I think as well there might be "algorithms" that can work with local LLMs. With local LLMs there is a small context window, but not that much cost per token. So perhaps there is a way to do lots of small prompts that work in a sequence to produce a result.

Like perhaps you could produce 5 versions of a piece of code, and then compare them to choose the best.

Also if the local LLMs can call tools, maybe you can use static analysis tools to catch errors and try again in a loop or process of some sort.

There also might be certain languages that work better because those languages have better static checks.
