Reproducibility Study of Large Language Model Bayesian Optimization

arXiv — cs.CLTuesday, November 25, 2025 at 5:00:00 AM
  • A reproducibility study revisits the LLAMBO framework, a prompting-based Bayesian optimization method utilizing large language models (LLMs) for optimization tasks. The study replicates core experiments from Daxberger et al. (2024) using the Llama 3.1 70B model instead of GPT-3.5, confirming LLAMBO's effectiveness in improving early regret behavior and reducing variance in results.
  • This development is significant as it validates the LLAMBO framework's claims, demonstrating that contextual warm starting through textual descriptions enhances performance in Bayesian optimization tasks, which can lead to more efficient machine learning processes.
  • The findings highlight ongoing challenges in the field of LLMs, particularly regarding their predictive accuracy and calibration. While LLAMBO shows promise, it also raises questions about the limitations of LLMs as discriminative surrogates compared to traditional methods, reflecting a broader discourse on the reliability and application of AI in various domains.
