Coding with LLMs (Claude Code, OpenAI Codex) is often presented as the ‘killer app’ for Generative AI. But looking at data, it seems the one piece of the puzzle missing is actual cost. …
Published a library doing some very specific data processing. One of the algorithms I implemented was a bit too slow: it would take about a week to process data. I reckon implementation was a little bit sloppy, but I’ve been implementing a bunch of algorithms from research papers and this was pretty much the published implementation.
I asked Claude to analyse the implementation and check whether it could be improved, half an hour later I got a 26,000% improvement in performance with exactly the same results passing all tests.
Of course, I could have done that myself. But optimization had to go down to simd level; I doubt I would have been able to do that in less than a week of work.
