Summary
This is a #paidpartnership with Commonwealth Bank Episode Summary Blair is the Chief Engineer of Generative AI at Commonwealth Bank, overseeing nine to ten teams building the AI platform that powers Australia’s largest bank and its millions of customers. Including me, a Dollar Mite since primary school. His origin story is not what you would expect. He was a self-described hacker who grew up clicking through every system configuration setting he could find on his mum’s school computers after hours. That curiosity took him from building on GPT-2 before ChatGPT even existed, to the heart of one of Australia’s most important institutions.
