Comparing GPT-4.1 against other models in "did code change cause this incident"
by lawrjone | 2025-04-15 20:49:00+00:00
We've been testing GPT-4.1 in our investigation system, which is used to triage and debug production incidents.

I thought it would be useful to share, as we have evaluation metrics and scorecards for investigations, so you can see how real-world performance compares between models.

I've written the post on LinkedIn so I could share a picture of the scorecards and how they compare:

https://www.linkedin.com/posts/lawrence2jones_like-many-others-we-were-excited-about-openai-activity-7317907307634323457-FdL7

Our takeaways were:

- 4.1 is much fussier than Sonnet 3.7 at claiming a code change caused an incident, leading to a drop (38%) in recall

- When 4.1 does suggest a PR caused an incident, it's right 33% more than Sonnet 3.7

- 4.1 blows 4o out the water, with 4o finding just 3/31 of the code changes in our dataset, showing how much of an upgrade 4.1 is on this task

In short, 4.1 is a totally different beast to 4o when it comes to software tasks, and at a much lower price-point than Sonnet 3.7 we'll be considering it carefully across our agents.

We are also yet to find a metric where 4.1 is worse than 4o, so at minimum this release means >20% cost savings for us.

Hopefully useful to people!

How do you stop doing that if it's a habit you find out is very ingrained in you?

EG.. You are angry at me because I doubled parked. I tell you that the spot I pick was the only one available at the time I took it, and if that is no longer the case(cars have moved) it's not my problem. You are upset about something you do not have the right to be upset about.

I understand the above example is obviously...stupid. I am the stupid person that will argue with you that I didn't do anything wrong, since at that moment in time it was the only option available.

My question is.. how can I stop being like this? It's not good in my life, and negatively impacts my closest relationships.

> No, it's still stupid.

It doesn't serve the goals you think it should, that's not necessarily stupid.

> High corruption leads to weaker economic performance (eg compare red vs blue states).

Yes, but the people who are pursuing corruption don't care about maximizing aggregate economic performance, they care about maximizing their power over others, which is isn't the same as "economic performance" and, to the extent that it related to economic performance, doesn't have any necessary relation to a broad aggregate, its more concerned with very specific aspects of relative distribution.

I disagree with this. Everybody wears clothes. Everybody eats food.

You can't put a monetary value on a t-shirt, because people will buy them anyways. Who is to say that t-shirts aren't $60? People only think that t-shirts are "low value" because we have offshored the labor and are used to very low prices. Meanwhile I bet most Americans can't even sew.

Thank you so much, really appreciate the thoughtful feedback and questions. Glad the idea resonates.

To answer your points:

For native speakers, we’re focusing on matching them with people learning their language and who speak the language they are learning. So it becomes a fair exchange, and both sides benefit. That buddy system idea is exactly the approach we’re taking.

We’re also thinking about adding optional tags like “casual,” “travel,” or “business” to help guide conversations and avoid awkward starts. Icebreakers could be a nice touch too.

For safety, we’re taking moderation seriously. There will be a reporting system in place from the start, and we’re planning to add basic rating features and eventually moderation tools to detect and prevent bad behavior.

Thanks again for the support. I’ll definitely share when the MVP is live. Would love to have you try it.

I received really heartfelt (to me) and sincere life advice on 4chan. I think the fact that it's anonymous without a real karma/voting system means there's a lot less ego-driven, self-centered posting. People don't try to attack as much or have bitter back-and-forths as much as twitter, reddit. They might argue for a bit and then just say f it and move on. But there's no motivation for ragebait, karma farming like there is on twitter.
Why do Big Corps get trademarks of every day words?
by lexokoh | 2025-04-15 20:50:39+00:00
Following the Decease letter from Figma to Loveable on the "Dev Mode" trademark. It's ridiculous, but it's common.

Basecamp owns the "Hey" trademark. (I received a decease email from them when I was building hey.new)

Oracle owns the "MySQL" trademark.

So, I'm not surprised that Figma owns the trademark "Dev Mode."

Big Corps owns trademarks all the time. It's not right, but they do for several reasons. Most don't make sense to me.

Maybe IP? What do you think?

I won't be surprised if OpenAI trademarks "Chat" and "AI".

I'm a huge fan of Cohere. We were highlighted in the launch post and use their V3 text embeddings in production: https://www.searchagora.com/

We're switching to the V4 to store unified embeddings of our products. From the early tests we ran, this should help with edge case relevancy (i.e. when a product's image and text mismatch, thus creating a greater need for multi-modal embeddings) and improve our search speed by ~100ms.

> create much less landfill

But maybe bought from a salesman with a Humvee and a artisan that spends every last cent on overseas travel

The issue is that trying to analyse the breakdown of $ by environmental outcomes is hard.

There is a lot of propoganda about how to be environmentally sound. We tend to pick one dimension like trash output. We lack the information to be able to make better balanced decisions, for example sometimes the throwaway thing is better for the environment.

> expensive shelfs

I think that example is selection bias. I'm sure you can think of plenty of expensively wasteful examples too (it's easiest to look at other people to find that).

Counter-factual: I made some shelves from waste-stream offcuts, and other shelves were going to be thrown out. Plus costs to paint them (much much less than even the cheapest of new shelves).

The part that might take some work is matching the motion correctly, with a pixelated area or blacked out rectangle it doesn't matter if it's exactly sized or moving pixel perfectly with the window. I haven't done any video editing in 20 years, so maybe that's not very difficult today?

That moving pixelation look is definitely cooler though. If you wanted to keep it without leaking data you could do the motion tracked screenshot step first (not pixelated, but text all replaced by lorem ipsum or similar) and then run the pixelation over top of that.

If any of you nerds reading this are into video editing, please steal this idea and automate it.

Given the fact that LLMs like most neural networks work by passing their input through layers, wouldn't this be expected? There's no going back to an earlier layer and if the first layers are in some sense needed for "translating" [0] to English, any other functionality in those layers cannot be used.

[0] I am simplifying here, but it would make sense for an LLM to learn this, even though the intermediate representation is not exactly English, given the fact that much of the internet in English and the empirical fact that they are good at translating.

I think I like the idea, but I have to ask a favor: Please stop the animated banner text!

I'm getting tired of how many web developers don't realize that endless, unstoppable animation is a huge accessibility issue. My brain apparently has some deep programming to follow anything that moves, so I can't actually read anything about the project without straining my brain. For reference, I'm autistic. Many neurodivergent people have similar issues. So, unintentionally, you're excluding people that might enjoy this.

In the EO language there is no "whichever is greater", the shipping company picks (note this all specifically for de minimis, <$800 value, packages).

In EO 14256:

> Transportation carriers delivering shipments to the United States from the PRC or Hong Kong sent through the international postal network must collect and remit duties to CBP under the approach outlined in either subsection (c)(i) or subsection (c)(ii) of this section. Transportation carriers must apply the same duty collection methodology to all shipments; however, transportation carriers may change their collection methodology once a month or on such other periodic timeframe as CBP determines appropriate, upon providing 24-hour notice to CBP.

(c)(i) is Ad Valorem Duty and (c)(ii) is Specific Duty

If the administration was even remotely competent, this would be scary. There is EASILY a list of things that they could do if they truly cared about going full authoritarian.

But when they start doing stuff like tarrifs for no reason what so ever, to the point where even Musk thinks its stupid, the situation is sad more than scary. US has lost its edge for literally nothing in return.

> Not anymore. Used to be a Christian nation with a mix of European culture - that's what it was founded on. This started to change after 1965 Immigration Act.

1. America was never a Christian nation. That's a far-right populist rewriting of history.

2. 1965 was quite a while ago! But even before then, European culture is extremely varied. Not to mention Chinese and Japanese immigrants before. It was a melting pot even then.

> They are good because they preserve the nation's people. They help the nation.

This means nothing, by the way. This is the problem with populist messaging. It's populist because it sounds good, but it also has to appeal to the lowest common denominator.

There's no substance, no logic, no reasoning. Just promises, built on appealing to emotions. A sense of national pride, of sovereignty. Past that, the details are TBD.

> Economic prosperity at the cost of your nation is not worth it. We don't need cheap food delivery.

Once again, this means nothing. "At the cost of your nation" is just a populist message, something a bit Hitler-y. But it's not an actual argument. What, specifically, is being lost?

> And what has this economical prosperity brought you? Rampant crime, homelessness, zombie cities, healthcare accessible only to the wealthy, one of the biggest wealth inequality in the developed world.

On the topic of crime because far-right populists just can't help but lie - crime in the US is down and has been trending down for decades. People like Trump will claim the opposite, because they are liars and in order to form a populist message you have to appeal to emotions (see above).

It's easy to convince people something needs to be done when you cater to their sense of survival. Of course, it's just not true, blatantly. It's not misinformation or disinformation - it is dishonesty. The same is true for many European nations. You're free to look at crime statistics. But, more importantly than being dishonest, the horse begets the carriage. Why does removing brown people fix crime? What's the mechanism for that? Is it because you propose, by their blood, they are more susceptible to crime? Ah, and there comes the racism I mentioned earlier. With far-right populist ideology, it always comes, if you just give it a squeeze. I have no doubt now you will say no, that's not the reason why, but I don't really care.

And, on some other topics:

1. Healthcare is the most accessible it's ever been in the US takes to the ACA. The far-right wants to dismantle this. This isn't a matter up for debate either, so please don't bother.

2. Wealth inequality is high because of the far-right repeatedly failing to tax the rich and letting them engage in anti-competitive behavior. Under populist far-right leaders like Trump, the wealth inequality will only increase.

I've dabbled a little in game development projects. But how does someone actually get started on a project like re-implementing a game like TR?

I suppose the PC release helps, you can disassemble that. Perhaps find editors online to determine the asset structure. But it must surely be an enormous project and no end of trial and error to do it that way.

> The labor wages themselves are a factor, but an increasingly minor factor in product costs.

Not disagree with your main points, but labor inputs are still very much a huge part of product costs, and often the biggest driver of where to build a new factory when a company is scaling up. Companies aim to build their new factories wherever there's a sufficient pool of cheap labor with the necessary skills.

I did some digging and the hacker posted which exploit he used.

Apparently some boards allowed uploading PDF files, but the site never checked if the PDF file was an actual PDF file. Once a PDF file was uploaded it was passed to a version of Ghostscript from 2012 which would generate a thumbnail. So the attacker found an exploit where uploading a PDF with the right PostScript commands could give the attacker shell access.

Maybe the US just has just lost its fascination.

I mean, we are bombarded with America's stupidity amost every day, why spend our vacation there? The whole travel experience just sucks anyway and at the border you are treated like the next Osama Bin Laden.

Compare this to travelling inside the EU, where we enjoy complete freedom of travel, good food, nice cities, safety and general rationality.

It's just way more pleasant over here.

Sure. My email is in my profile - send me an email from any email address (it can be disposable or whatever) and I'll send back the videos.

In the meantime, here's the UK's report on the atrocities: https://www.7octparliamentarycommission.co.uk/

> "irrefutable record of the terrorists' crimes of homicide, rape, kidnapping and torture. As the report notes, this was "the largest single massacre of Jewish people since the Holocaust".

The UN report (which was early on): https://www.un.org/unispal/document/coi-attacks-7october2023...

> The Special Representative of the Secretary-General (SRSG) on Sexual Violence in Conflict, Pramila Patten, found after a mission to Israel in January to February 2024 reasonable grounds to believe that conflict-related sexual violence occurred at several locations, including in the form of rape and gang rape

And the UN issuing an update noting sexual rape of held hostages: https://news.un.org/en/story/2024/03/1147217

> The team also found a pattern of victims - mostly women - found fully or partially naked, bound and shot across multiple locations which “may be indicative of some forms of sexual violence”.

And several of the hostages (eg Aviva Siegal) reported being sexually assaulted including gang rape.

Unfortunately, this is an incorrect response from a front-line AI support bot. We did roll out a change to improve the security of sessions, and we're investigating to see if it caused any problems with session invalidation. We also do provide a UI for seeing active sessions at cursor.com/settings.

>This has to be bait.

Everything in my post is true. And I do not intend to be inflammatory.

>How can you possibly justify this?

Easy. I buy the books from authors I respect. Books are mostly passion projects anyway and most of the ones I read are from authors who absolutely do not make a living from them or are dead.

The other category of books are scientific publishers I hate all of them and they do not deserve a single cent from me. I would feel bad giving them any money at all. I also am already paying their authors with my taxes.

For shows. I hate most of them anyway and I wouldn't mind if corporate entertainment were gone.

For musicians. I see it the same as with books. I support the artists I like and I give them money for products they put out.

Nobody owes an artist his existence. Especially since most artists are commercial failures any way and somehow that does not threaten the art itself.

Also consider YouTube. Do you think YouTubers would care about IP laws being abolished? Their products are available for free anyways and they commercialize themselves in many different ways.

> How can you possibly compare Britain in 1945 to the US today? By 1945 Britain had spent all of its gold reserves, it had stopped exporting anything due to the war but as an island nation needed massive imports to survive. It had a restless global empire that was costing huge sums of money to maintain and a massive military left over from the war. The situation was so bad that food was rationed for years after the war and there were coal shortages.

Up until you got to the rationing and coal shortages I think the parallels with the contemporary US are pretty obvious.

If it is against the wishes of the people in the video, yes, yes it is.

E: Never thought I'd see the day I'm downvoted for saying un-blurring porn of people who made porn under the assumption that it would be blurred (and may not have made that same decision without that context) is unethical, on HN of all places, but times are strange I guess.

> Note that modern France is the Fifth Republic so that's a whole lot of turmoil given how relatively recently they killed their last king.

Their last king wasn't killed by the French, but died in exile in England, and was one of three (or four) kings (Louis XVIII, Charles X, (arguably Henry V), and Louis Phillippe, who reigned between the First Empire (and consequently also after the First Republic) and the Second Republic (and consequently also before the Second Empire.)

Their last monarch was even later, and also wasn't killed by the French, but died in exile in England. The series of governments after the last monarch includes only the Third through Fifth Republics (and, depending on how you look at it, the Vichy regime between the Third and Fourth Republics.)

And IIRC there wasn't much substantive difference between the Third and Fourth Republic; the latter was basically a restoration of the former after France was freed from German occupation, not a change in governing philosophy by the French people, so you could argue that there were as few as two substantively different French systems of government after the last monarch was deposed.

Optimal relative to what? And more seriously, name any large program, government or corporate, that is "optimal".

Google, Duolingo, and DataBricks are three multibillion dollar tech companies based in part on NSF research. The return on investment from NSF-funded research spinning out into companies is enormous.

While the system could use some tuning, it also works pretty well as is. Don't let the perfect be the enemy of the good.

Should also look at the USA's vast operation to help Russia's war on Ukraine. Trump is still blaming Zelensky for starting the war, and his administration is calling Russia's attack on civilians an unfortunate mistake.

Never thought I would live long enough to see Republicans align with Russia and North Korea and possibly Iran (they are working on it) while framing the EU/Canada as the enemy.

One of the central problems of left-wing ideology is placing (or more accurately, weaponizing) subjective emotion over objective truth, moral or otherwise. I'm sorry if that's painful to hear, but it is true.

> science and rational thinking that you seem to abhor.

What did I say that gave you that impression? Au contraire.

Modern life, science, rational thinking -- these are not products of left-wing political, moral, or social ideology, not even a little bit. I'm curious how you arrived at that viewpoint, which is incoherent.

Perhaps that which is not currently right-coded is leftist to you, but political coding is a disparate concept from the propositions upon which worldviews are built.

> results are so obviously and immediately measurable

Ehm… not really – especially not the "obviously" part :)

Controlled or even abusive coaching can sometimes lead to better short-term results, but often at the cost of athletes’ mental health and long-term performance.

What’s worse, coaching culture in many countries falls victim to the "regression to the mean" fallacy. I’m sure HN readers are familiar with it, but most coaches aren’t – and they’re not trained to adjust their intuition accordingly.

Coaches tend to praise athletes when they perform well and criticize them when they don’t. But statistically, if an athlete has an unusually good day in practice, they’re likely to perform worse next time. And if they’re having a rough day, odds are they’ll improve next time. That’s just the nature of sports practice.

This creates a repeating pattern: praise followed by worse results, and criticism followed by improvement. Over time, this becomes a learned behavior pattern – reinforced by the environment and by other coaches who interpret it as validation of their approach.

I guess that is what makes things somewhat difficult for me. If I could not see my condition, then I wouldn't even know I had it. I have no symptoms that prevent me from doing anything I need to do in life (knock on wood). I am actually more on the mild side of the spectrum of disease severity.

So, that is why I find it unusual that doctors have offered biologics in the past. I do remember one doctor made a comment to me. She said it was unusual that I do not want biologics because most, if not all, of her patients beg for them regardless of the disease severity. Maybe she is getting kickbacks or something? I have no idea.

Basically, that is the root of my question. Are the risks worth it for someone that has maybe 1-2% coverage of lesions across their entire body? Sure, it'd be nice to go from 1-2% to 0%, I guess, but I cannot get a good understanding on the risks.

Those plots are meaningless because countries measure things differently. Many countries for example don't count anyone before they are a year old while the US does. The US shows up very well for life expectancy, yes it costs a lot more to get there the outcomes of the US healthcare system are very good according to your own data (which as I said isn't good data, but it is data)
