PwC is leveraging OpenAI’s GPT-4 language model to develop and embed generative AI into its own technology stack and client-services platforms. The goal is to help other companies use generative AI, while building the tools to do so. The model is trained on massive stores of language data to understand natural-language prompts and produce intelligible responses. Once the models are fully trained and tested, they can be used to quickly write reports and prepare compliance documents, analyze and evaluate business strategies, identify inefficiencies in operations or create marketing materials and sales campaigns. Microsoft’s Azure cloud-computing service is providing the added compliance and data security for PwC to access OpenAI’s generative AI tools.
