Commonwealth Bank of Australia, Australia's largest bank, forbids employees to use ChatGPT and adopt their own AI system.

The Commonwealth Bank of Australia, Australia's largest bank, has banned employees from using the popular AI chat robot ChatGPT and has adopted its own AI system internally. Andrew McMullan, chief data and analyst officer of the Commonwealth Bank of Australia, said the bank had revised its group AI policy in the past three months to make it clear that employees could not use ChatGPT on the bank's devices or enter the bank's undisclosed information into external chatbots.
