Ask HN: I had Codex and GPT 5.6 Sol running for 12 days, 870k+ LOC. Now what?

A developer reports running OpenAI's Codex and GPT 5.6 Sol Ultra for nearly 13 days, consuming 502,122,866 tokens and generating over 870,000 lines of code for a SaaS extension, and is now unsure how to proceed with review and testing. The developer, who previously shipped features of 50-60k LOC, has found only cosmetic issues so far and is considering writing documentation before launching to production. The post asks whether this scale exceeds human review capability and seeks advice on next steps.

For the last 2 weeks I have been running Codex + GPT 5.6 Sol Ultra non-stop for almost 13 days, working on a huge extension to my SaaS product / business. It used 502,122,866 tokens and created over 870k new LOC. I have done AI coding of huge features in the range of 50-60k LOC before, which were massive already, we managed to ship them and actually deliver value. I know this sounds borderline ridiculous, but this time I don't know what to do. What are the next steps here? It is obviously impossible to review, but it is almost as impossible to actually test. I had put A LOT of work into planning and the workflows and features were spec'ed very precisely and with lots of care and analysis. So far I have only found cosmetic issues, the entire core of the application seems to be working just fine. I have thought about starting with a user manual / knowledge base for it, to capture the features and have plenty of documentation. But then what? Launch it to production? Have I passed the threshold of what is humanly possible to do with AI coding, or is there any hope?
