Problem

The group, with about 5,000 employees, wanted to raise productivity in everyday office work such as drafting, research and coding.

Approach

A new AI business reform support department built Buddy on GPT-4 through Microsoft Azure OpenAI Service and ran it inside the company's closed network, so staff could enter internal information. It does not learn from user inputs. It came in web, chat and spreadsheet versions and handled Q&A, slide outlines, idea generation and code. It went to all group employees on 30 November 2023, with rules to verify answers and label AI-generated content.

Results

about 500,000 hours per yearexpected working hours saved, the company's projection based on about 100 hours for each of about 5,000 employeesCompany's own claim[1]

Takeaway

The company set out its use rules and security setup at launch. The savings figure was an assumption of 100 hours per employee, not a measurement.
