Ken1.0-67B is a specialized large language model (67 billion parameters) engineered for the Russian legal domain. Unlike general-purpose models, Ken1.0 was finetuned on a massive proprietary dataset containing over 30 million legal documents, including the Civil, Criminal, and Labor Codes of the Russian Federation, as well as extensive court practice records.
This model is designed to bridge the gap between generic AI and professional legal expertise.
