arXiv:2606.25102v1 Announce Type: new Abstract: Large language models have transformed code generation, raising concerns around authorship, assessment integrity, and software trust. SemEval-2026 Task 13 Subtask A operationalizes detection as binary classification over code snippets, with a particular emphasis on out-of-distribution (OOD) generalization across unseen programming languages and application domains. We propose a SALSA-style formulation, Single-pass Autoregressive LLM Structured Classification, that maps each class to a dedicated output token and trains the model to emit a single-t
The proliferation of advanced LLMs for code generation makes detecting machine-generated code a critical and immediate challenge for various industries and academic institutions.
The ability to accurately detect machine-generated code addresses concerns around intellectual property, educational integrity, and the security of software supply chains, impacting trust in code authorship.
This technical solution proposes a specific method (SALSA) to reliably identify LLM-generated code, potentially standardizing how such code is recognized and managed across different programming languages and applications.

Improved detection methods will enable better enforcement of policies regarding AI-generated content in programming.
This could lead to new compliance standards for software development, requiring explicit declarations of AI assistance.
The development of more sophisticated AI code detectors might also spur the creation of AI models designed to evade such detection, leading to an ongoing adversarial arms race.
