Ask HN: How can LLMs boost my developer experience?

As in the title. But let me elaborate a few constraints:

- I work in a secretive industry (finance) so no web-based service touching my code is allowed

- It is also very correctness-obsessed, so LLM-generated code in general would be hard to sell

But then, it feels like there must be more I can do to try and be more productive. I occasionally use ChatGPT to find tool incantations, and that's great. But that's like a better Google/StackOverflow. What am I missing? Some local LLMs for formatting or refactoring? Documentation-writing? Design questions? Etc.

Any brave souls feel strong enough to ELI5 what they actually do, for money, with coding and LLMs? Whenever I google it, there's a chorus of comments on Reddit saying how useless AI coding tools are...

My personal experience, fwiw, is that LLM generated code needs iterations of prompts and manual fixing, which in the end takes about as long as doing the damn thing by hand in the first place. Except for trivial and boring stuff, which they are good at, but which doesn't come along that often. But again, would be awesome to know what I am missing out on.

Informed stories of LLM failures also welcome!
