Why do you think it's not relevant to the "optimise in a loop" thing? The way I think of it, it's using LLMs "in a loop" to move something from arch A (that costs x$) to arch B (that costs y$), where y is cheaper than x. It's still an autonomous optimisation done by LLMs, no?

Did the LLM suggest moving to the new architecture? If not that’s not what’s under discussion. That’s just following an order to translate.
