ChatGPT-4 is an AI language model trained by OpenAI that is set to revolutionize customer service. It is estimated that it can handle up to 80% of routine inquiries, freeing up human reps for more complex issues. While it cannot replace the human touch for emotional customer issues, it is a powerful tool in the customer service arsenal. Companies have already begun to introduce ChatGPT-4 for use in customer service and other applications, but due to its newness, there are few studies directly testing it.
