The Globe and Mail reports in its Monday edition that OpenAI released ChatGPT one year ago, kicking off a boom in generative artificial intelligence. Since then, the advances have come at a furious pace. The Globe's Joe Castaldo writes that large language models, which underlie chatbots, can now be used to analyze data, create charts and graphs, interpret photographs, and converse in real time with audio features. At least one fundamental flaw remains: Large language models make stuff up. These errors have become known as "hallucinations," although confabulations is a more appropriate word. The possibility of mistakes is an obstacle for deploying LLMs, especially in settings where accuracy is crucial, such as health care, finance, law and education. Telus is taking a measured approach to generative AI, in part because of the possibility of hallucinations. In April, the telco formed a generative AI board that includes chief executive officer Darren Entwistle to guide the company's approach and later created a data-secure environment for employees to experiment with the technology. Telus has been testing a chatbot to help customer service agents field questions. The bot does not directly interact with customers yet.
