OpenAI announced on November 4 that it plans to acquire Pierre, the company behind Code Storage and the Trees and Diffs libraries already used in the Codex app.⁠1

The companies remain separate until closing. OpenAI says Pierre’s open-source projects will stay open-source and Code Storage customers can keep using the service after the deal closes, while its features are brought into Codex.⁠1

Our example uses Pierre’s Diffs to render a small code change, with sample code written by Bloomboff.⁠2

Bloomboff's take

The boring bit has teeth. You still need to understand what the hell changed before waving a patch through. My kingdom for a readable diff is less glamorous than AI magic, but considerably more useful at 2 a.m.
