The core of the story has to be technology focused.


Post guidelines

Title formatPost title should mirror the news source title. If you don't like the title of article, look for an alternative source instead of editorializing it.
URL formatPost URL should be the original link to the article (even if paywalled) and archived copies left in the body. It allows avoiding duplicate posts when cross-posting.
[Opinion] prefixOpinion (op-ed) articles must use [Opinion] prefix before the title. Opinion articles refer to articles that their publisher doesn't explictly endorse.
Country prefixCountry prefix can be added to the title with a separator (|, :, etc.) if the news is from a local publisher who doesn't clearly mention the country.


Rules

1. English onlyTitle and associated content has to be in English.
2. Use original linkPost URL should be the original link to the article (even if paywalled) and archived copies left in the body. It allows avoiding duplicate posts when cross-posting.
3. Respectful communicationAll communication has to be respectful of differing opinions, viewpoints, and experiences.
4. InclusivityEveryone is welcome here regardless of age, body size, visible or invisible disability, ethnicity, sex characteristics, gender identity and expression, education, socio-economic status, nationality, personal appearance, race, caste, color, religion, or sexual identity and orientation.
5. Ad hominem attacksAny kind of personal attacks are expressly forbidden. If you can't argue your position without attacking a person's character, you already lost the argument.
6. Off-topic tangentsStay on topic. Keep it relevant.
7. Instance rules may applyIf something is not covered by community rules, but are against lemmy.zip instance rules, they will be enforced.

Preamble: I am a huge LLM/codegen skeptic, for a litany of reasons.

With that said, this honestly sounds like whoever did the prompting didn’t include something like this in the prompt, along with nuanced adversarial review loops:

unsafe blocks are strongly discouraged, and must be specifically justified, and survive antagonistic review by a rust language specialist agent and software security specialist agent. Part of the intent of this reimplementation is to leverage the strengths of the rust language itself, and rampant unsafe usage directly contradicts that.

"It can't be that stupid, you must be prompting it wrong."

The ol' reliable.

No, I’m saying that there are ways to introduce feedback mechanisms and antagonistic review and specialist agents to improve the end result of what codegen crap gives you. It’s by no means perfect, but it’s a damn sight better than “make no mistakes”, and if the quality of the rust code is really that much of a shitshow, it’s probably not even being reviewed by a human before getting yeeted into prod, let alone the other things I outlined.

SMH they forgot to type „make no mistakes“.

[–] megopie@lemmy.blahaj.zone 1 points 1 day ago (1 children)

Sure, but adding adversarial loops, or, some complex addition to every prompt would increase the token usage massively, thus the cost.

So, why bother with that?

I could very well be wrong, but all indications I’ve seen have been that that the cost of the tokens needed to get something even vaguely acceptable is greater than the cost of just hiring someone, or a group, to do the job. Unless something needs to be done fast due to an immediate concern, and the cost is no object.

Perhaps they run a local model, then tokens are essentially free.

[–] megopie@lemmy.blahaj.zone 1 points 1 day ago (1 children)

Would need a very beefy cluster, and that definitely isn’t free.

[–] bumblebeer@lemmy.world 1 points 1 day ago* (last edited 1 day ago)

Well yes, I'm not saying it's a free lunch. The point is a large up-front investment buys you unlimited tokens in perpetuity for no more than the cost of electricity to power the cluster — which can be surprisingly cheap for UMA machines.

I've swapped off API models entirely and have been able to do a lot more useful work since I don't have to worry about token cost or usage limits. Granted it's slower per task (less tk/s), but overall much more productive, and private.
