Business Insider profiles VISA executive Rajat Taneja, who is putting GPT-4 – the engine that powers Windows Copilot – into the hands of every employee:

The company has licensed a private version of GPT-4 that runs on Microsoft Azure and incorporates Visa’s internal data. The payments company has opened the tool to 13,000 employees since February with guidelines on using it and the underlying data. It aims to roll it out to the rest of its workforce by year-end.

Taneja himself used it recently to revamp a job posting for an AI role, using ChatGPT to rewrite the job description, draft interview questions based on the position, and then ask the AI for the ideal answers.

Visa continues to experiment with similar AI models, like Meta’s AI model Llama 2 and those from French-American company Hugging Face, Taneja said.

Visa’s engineers are leveraging AI to write code, and while it’s not perfect, more AI-generated code is being used each week, with about half of the code being approved in some cases. The idea is that engineers will direct and supervise models and use them as an “assistant coder,” somebody who never forgets anything, who is trained on the latest technologies, and who continues to know more every single day, Taneja said.

Not only will AI change how Visa employees work, but it’ll push the firm to grow its headcount too. There are more than 2,500 technologists who build Visa’s data and AI platforms and services, but the firm will look to hire 2,000 more people in the next few years to carry out its AI road map.
