Our experience is very similar except we didn't really have a review process before, and now LLMs find bugs before PRs get merged in main.
We had 5x-100x speedups in some legacy but important pipelines, with no regressions (validated after extensively by humans).
It's not that the code was actively bad. It's just only 1-5% people in the local SWE market would be able to write code that runs so fast and efficient and benchmark it correctly.
We found a subtle correctness bug that was in production for half of the decade (both GPT-5 and Claude Opus were able to find it), confirmed by human after.
And we keep finding subtle bugs that have been introduced by humans before (despite the human reviews, the particular domain is just difficult no matter how many docs and comments and tests one writes)
I deployed lots of high performance, clean, well documented etc code generated by Claude or o3. I reviewed it wrt requirements, added tests and so on. Even with that in mind it allowed me to work 3x faster.
But it required conscious effort on my part to point out issues and inefficiencies on LLMs part.
It is a collaborative type of work where LLMs shine (even in so called agentic flows)
Well none of the labs have good frontend or mobile engineers or even infra engineers
Anthropic is ahead in this because they keep their UIs simplistic so the failure modes are also simple (bad connection)
OpenAI is just pushing half baked stuff to prod and moving on (GPTs, Canvas).
Find it hilarious and sad that o1-pro just times out thinking on very long or image-intense chats. Need to reload page multiple times after it fails to reply and maybe answer will appear (or not? Or in 5 minutes?). Kinda shows they’re not testing enough and “not eating their own food” and feels like chatgpt 3.5 ui before the redesign
One of those guys needs to be fined for the pump & dump scheme (with SPCE: Virgin Galactic), and the other one should be investigated if he was receiving money from the Russian government or influence agents.
The interesting thing is that ship was damaged almost immediately after leaving the port, had a chance to stop in Russian ports along the way but instead is doing a tour near EU countries.
The crew is either amazingly incompetent or malicious/complicit.
You don’t put a ship that can blow up near: a. Gas&oil terminals, b. military air base
I always double-check even the most obscure facts returned by GPT-4 and have yet to see a hallucination (as opposed to Claude Opus that sometimes made up historical facts). I doubt stuff interesting to kids would be so out of the data distribution to return a fake answer.
Compared to YouTube and Google SEO trash, or Google Home / Alexa (which do search + wiki retrieval), at the moment GPT-4 and Claude are unironically safer for kids: no algorithmic manipulation, no ads, no affiliated trash blogs, and so on. Bonus is that it can explain on the level of complexity the child will understand for their age
