails, it falls back to another option. Evaluations on the MultiLang-Bench corpus demonstrated that LangSelect can reduce token usage by over 50% while maintaining a high pass rate, showcasing its potential to define a practical cost-correctness frontier for verifiable code generation.

IMPACT This research could lead to more cost-efficient LLM code generation by optimizing language selection.

    LangSelect: Cost-Aware Target-Language Routing for LLM Code Generation

    arXiv:2609.18959v1 Announce Type: new Abstract: LLM code-generation systems usually choose a target programming language before decoding and treat that choice as fixed. We show that, for language-flexible programming tasks -- tasks where several target languages are acceptable an…
