A new research paper proposes a diagnostic framework to understand how large language models (LLMs) process historical languages, decomposing the difficulty into tokenization cost, predictive uncertainty, semantic robustness, and context sensitivity. The study evaluated this framework on 17th-century Italian, 19th-century Italian, and 18th-century Russian texts. Findings indicate that while historical texts impose an encoding tax, LLMs can still represent historical meaning, and a simple temporal context prompt can significantly reduce historical surprisal.
