MUFG aims to become AI-native with OpenAI
To advance that vision, MUFG is working with OpenAI to roll out ChatGPT Enterprise across Mitsubishi UFJ Bank and create new AI-powered customer experiences. Beginning in 2026, Mitsubishi UFJ Bank began a phased rollout of ChatGPT Enterprise so that approximately 35,000 employees could use it in their daily work, as MUFG continues its journey toward becoming an AI-native company. ## Building an AI-native foundation with OpenAI MUFG is building the systems, environments, and culture that make AI part of everyday work.

Why it matters
Support is repetitive and time-sensitive. Agents can draft answers, look things up and handle simple requests, so people can focus on the tricky ones. It is one of 554 sightings filed under Customer Support on Agent Sightings (number 515 by interest), and one of 145 involving ChatGPT.
How you could try it
Here is a reusable prompt, written by us in our own words, that captures the task. Paste it into ChatGPT or any similar agent and adjust the details to your situation.
I want an agent to handle routine customer questions end to end, and pass anything unclear to a person. The tool in the source case was ChatGPT.
Tip: Start small: run it once on a low-stakes example, read what the agent did, and only then let it run on real work.
