A language model called TimeCapsuleLLM has been trained exclusively on data from 1800-1875 to reduce modern bias and emulate the voice, vocabulary, and worldview of that era. The model has been trained on a dataset of 90GB of text from London during that time period. The goal of the project is to create a language model that can reason exclusively using knowledge from that time period. The model has shown promising results, with outputs that reflect the linguistic style and historical context of the time period.
