Researcher Builds TimeCapsule LLM With Historical Data

Hayk Grigorian built TimeCapsule LLM, a model trained exclusively on London-published texts from 1800–1875 totaling about 90 GB, to produce historically constrained responses. The model avoids modern knowledge and aims to help historians study period-specific biases and perspectives, though limited surviving documents and dataset composition may affect its representativeness and accuracy.
