I was one of the first to touch the OAI code model. Me and Albert developed the in-the-wild testing harness still in use today. We pulled all nighters to get GitHub approved for participation in the MSFT-OpenAI deal using those test results.
Existing Microsoft AI teams worked to halt our work, pushing their own small, worse models instead of OpenAI's.
I protoyped and lobbied for creation of the VScode extension. I invented and hacked the ghost text prototype into VScode, I invented the block based termination and implemented all the tree-sitter based logic needed to do it. Then I had to lobby up to Satya to get VScode to implement proper support in less than 6 months.
I named it Copilot.
I implemented GH auth, made the waitlist and onboarding. Helped design the e2e http/2 go server, after designing the fast.ly based precursor. Coordinated moving from OpenAI datacenter to Azure to improve Asia experience, and oversaw the cutover.
I was Chief Architect. It was my baby. Sad if this is how they are spinning the story internally at GitHub today.
