A "Factcident" AI Model Accidentally Uncovers Real Historical Events


A recent experiment by a hobbyist developer using an AI model trained on Victorian-era texts has led to an unexpected breakthrough in the field of Artificial Intelligence, revealing real historical events from 1834 London that the developer did not know existed until he conducted his own research.

  • A hobbyist developer, Hayk Grigorian, stumbled upon a real historical event from 1834 London while training an AI model on Victorian-era texts.
  • The project, TimeCapsuleLLM, trained an AI model on texts from 1800-1875 London and surprisingly generated historical references with high accuracy.
  • Grigorian's use of smaller language models and careful selection of high-quality training data led to the unexpected outcome.
  • The model demonstrated contextual understanding, recognizing connections between seemingly disparate pieces of information.
  • The experiment offers a prospect for creating interactive linguistic models that can converse with simulated speakers of extinct vernaculars or languages of the past.



  • A recent experiment by a hobbyist developer, Hayk Grigorian, has led to an unexpected breakthrough in the field of Artificial Intelligence. Using a custom-built AI language model trained on Victorian-era texts, Grigorian's creation stumbled upon real historical events from 1834 London, which the developer did not know existed until he conducted his own research.

    The project, dubbed TimeCapsuleLLM, has been training an AI model on texts from 1800-1875 London. The goal was to capture the authentic voice of Victorian-era English in the AI's outputs. Instead, Grigorian's creation surprised him by generating historical references, including a specific year and figures related to real events that occurred during that time.

    The accuracy of this output is surprising, given the limited data used for training. According to Grigorian, the model was trained on approximately 6.25GB of Victorian-era writing without any explicit teaching or fine-tuning on modern text sources. The development process involved using a custom tokenizer and excluding modern vocabulary from the training dataset.

    This unexpected outcome is not entirely surprising in the realm of AI research. Grigorian's use of smaller language models, such as nanoGPT and Microsoft's Phi 1.5, has shown improvements in historical coherence over previous versions. The development team's careful selection of high-quality training data seems to be an essential factor in achieving this outcome.

    One of the most striking aspects of TimeCapsuleLLM is its ability to recognize connections between seemingly disparate pieces of information. Grigorian's creation has demonstrated a capacity for contextual understanding, much like human language processing. This emergent behavior arises from the model's ability to learn patterns and associations within the training dataset.

    For historians and digital humanities researchers, this experiment offers an exciting prospect: the potential to create interactive linguistic models that can converse with simulated speakers of extinct vernaculars or languages of the past. While the accuracy of these outputs may be limited due to confabulations, they could provide valuable insights into antique syntax and vocabulary in use.

    The development team's openness about their methodology and code has enabled a collaborative environment for researchers to build upon Grigorian's work. Future collaborations involving training models on various cities, such as Chinese, Russian, or Indian cities, may further expand the range of linguistic possibilities.

    In an era dominated by AI confabulations, TimeCapsuleLLM stands out as a refreshing example of how language models can unexpectedly reveal real historical events. The incident has shed light on the importance of careful training data selection and the potential benefits of smaller language models for achieving accurate outcomes.
