This work established new benchmarks for what 'large' meant in LLMs and showed the impact of parameter count on few-shot learning.
- Scaling Laws for Neural Language Models, Jared Kaplan, Sam McCandlish, Tom Henighan, Tom B. Brown, Benjamin Chess, Rewon Child, Scott Gray, Alec Radford, Jeffrey Wu, Dario Amodei, 2020 arXiv preprint arXiv:2001.08361 DOI: 10.48550/arXiv.2001.08361 - This paper systematically investigates how neural language model performance scales with model size (parameters), dataset size, and training compute. It provides theoretical and empirical insights into the relationship between parameter count and model capacity, performance, and resource requirements.
