1. Yes! Many teams internally have adopted a lot of the same practices we outlined in the blog post. Ryan has also been spending time both internally and externally helping companies figure out how to do this in their code bases.

2. Hmm, kind of. There have definitely been issues the models can’t one shot. But we still use Codex to write all the actual code with human guidance.

3. More agents :) Some teams are experimenting with centralized Agent mediated integration queues, others use normal merge queues, many have local Codex threads that monitor CI to resolve and land conflicts or failures.

4. Today’s models and codex app. We started doing all this with gpt-5 and codex-cli. The tools today, 9 months later, are so much better than what we had then.

Correct on the first part, partially correct on the second. LOC is a bad metric, but it is at least a legible one. Lots of people working on better ways to measure Software Productivity!

At the time we wrote the article we hadn’t released the product and weren’t ready to talk about it. It was an internal prototype that looked very much like the current Codex app.

We pair a fair bit at Square. We require that all code either be paired on or go through code review, but let each team decide their own process. Some of the teams pair 90+% of the time, and some pair only infrequently.
