> If you know what you need and can clearly articulate it well enough, there really is no limit to what you can build with proper instructions, provided the solution is in its training data and you have a good enough BS detector.

In other words: you must already know how to do what you are asking the LLM to do.

In other words: it may make sense if typing speed is your bottleneck and you are dealing with repetitive tasks that have well been solved many times (i.e., you want an advanced autocomplete).

This basically makes it useless for me. Typing speed is not a bottleneck, I automate or abstract away repetition, and I seek novel tasks that have not yet been well solved—or I just reuse those existing solutions (maybe even contributing to respective OSS projects).

The cases where something new is needed in areas that I don’t know well it completely failed me. NB: I never actually used it myself, I only gave into a suggestion by a friend (whom LLM reportedly helps) to use his LLM wrangling skills in a thorny case.

Those that will benefit the most will be senior developers. They might not know the exact problem or language, but they should know enough to guide the LLM.

I definitely use a LLM as a typist and I love it. I've come to a point now where I mentally ask myself, "Will it take more time to do it myself or to explain it?" Another factor is cost, as you can rack up a bill pretty quickly with Claude Sonnet if you ask it to generate a lot of code.

But honestly, what I love about integrating LLM into my workflow is, I'm better able to capture and summarize my thought process. I've also found LLMs can better articulate my thoughts most of the time. If you know how to prompt a LLM, it almost feels like you are working with a knowledgeable colleague.

LLMs are definitely not for everyone, but I personally cannot see myself coding without LLMs now. Just asking for variable name suggestions is pretty useful. Or describing something vague and having it properly articulate my thoughts is amazing. I think we like to believe what we do is rather unique, but I think a lot of things that we need to do have already been done. Whether it is in the training data is another thing, though.

I was in this exact situation. I worked with an unfamiliar area with a hardware SDK in C that I needed to rewrite for my runtime, or at least call its C functions from my runtime, or at least understand how the poorly written (but working) example SDK invocation works in C by commenting it. The LLMs failed to help with any of that, they produced code that was 1) incorrect (literally doing the opposite of what’s expected) and 2) full of obvious comments and missing implementetions (like “cleanup if needed” comment in the empty deinit function).

Later it turned out there is actually an SDK for my runtime, I just failed to find it at first, so the code the LLM could use or tell me about actually existed (just not very easy to find).

Those were two top LLMs as of December 2024. It left me unimpressed.

I don’t think I would be compelled to guide them, once I understood how the code works it is faster to just write it or read relevant reference.

My friend, who volunteered to waste those precious tokens to help with my project, does use chatbots a lot while coding, but he’s more of an intermediate than senior developer.

> Just asking for variable name suggestions is pretty useful.

I can’t see myself asking anyone, much less an LLM, for the name of a variable. I am known to ask about and/or look up, say, subject domain terminology that I then use when naming things, but to name things well you first need to have a full picture of what you are making. Our job is to have one…
