Walmart Global Tech Vice President of Emerging Technology Desirée Gosby said the retailer will be using generative artificial intelligence model GPT-4 to provide offerings including "text to shop," Venture Beat reports. Gosby said generative AI will "be as big a shift as mobile, in terms of how our customers are going to expect to interact with us," also noting possibilities like generative AI models that anticipate what customers are looking for. "We focus on building a natural language understanding capability that is retail-specific," Gosby said.
