This document summarises the key findings and insights from the NeurIPS 2023 Large Language Model (LLM) Efficiency Fine-tuning Competition. The competition aimed to democratise access to state-of-the-art LLMs by challenging participants to fine-tune a pre-trained model within a tight 24-hour timeframe on a single GPU. The analysis of the competition reveals a significant trend towards benchmark overfitting, highlighting the limitations of current evaluation methods. Notably, top-performing submissions prioritised data curation and the use of standard open-source libraries over custom model architectures. The competition also underscored the importance of software quality and reproducibility in the machine learning community. The organisers have released all competition entries and evaluation infrastructure to facilitate further research in this area.
