Show HN: AIOpt – local-only guardrail for LLM token/cost regressions
by psi0716 | 2026-02-10 19:09:59+00:00
Hi HN — I built this after repeatedly seeing LLM cost regressions slip through review because nothing breaks; it’s just token drift and then a surprise bill.

AIOpt is a local-only CLI + CI gate that:
- uses observed usage as a baseline (usage.jsonl/csv)
- estimates candidate deltas (model/context/output/retry/traffic)
- emits deterministic artifacts + SARIF for GitHub Code Scanning

No server, no uploads.

I’d really appreciate feedback on what would make this more useful in real PR review:
1) What signals/UX make token/cost regressions actionable (beyond “it’s higher”)?
2) Any must-have integrations you’d expect?

An important security measure for who, though? The servers at the bank should "never trust the client" in case the attestation is bypassed or compromised, which is always a risk at scale.

If it's an important safety measure _for me_, shouldn't I get to decide whether I need it based on context?

I think it's fair for banks to apply different risk scores based on the signals they have available (including attestation state), but I also don't want the financial system, government & big tech platforms to have a hard veto on what devices I compute with.

I'm always a bit surprised by the degree that non-tech people don't understand how much they're being openly and transparently manipulated in various ways. Most of my work has been statistical/quantitative in nature from complex A/B testing setups to dynamic pricing algorithms. Yet so many of the most benign parts of my work in the past unnerve some people.

Measuring human behavior and exploiting it for some hope at profit has been an obvious part of my job description for many years. Yet I've had friends and acquaintances that are shocked when they accidentally realize they're part of an A/B test "Wait, Amazon doesn't show the same thing to everyone!?" I've seen reddit conversations where people are horrified at the idea of custom pricing models (something so mundane it could easily be an interview question). I had a friend once claim a basic statement about what I did at work was a "conspiracy theory" because clearly companies don't really have that much control.

To your point, at work the fact that we're manipulating people algorithmically isn't remotely a secret. Nobody in the room at any of my past jobs has felt a modicum of shame about optimization. The worst part is I have drawn a line multiple times at past jobs (typically to my own detriment), so there are things that even someone as comfortable with this as I am finds go to far. Ironically, I've found it's hard to get non-technical people to care about these because you have to understand the larger context to see just how dangerous they are.

I have ultimately decided to avoid working in the D2C space because inevitably you realize you aren't providing any real value to your user (despite internal sloganeering to the contrary) and very often causing real harm. In the B2B space you're working with customers who you have a real business relationship with, so crass manipulation to move the needle for one month isn't worth the long term harm.

These people are everywhere.

Instagram serves me antisemetic content consistently with no way for me to downvote it. Likewise when it tries to rage bait me with islamophobic shit.

I do not engage or upvote other than taking screenshots and reporting. At this point I just don't open Instagram except for messages from friends

It is incredible that they literally fund selfish assholes to do this. What worse is that they will not reap the vile harvest.

You're following the propaganda, not the reality. Just because Hamas calls them "press" doesn't make them so. And almost nobody will call Hamas on it because that would jeopardize future reporting. And unfortunately having something to report is far more important to "news" organizations than actually reporting the truth. We've even seen The Felon try to do that here--report only what I want if you want to be allowed into press conferences.

Sometimes nature tells us that the questions we are inclined to ask, are flawed questions.

The “What path did the photon take?” question is one of those times. The answer to the question is Mu.

Similar to the questions “How much phlogiston is there in iron?” or “Does sulphur have more earth than air, or more air than earth?”.

Anonymity leads to the multiple accounts issue. Pseudonymity addresses that. Eg: "We don't know the name of the person behind this identifier in real life, but we see we blocked them last year, so we will deny their request to open a new account with us"

You and I agree the moderation here on HN is fantastic. There is a minority of people who would prefer HN allow spam, bigotry, calls to violence, revenge porn, snuff content, etc. A large community - a nation, for example - should have the ability to 'tyrannize' an antisocial minority into enforcing some base level of standards. For example, at a minimum, to prevent a site operator from showing those types of content to users who do not specifically request them.

I was a bit confused as to how everything works until I read it in detail. Really cool tools, but I think one thing that would help in the introduction is: saying explicitly that the generated .md document is for you (the user) to read through, observe the output of the CLI call, and ensure that the output matches what you would expect.

It's basically an automated test, but at a higher abstraction level and with manual verification--using CLI tools rather than a test harness. Really great work!

First, that’s a LOT of money. Very few people can afford that at all and those that can are definitely counting down the days until their last child goes to school.

Second, it’s hard to find a good nanny. Parents live in fear of not getting a good one, having something go wrong and need to scramble for a replacement without missing too much work, etc.

It’s possible but it’s not going to move the mainstream averages because only like 5% of the population does that. If we want to materially change national averages, we should be talking about government daycare filling in the gap before public schooling starts around the country.

If it helps, I don't think that there is anything to be ashamed of to want to try new things even if you recognize it is inadvisable. If there were no physical consequences, I'd like to try all sorts of medicines to see what effect they would have on me.

As a user of Mounjaro, obtained from a doctor, I find the experience very interesting. It has all sorts of weird side effects that I don't expect. As a bioinformatician in training it's great fun to speculate about the causes, pathways, signals, and whatnot that might be involved as this drug perturbs so much stuff in my system.

It's not pleasurable per se, but it is interesting. I have changed my food habits significantly without actually trying. I think I was too impatient to eat to cook if that makes sense. Weirdly, foods taste better to me which I did not expect. I also have found myself really enjoying my hobbies more. This has resulted in a lot of 3d printer filament purchases, so my impulse control may not have been helped much.

As far as experimenting on yourself, it will likely require the cumulative effect of weeks or months to notice changes in non-food habits if such changes occur at all.

There's probably some online doctor that will prescribe this thing to you for several hundred dollars/euros or whatever. You may suffer greatly for your curiosity, though. There are instances of very unpleasant side effects, some of which I experience personally.

I talked to you last month when you posted this. I did end up buying a copy, and it has been somewhat useful.

Three things, it drives me nuts when it migates to the localhost interface, but doesn't migrate back. Either, we need to lock to an interface, or just have the option to remove one.

Two, constantly bouncing in the dock is incredibly annoying and distracting. We don't need more distractions, we need less.

Three, showing the wifi mesh info has actually proven to help, but it would really be even more helpful if you could expand that to rates and more wifi protocols.

They're existing, not really thriving. Artisanal things have become more popular as a hobby, but even people who get into them commercially rarely make real money off of it. The demand exists, but purely as a novelty for people who appreciate those types of things, or perhaps in really niche sub-markets that aren't adequately covered by big businesses. But the artisans aren't directly competing with companies that provide similar goods to them at scale, because it's simply impossible. They've just carved out a niche and sell the experience or the tailoring of what they're making to the small slice of the population who's willing to pay for that.

You can't do this with software. Non-devs don't understand nor appreciate any qualities of software beyond the simplest comprehension of UX. There's no such thing as "hand-made" software. 99% of people don't care about what runs on their computer at all, they only care about the ends, not the means. As long as it appears to do what you want, it's good enough, and good enough is all that's needed by everyone.

I agree, it's the public attitudes that are most disheartening and probably some of the reason young people are less inclined to have children. All over society people are seeing kids as a kind of personal indulgence that shouldn't be allowed to impact other people - whether its a lack of sympathy that parents have higher priorities at work, or looking down on kids who act like kids in public. At the same time parents who let their kids look at screens in public are demonizes, as apparently only kids who are perfectly behaved without distractions should be allowed out.

Meanwhile when dogs bite people there's an outpouring of 'well why did you bother that dog?'.

> These problems are representative of the types of subproblems research mathematicians have to solve to get a “research result”. They are finding that LLMs aren’t that useful for mathematical research because they can’t crush these problems along the way. And I assume they put this doc together because they want that to change :)

Same holds true for IMProofBench problems. This dataset shows nothing new.

> Sometimes you have regulation, but you don't have enforcement of the regulations.

Indeed. Let us quote the Dune books (since they're trending, and for good reason!):

"Good government never depends upon laws, but upon the personal qualities of those who govern. The machinery of government is always subordinate to the will of those who administer that machinery. The most important element of government, therefore, is the method of choosing leaders.
-Law and Governance (The Spacing Guild)"

And if you would let me indulge one more:

"Governments, if they endure, always tend increasingly toward aristocratic forms. No government in history has been known to evade this pattern. And as the aristocracy develops, government tends more and more to act exclusively in the interests of the ruling class: whether that class be hereditary royalty, oligarchs of financial empires, or entrenched bureaucracy.
-Politics as Repeat Phenomenon (Bene Gesserit Training Manual)"

Or it's just a logical continuation of "next quarter problem" thinking. You can lay off a lot of people, juice the number and everything will be fine....for a while. You may even be able to layoff half your people if you're okay with KTLO'ing your business. This works great for companies that are already a monopoly power where you can stagnate and keep your customers and prevent competitors.

> Then please explain why birth rates throughout human history, when life was vastly more difficult and dangerous than it is now, were so much higher?

Because having kids then was a way to increase quality of life. The kids could be put to work from a young age and help make money. Now, with so much modern tech doing physical tasks efficiently, a kid isn't going to add much value and instead is going to be a money sink.
by mcmcmc | 2026-02-10 19:13:42+00:00
The problem mentioned in the parent comment was the volume of fake accounts overloading customer support. If it’s no longer free to create spam accounts for phishing etc, the profitability of scamming will shrink and decrease the incentives. I don’t think feds are exactly slamming the support queue.

More importantly than the bot problem, it would decrease social media usage in the aggregate while also encouraging more competition. Much easier to bootstrap a business if you’re not having to compete with big tech offering the same thing for free because they can subsidize the losses.

It would probably be interesting, but if you are not overweight, the appetite suppression will likely make this not a very healthy or very fun experiment. I started at 5mg in October, and even on that smaller dose I had to force myself to eat even just ~800kcal a day - especially in the early weeks. When you have a lot of weight to lose, that's a pretty welcome effect. When you are already at a healthy weight, not so much. That caloric intake would put most adults into a pretty deep caloric deficit.

I'd suspect if the effects on non-weight indications check out in studies, we might see drugs that could specifically target those effects without also slowing down your digestive tract. Addictions like nicotine and alcoholism and their consequences cost health insurance companies (and us as a society) billions of Euros/Dollars each year, so there'd be a strong incentive to pursue this.

I have a Ph.D. in a field of mathematics in which complex numbers are fundamental, but I have a real philosophical problem with complex numbers. In particular, they arose historically as a tool for solving polynomial equations. Is this the shadow of something natural that we just couldn't see, or just a convenience?

As the "evidence" piles up, in further mathematics, physics, and the interactions of the two, I still never got to the point at the core where I thought complex numbers were a certain fundamental concept, or just a convenient tool for expressing and calculating a variety of things. It's more than just a coincidence, for sure, but the philosophical part of my mind is not at ease with it.

I doubt anyone could make a reply to this comment that would make me feel any better about it. Indeed, I believe real numbers to be completely natural, but far greater mathematicians than I found them objectionable only a hundred years ago, and demonstrated that mathematics is rich and nuanced even when you assume that they don't exist in the form we think of them today.

This issue exists with the parsed case, too. If you're using a database to store data, then the lifecycle of that data is in question as soon as it's used outside of a transaction.

We know that external systems provide certain guarantees, and we rely on them and reason about them, but we unfortunately cannot shove all of our reasoning into the type system.

Indeed, under the hood, everything _is_ just a big blob that gets passed around and referenced, and the compiler is also just a system that enforces preconditions about that data.

>In a massive dataset of human writing, the answer to a question is by far the most common thing to follow a question. A normal conversational reply is the most common thing to follow a conversation opener. While impressive, these things aren't magic.

Obviously, that's the objective, but who's to say you'll reach a goal just because you set it ? And more importantly, who's the say you have any idea how the goal has actually been achieved ?

You don't need to think LLMs are magic to understand we have very little idea of what is going on inside the box.

So let's recap:

- I click skills.

- The first one is WireGuard "... secure routing and key management".

- I'd download it, hook it to this bot running on my system.

- I'd ask the bot to store / manage super-secret keys that protect actual servers with user data and personal details and god knows what...

- The bot follows my commands by spelunking random snippets of markdown, running other programs on my computer, doing web searches, reading what it finds on the web and giving itself more commands to do...

I've only been in tech for like 20 years or so but I feel like either I'm missing something substantial or some kind of madness is happening to people.

I think there is more existential fear that is left unaddressed.

Most commenters in this thread seem to be under the impression that where the agents are right now is where they will be for a while, but will they? And for how long?

$660 billion is expected to be spent on AI infrastructure this year. If the AI agents are already pretty good, what will the models trained in these facilities be capable of?

> Seems like a wonder drug to me. The benefits just keep piling up.

That's a massive red flag. It's a common sign of snake oil when something claims to be the cure for a ton of completely unrelated conditions. While I do think these drugs are actually effective at some things, I also wonder how much they're being overprescribed already. It seems like there's a massive push to try to get insurance to cover the drug for just about anything and everything. I've never seen a drug advertised as aggressively either.

The drug is helping people and improving lives and that's a good thing, but I'm not sure how much of the attention on this drug is just a massive scheme by phrama companies to get sales and how careful doctors and patients are being.

Hey just want to add something.

Vitamin C is a water soluble vitamin. It’s pretty damn hard to get Vitamin C toxicity from overconsumption. It’s not really something to worry about. This is true for all the water soluble vitamins.

This isn’t true for the fat soluble vitamins. Those are Vitamin A, Vitamin E, Vitamin K and Vitamin D.

You can overdose and get toxicity if you consume too much of these. For Vitamin D you can’t overdose from what your body generates from the skin but you can from the oral forms.

Do you really think you have a holographic sign floating above you that tells them you are a citizen? How are you sure you are above suspicion to be an undocumented immigrant? Could you prove you aren't if some goons decided to pick you off the street right now or next time you go for a walk?

It's like Germany in the 1930s again when Jews were required to wear a yellow star on their clothes, but the other way round.

All this is about expanding the reach and normalizing abuse of the power of law enforcement, just like back then after 9/11.

They're not. We already know that. FrontierMath. Yu Tsumura's 553th problem, RealMath benchmark. The list goes on. As I said many times on this thread, there is nothing novel in this benchmark.

This fact that this benchmark is so hyped shows that the community knows nothing, NOTHING, about prior work in this space, which makes me sad.

My wife has had an autoimmune disease that’s caused inflammation for years. Absolutely terrible back pain. She had to rent a motorized scooter when we went to Disney World, and could barely walk a few hundred feet before having to stop and rest for years.

Last year she started Zepbound (tirzepatide) and the inflammation went away, we went to Disney World again and she walked happily all day. Absolutely life changing. She didn’t even lose much weight and this was at the lowest dose.

Interesting.

We started with functions. Functions as list of pairs, functions defined by algebraic expressions, functions plotted on graph paper and after that limits.

Simultaneously, in Physics classes we were being taught using infinitesimals, with the a call back that "you will see this done more formally in your maths classes, but for intuition, infinitesimals will do for now".

Stomach paralysis is apparently a known side effect [1]. There are also lots of anecdotes about lesser (but still foul) digestive surprises that are too unpleasant for me to bother elaborating on here.

I was on my thiccboi swag for the latter half of last year and am presently working it off by rebuilding my fitness base with kettlebells and cardio. I'd rather do this than GLP-1s not because I'm some sort of iron-willed badass so much as I'm simply distrustful of anything that messes with one's metabolism so severely. While these drugs are useful for the morbidly obese and diabetics I simply can't imagine how or why anybody would go on them for aesthetic or off-label purposes.

I was in a fraternity in college, 20 years ago. We put weekly bathroom notes on the inside of the stall doors. Something interesting, something funny, upcoming news. The elected fraternity secretary was responsible for making those weekly, among many other things.

If they were a day late the amount of pestering they would get until the did that weekly job was hilarious. We all got a kick out of them.

Your toilet time can be yours, just don’t fucking read them lol. Back then razr phones were the hotness, nobody sat on a smartphone and had ads blasted at them while they took a shit.
