> propose, implement, measure, keep the wins Pretty much what I did to let Codex with gpt5.4xhigh improve my fairly complex CUDA kernel which resulted in 20x throughput improvement.

Concretely, what interesting changes did it make to achieve such a significant improvement?

A lot of it was beyond me, but this was all the branch names for all the stuff it tried, most of it unsuccessful of course. About 10x perf improvement came from architectural changes, and then 2x from micro optimizations.

Kudos to that, I guess? Gowin FPGAs hav…

Wtf, this has a name now? I thought of this exact idea literally months ago but never had the time to do any experiments on it. At the time I dismissed it as potentially being incredibly expensive for the improvement you do get, and runs into typical pitfalls of evolutionary algorithms (in the same way evolution doesn't let an organism grow a wheel, your LLM evolution algorithm will never come up with something that…

This is not a new idea at all, many many have had it, no one really can claim it

Genetic algorithms have existed since the 60s / 70s, e.g. computers learning to play a game. LLMs aren’t particularly guide at it. I think hyperparameter tuning may actually be a kind of genetic algorithm.

Hyperparameter tuning could be done by genetic algorithm. I think it’s a bit of a category error to say that it is a genetic algorithm though.

Hyperparam tuning is usually done by Bayesian Optimization though.

Has anyone actually written a verifier for a business / project?

Its tangential, but: I’m currently doing a rewrite of the backend of a project, and the verifier is basically the instruction of “maintain v1 functionality if observed from the api side externally”. This allows making a lot of tests based on existing data in the system and how the frontend expects data.

> "If you can write the rules down, an agent will satisfy them faster than your team will." a fantastic opportunity to become the next next big thing and write a verifier verifier. at the hypothesized inflexion point where AI instantly performs exactly as commanded, what happens to heavily regulated industries like medical? do we get huge leaps and bounds everywhere EXCEPT where it matters, or is regulation going to…

I'm medical-adjacent. We're still bottlenecked on human review and ops. Not because of regulation, we just don't trust the inputs or the outputs enough yet. But also, a lot of the things we'd want an agent to be have access to we don't trust humans with, either, often for stupid historical reasons.

Yeah that’s correct, it could use it, but there are better alternatives for this particular problem.
