Large language models have become increasingly utilized in programming contexts. However, due to the recent emergence of this trend, some aspects have been overlooked. We propose a research approach that investigates the inner mechanics of transformer networks, on a neuron, layer, and output representation level, to understand whether \textbf{there is a theoretical limitation that prevents large language models from performing optimally in a multilingual setting.} We propose to approach the investigation into the theoretical limitations, by addressing open problems in machine learning for the software engineering community. This will contribute to a greater understanding of large language models for programming-related tasks, making the findings more approachable to practitioners, and simply their implementation in future models.
