as someone who uses ai to help on researching an issue/question - i have no understanding whyvpeople just submit generated code. i realize i just dont use it to generate stuff. i use it to find stuff.
when this forst came out, i thought non devs would use it for creating an app that they use at home just for them. but no, i constantly see people posting about their project and trying to getvpeople involved. a project fully generated by an llm. or as in the issue here, generating code to be merged into a project..why? i jist dont get it.
tatterdemalionI don’t think it’s very hard to understand. It reduces the up-front cost of development.
spartanatreyuTo be more specific, it trades up-front development cost and building competence for knowledge gaps and maintenance hell.
Not always. Prototyping can be valuable in many circumstances when you don’t know the shape you’d like the code to take. Sometimes you need to try something before you know if it’s right. I’d rather throw away prototype code written by an LLM than code I had to write the hard way.
Dave.Ok it occurs to me that people use this like they use a spellinng/grammar checker in a word processor.
Spellcheck:
- They have an idea.
- They type up the idea.
- They run spellcheck and it churns through their document and it fixes mistakes that it can see.
- They send it to someone for review.
LLM coding:
- They have an idea.
- They type up the idea.
- LLM churns on the idea and spits out a solution-of-sorts.
- They send it to someone for review.
Regardless of other opinions of it, they see it as a tool that helps take the effort out of getting ideas into reality.
Edit: Oh wait, this is c/programming. Fuck. Ok, give me 5 minutes for me to sharpen my pitchfork and come up with something that matches the groupthink, I’ll be right back.
You missed the part where they are SUPPOSED to meticulously review the “solution” themselves and have deep foundational understanding of what’s going on to know if it’s a good solution or not.
Ideas are a dime a dozen. It’s not useful when the person lacks the ability to fully vet the solution before passing someone else to review. That just makes them middlemen. When instead the actual maintainer or reviewer could have done the same thing but have that foundational understanding.
Asking LLM to turn “idea” (instead of detailed spec) into a gigantic codebase is like asking your spell checker to write your essays.
Not all of us are doggedly against LLM, it’s just the LLM-haters that are preponderantly loud. They are like the anti-feminists that have to show up in every post about women.
Harassment is not allowed. You may not harass people for using an LLM, regardless of whether or not their use is banned by the policy. You must follow the Code of Conduct at all times when interacting with the Rust project.
Lol, I think that will be as lost on the LLM haters as the contributing policy will be lost on LLM-only users.

Oof, lots of valid points, especially that the value of a contribution is in the decisions it makes. Having an LLM guess those decisions makes the resulting code significantly less valuable.
Hell, one could argue pretty much entirely worthless, because the maintainers could prompt an LLM themselves, if the decisions didn’t matter.
Seems like a good policy in general, open to changes, i hope this will make reviewers’ job easier, considering how hard reviewing PR’s for a university project with partners who insist on using LLMs for almost everything, i can barely imagine how frustrating this all must be.
Saying that “it’s fine” seems a little overly broad, because sometimes it isn’t, but I suppose that by “fine” they simply mean that it’s not forbidden by the policy. A more complete summary would also mention that where it is allowed, disclosure of LLM use is required.
Personally, on the few occasions where I’ve resorted to querying an LLM it’s been very much the same kind of experience that using Stack Overflow used to be. It’s a quick way to see one way that other people have done some thing, but you wouldn’t want to rely on it being the right way.
I guess that the purpose of the one-line summary is to communicate the spirit of the policy. The details that you are asking for, is what constitutes the majority of the the policy document itself. While you could probably summarize the body of the policy in more detail, having multiple lists with different levels of details would likely lead to confusion. So I think that the approach they’ve taken makes sense
As was said elsewhere on the Internet:
Seems pragmatic and well-written. But it doesn’t say “LLM’s are hot garbage in all circumstances and people who use them are all smelly turds,” so I’m guessing there will be backlash in this community.
Hey, I know you are probably trying to help, but when you talk over/about other people and categorize them/put them in boxes, it never helps open opinions and discussions. Maybe don’t put your expectations first, especially if they may be wrong.
Sorry. Thought it’s worth saying, and my hope with this message is to reduce the volume of assumptions people make about each other here.
Fair, but I was making a general comment with tongue firmly in cheek. I didn’t mean to denigrate anybody. Certainly not any individual. It was broad commentary on the general, though certainly not ubiquitous, view on LLM’s in the larger communities on Lemmy.
Hey! I’m a person who specifically wants to hear that LLMs are always flaming garbage. Thanks for the explanation. Intent and tone is hard online. Your original comment, which probably read as a joke and firmly tongue-in-cheek to you, read as a frustrated and resentful snarky one-liner zinger to me until I got this explanation that you didn’t mean it that way. Of course, I’m carrying my own biases (anti-LLM, frustration with harshness and generalizations and insults that I perceive to be happening more frequently on the Fediverse than back on Reddit or in real life).
I wonder if there are more jokesters than actual harsh people and I’m just misinterpreting it. (I have been stepping back from the Fediverse because of how many generalizations and frustrated, resentful, snarky comments I’ve seen; and how many LLM discourse posts I see on programming.dev that I, who have that as a trigger topic, end up rabbitholing down instead of doing something more useful. Me even clicking and commenting on this post is an example of the latter, I fear.)
Thanks again for clarifying your intent and going de-escalation mode, I think we need way more of that energy.
