> I expect it to cost somewhere in the neighborhood of an experienced dev because that’s the alternative

But there's two ways this could be true: Frontier models costs rise, or (more likely) experience dev costs fall

hazard··on Getting the most out of Opus 5.5 in Claude and Claude Code
It's a pretty old term, to distinguish from e.g. CPU time. This was in common usage even 30 years ago.

Example from 15 years ago: https://stackoverflow.com/questions/7335920/what-specificall...

hazard··on There is more to code review than (automatable) detection
Pangram check on the article: 94% of this text is AI
hazard··on When did Google get so weird?
A key thing that's driving this is the fact that, currently, Gemini is kind of shit compared to the real frontier models from OpenAI and Anthropic. Add on to that the need for Google to serve an absolute insane number of these summaries and have low latency for each one - this means no real thinking time and a comparatively small models.

So it's partially AI, sure, but it's also because you're getting the summaries from what is an extremely stupid AI compared to the "good stuff" that's out there.

hazard··on Garry Tan wants US open-weight AI labs to 'distill' frontier models, too
I worked very briefly at Baseten, and I can say that it was a perpetual annoyance (from an engineering perspective) that customers would complain about issues with their models but we couldn't actually see the inputs/outputs. I don't know about the other providers, but at Baseten they literally weren't stored anywhere.
hazard··on The Last 24 Hours Are the Opening Scene in a Horror Movie
It's a true belief, but that doesn't mean it's valid or correct. Many doomsday cults had true believers, and were able to retcon their beliefs when the predicted day came and went. AI doomers have the luxury of not having committed to a specific date or method (but see https://x.com/archerships/status/2095971206847738362)
hazard··on A Citation to Asimov
In a moment of weakness, I joined a high-IQ group (Triple Nine Society). The whole mailing list was just people having the same political arguments that were on the rest of social media, just with a bigger vocabulary.
hazard··on Dear people who work at the airport
Put an airtag into literally every bag you check. Helps you figure out not just whether they made it on the flight, but also if they ended up at some baggage claim on the other end of the airport instead of the one they were supposed to be at

hazard··on Show HN: Lumabri – What if LLMs worked like Napster?
I recommend reading some foundational materials on federated learning and distributed inference. The fundamental issues are (1) compute (2) latency and (3) security.

On the compute side, you can't load most individual experts into even high-end consumer-grade cards (e.g. RTX 5090) because the weights are simply too big.

On the latency side, you need to ship the activations and wait for the somewhat underpowered cards to actually do the matrix multiplications, then send the results back. This means each token takes hundreds of milliseconds or even more, which is borderline unusable.

Finally if you're running a P2P network, the only way to verify that peers aren't lying to you is to run duplicate calculations - I don't see how SHA-256 or signed model state help here unless I'm missing something (What are you calculating the hash of? What exactly is signing attesting to?).

This is one of the few places where borrowing ideas from cryptocurrencies actually makes sense - you could imagine a system where peers place bonds and forfeit them if they lie about calculations. You can look at projects like Bittensor and others for how these kind of things are currently implemented.

Yes, they say it will be a few milliseconds. This service is squarely targeted at algo trading firms.

hazard··on Professor denounces mass AI fraud on an exam at Brown
After being in the workforce for decades, this whole issue is just so incomprehensible to me.

I went an ungrad school that was top-5 in engineering. But my experience - and in the experience of other people I've talked to - formal undergrad education was, and always has been, a farce. At best, you learn through working on projects that are meaningful to you and learn "how to be an adult" (and later, you learn how to manage the enormous financial debt you acquired). But more typically, it's pure credentialism - no one cares what your grades were, only what school you graduated from.

The amount of actual learning that goes on from classes is minimal, but somehow we can't shift the overton window away from this silly game of grades that don't measure anything meaningful.

After graduating, I've was asked about my grades exactly twice in my life -- once when I applied to a master's program, and at one job interview (the company had a policy of asking about GPA for anyone who graduated less than 10 years ago).

I'm pro-education but anti-school, and all this nonsense makes me this way even more.

hazard··on Modern GPU Programming for MLSys
This looks great, but I'd really like to see associated exercises (and solutions) to make it useful for self-study
hazard··on The Coming Layoffs and the Revenge of the Measurers
> Some engineers, given a fixed token budget, generate exponentially more (and better) output. Other engineers waste their tokens. The variance is enormous, and unlike most performance variance, it is now directly measurable. HR has never had a clearer signal of leverage.

This doesn't make sense to me. "A clearer signal of leverage" implies an objective way to measure software engineering output, which has been the white whale of engineering management for the last 50 years.

hazard··on Show HN: I trained a chess engine to play like humans
The 100-point buckets are fine-tuned on blitz games from users at that Lichess rating. Lichess ratings tend to be a bit high compared to FIDE/USDF/chess.com ratings. There's a good post at https://chessgoals.com/rating-comparison/ comparing them
hazard··on Sam Vimes 'Boots' Theory of Socio-Economic Unfairness
> The reason that the rich were so rich, Vimes reasoned, was because they managed to spend less money.

The premise is just false. The parable might be true when comparing, say, lower class vs lower-middle-class, or lower-middle-class to middle class. But the difference between upper class and middle class is not "spending less money." It's a vastly different net worth that comes from inheritance, building / running businesses, investments, etc.

The boots theory focuses on the costs, but the real difference comes from the income & net worth

hazard··on Ask HN: Is there any interest in a native Qt/C++ Discord client?
I'm always a bit confused by "written in X" as a feature. Rust devs are the worst about this, but not the only offenders.

The language is not a feature!

I'm a C++ programmer, and even I don't care what language the applications I use are written in.

"Fast" is a feature, not that it's in C++

hazard··on Ask HN: What are you working on? (January 2026)
https://www.1e4.ai/

A transformer-based (but not LLM) chess model that plays like a human. The site right now is very rudimentary - no saving games, reviewing games, etc., just playing.

It uses three models: * A move model for what move to make * A clock model for how long to 'think' (inference takes milliseconds, the thinking time is just emulated based on the output of the clock model) * A winner model that predicts the likelihood of each game outcome (white win / black win / draw). If you've seen eval bars when watching chess games online, this isn't quite the same. It's a percentage based outcome, rather than number of centipawns advantage that the usual eval bars use.

Right now it has a model trained on 1700-1800 rating level games from Lichess. You can turn it up and down past that, but I'm working on training models on a wide variety of other rating ranges.

If you're really into computer chess, this is similar to MAIA, but with some extra models and very slightly higher move prediction accuracy compared to the published results of the MAIA-2 paper

hazard··on Ask HN: What have you built with LLMs?
A Twitter filter to take back control of your social media feed from recommendation engines. Put in natural language instructions like "Only show tweets about machine learning, artificial intelligence, and large language models. Hide everything else" and it will filter out all the tweets that you tell it to.

Runs on a local LLM, because even using GPT3 costs would have added up quickly.

Currently requires CUDA and uses a 10.7B model but if anyone wants to try a smaller one and report results let me know on github and I can give some help.

hazard··on Sauna use as a lifestyle practice to extend healthspan
If only the authors had considered this...

> Noncausal mechanisms, including socioeconomic status and reverse causation bias, have been proposed as contributors to the KIHD findings (Kivimaki et al., 2015). Although differences in socioeconomic status may influence sauna access and opportunities for use, the robust dose-dependent associations observed between sauna bathing and sudden cardiac death, coronary artery disease, and cardiovascular events in the KIHD studies are indicative of genuine inverse associations (Laukkanen et al., 2015a). Furthermore, the KIHD studies were conducted in Finland, where sauna use is deeply rooted in the culture, and saunas are readily accessible (Laukkanen et al., 2015a). Similarly, whereas reverse causation bias figures prominently in observational studies and is a valid concern when investigating links between cardiovascular disease and lifestyle, the KIHD findings were adjusted for potential biases, including lifestyle factors such as socioeconomic status, physical activity, and cardiorespiratory fitness (Laukkanen et al., 2015a).
