Reflections on the Reproducibility of Commercial LLM Performance in Empirical Software Engineering Studies

Large Language Models (LLMs) have garnered immense interest and funding, yet their non-deterministic nature and rapid evolution pose significant challenges to the reproducibility of empirical software engineering studies. This analysis investigates the current state of reproducibility and the factors that impede it, offering crucial insights for the future of AI research and implementation.

RQ1: Reproducibility Rate
RQ2: Impeding Factors
RQ3: ACM Badges
7.7% Studies fit for reproduction

Our analysis of 65 LLM-centric empirical studies using OpenAI services found that only 5 were even fit for an attempt at reproduction (7.7%). Of these 5, none could be fully reproduced, and only 2 were partially reproducible. This highlights a critical challenge for the reliability and scientific value of current research in this rapidly evolving field.

The challenges to reproducibility stem from both general software engineering research issues and LLM-specific factors. Common problems include missing or incomplete artifacts, unspecified dependency versions, and the use of deprecated commercial LLMs. Many studies also lack crucial details about model configurations like temperature and prompt engineering.

Factor Overall Challenges (86 Articles) Reproduction Challenges (18 Attempted Articles)
Missing/Incomplete Artefacts
  • 35 articles with missing code/data
  • 15 articles with incomplete artefacts
  • 6 articles with incomplete artefacts
Model & Config Issues
  • 8 articles did not state models
  • 57 articles did not report temperature
  • 72 articles did not report top-p/top-k
  • 64 articles did not handle context window size
  • 5 articles used deprecated models
  • 10 articles missing minor model versions
  • 3 articles missing temperature config
  • 10 articles missing top-p/top-k config
Technical/Documentation Issues
  • 50 articles lacked prompt details
  • 6 articles had dependency version issues
  • 5 articles had general code issues
  • 4 articles had incomplete documentation
  • 2 articles were non-executable
  • 2 articles lacked error handling
  • 1 article had deprecated external API

ACM Badge Reliability Under Scrutiny

Our findings reveal that ACM artefact badges, intended to signal the reliability and reusability of research artifacts, are not a reliable indicator for LLM-centric studies. Specifically, half of the 'Artifacts Evaluated - Reusable v1.1' badges awarded for ICSE and ASE 2024 papers did not meet ACM's own requirements just one year later. Issues included incomplete or non-functional artifacts and insufficient documentation. This underscores a need for stricter, more standardized evaluation processes and potentially longer-term validity checks for artifacts in fast-evolving fields like LLM research.

Your AI Implementation Roadmap

A strategic approach to integrating AI, ensuring reproducibility and long-term value in your enterprise.

Reproducibility Audit & Gap Analysis

Assess existing LLM-centric projects for reproducibility, identify missing artifacts, documentation gaps, and dependency issues. Develop a clear plan for standardizing research practices. (3-5 weeks)

Standardized Artifact Development

Implement robust artifact development guidelines, including comprehensive code, data, model versions, and detailed prompt engineering. Utilize containerization for platform independence. (6-8 weeks)

Robust Study Design & Validation

Adopt study designs that account for LLM non-determinism, define clear evaluation metrics, and incorporate independent replication checks. Integrate Bayesian bootstrapping for uncertainty quantification. (8-12 weeks)

Continuous Monitoring & Adaptation

Establish processes for tracking model updates, managing deprecated APIs, and adapting research methodologies to the evolving LLM landscape. Ensure long-term accessibility and reusability of all research outputs. (Ongoing)
