Problem

SoftBank had introduced generative AI tools, but some employees still did not use them. Its HR team wanted everyone to gain practical experience before wider use of AI agents.

Approach

In July 2025, SoftBank required employees to create custom GPTs using its enterprise ChatGPT access. It provided introductory materials and seminars for different roles. Employees could make assistants for work or personal interests, and HR said most completed the assignment by the end of August.

Results

100custom GPTs each employee was required to create, according to SoftBank's HR teamCompany's own claim[1]

Takeaway

SoftBank measured initial exposure to AI through participation. Completing the exercise did not establish sustained workplace use or productivity gains.
