Much ado about hallucinations: a brief assessment of the judicial response to large language model (LLM) hallucinations in the United States and Canada.

The surge in the utilization of generative artificial intelligence within the legal profession, particularly in preparing legal documents, has prompted a flurry of responses from the judiciary, including practice directives and standing orders.
