Does anyone have good estimates of what percent of real production code is currently being written by LLMs? (& presumably this is rather different for your typical SaaS backend vs. frontend vs. device drivers vs. kernel schedulers...)

View on HN

By all companies? I'd say less than 10% of all LOC today are generated by LLMs.

Really? In my bubble of internet news it seems the sheer number of companies that have formed and shipped LLM code to production has already surpassed existing companies. I've personally shipped dozens of (mediocre) human months or years worth of code to "production", almost certainly more than I've ever done for companies I've worked at (to be fair I've been a lot more on the SRE side for a few years now).

Depends on your reference class. There's a lot of companies and teams where it's literally 100%, and I would be surprised if there were any top company where it's below 75%. I wouldn't be terribly surprised if the industry-wide percentage were a lot lower, although I also have no idea how you'd measure that.

I would be surprised if there were any top company where it's above 5%.

The slop Claude generates isn't going anywhere near production without being edited by hand.

Perhaps it depends on what you mean by "edited by hand"? It's definitely still common for human beings to review generated code and tell Claude "no you need to do it this way". But most developers at Google, Meta, etc. no longer open up an IDE and type in code themselves.

I don't give a bleep what the bleeps at Google and Meta are doing. (Judging by the quality of ""software"" they put out - probably nothing all day.)

In reality it's extremely rare that AI generated code isn't combed through line-by-line and refactored.

(For real software, that is, not VC scams like OpenClaw or litellm or whatever.)
