New research tackles AI code generation evaluation and testing

Two new research papers explore advancements in evaluating AI-generated code. The first, TENET, introduces a framework for repository-level code generation using test-driven development, achieving high Pass@1 scores on benchmarks like RepoCod and RepoEval with Claude Sonnet 4. The second paper, ACES, proposes a novel method for assessing the reliability of tests used to evaluate code generation, focusing on consistency and the ability of tests to distinguish correct from incorrect code. AI

IMPACT These papers introduce novel approaches to improve the reliability and effectiveness of evaluating AI-generated code, potentially leading to more robust code generation models.

    Embarrassingly Simple Self-Distillation Improves Code Generation

    Can a large language model (LLM) improve at code generation using only its own raw outputs, without a verifier, a teacher model, or reinforcement learning? We answer in the affirmative with simple self-distillation (SSD): sample solutions from the model with certain temperature a…

    TENET: One Step Toward Test-Driven Development for Repository-Level Code Generation

    arXiv:2509.24148v3 Announce Type: replace-cross Abstract: Test-Driven Development (TDD) is a widely adopted practice that requires developers to create and execute tests alongside implementation. With recent advances in Large Language Models (LLMs), developers can shift from manu…

    ACES: Who Tests the Tests? Leave-One-Out AUC Consistency for Code Generation

    arXiv:2604.03922v2 Announce Type: replace Abstract: Selecting LLM-generated code candidates using LLM-generated tests is challenging because the tests themselves may be incorrect. Existing methods either treat all tests equally or rely on ad-hoc heuristics to filter unreliable te…
