Code2LoRA: Hypernetwork-Generated Adapters for Code Language Models under Software Evolution
arXiv:2606.06492v1 Announce Type: cross Abstract: Code language models need repository-level context to resolve imports, APIs, and project conventions. Existing methods inject this knowledge as long inputs (retrieved through RAG or dependency analysis) or through per-repository fine-tuning and LoRA -- costly at repository scale and brittle to evolving codebases. We introduce Code2LoRA, a hypernetwork framework that generates repository-specific LoRA adapters, effectively injecting repository knowledge with zero inference-time token overhead. Code2LoRA supports two usage scenarios: Code2LoRA-St
The increasing complexity and scale of codebases, combined with the demand for performant and adaptive code language models, drives innovation in efficient knowledge injection methods.
This breakthrough offers a more efficient and scalable way to adapt code language models to specific repositories, potentially accelerating software development and improving AI-assisted coding at a lower cost.
Code language models can now be updated with repository-specific knowledge without costly fine-tuning or token overhead, leading to more responsive and context-aware AI coding assistants.
