In the same way, you would have a full stack engineer be able to drive a feature from the backend all the way to the front end. So it, it seems like a lot of the work you guys had to do was you as a small team are fully working for a way that the model wants the software to be written. It’s like less human legible for better. Code legibility, agent legibility. How do you think that affects broader teams? So one at OpenAI, do liaison, like this is how software should be written. Like I can imagine, say you join a new team with this methodology, this mindset there’s ways that, teams do code review, teams write code, like teams are structured and a lot of it is for human legibility.
