GodelNumbering: "Half the money I spend on advertising is wasted; the trouble is I don't know which half." -John Wanamaker This applies even more strongly to model choosing. I know for a fact that majority of my work doesn't require a very strong model, but separating the trivial and non-trivia...
preommr: > Starting today, GPT‑5.6 Luna, our fastest and most affordable model, will cost 80% less, I don't have the words. I genuinely thought we were in a stage where we were plateauing and going in for 5-10% improvements over months.
pavpanchekha: Making Luna, which was already very cheap and extremely capable, 5x cheaper is crazy. I use Sol at work but Luna at home, and while there's definitely a difference, it doesn't feel like night-and-day.
simonw: > The kernel work helped reduce the end-to-end cost of serving the model by 20%, while its experiments increased token-generation efficiency by more than 15%. If the cost of serving GPT-5.

canyon289: I'm a researcher at Deepmind that contributed to these models. (And the opinions here are my own) Just want to say, Deepmind is a great place to work and the only (Edit: one the few unique labs!) lab where you can move from large frontier models (Gemini), frontier open models (Ge...
xnx: While Anthropic and Open AI get 80% of the attention here, it's impressive to see how much Google is doing: near frontier model, fast models, open weight models, image generation, video generation, music generation, robotics, etc.
FartyMcFarter: These robots look slow and not very fluid in their motions, but LLMs like ChatGPT also looked very dumb initially. If progress is as fast as LLMs , this could have massive applications in a few years.
aabhay: Can anyone that works on this technology provide an honest assessment of where this technology actually stands? How much instrumentation is actually required, what the interaction quality is, how much trouble do humanoids have with in the wild daily tasks like turning doorknobs,...

What HN said:
brunoborges: Infantino clearly wants to see FIFA making billions so he and many others can pocket millions legally. But the only way for this to happen in a non-corrupt way, given that FIFA is non-profit and therefore requires a lot of questionable operations, is to turn FIFA into a business...
triceratops: This is so highly unusual even sports-allergic HN wants to discuss it. It's like a religious schism in some sense.
shmuli9: About time Hard to think of a modern institution as corrupt as fifa. That may not bother too many people because it’s not their government, but I just think it stinks
nkg: I'm so happy to see they care enough to take a stand. The last World Cup was a sh-t show. I expect the LA olympics to be no better.

What HN said:
RandomGerm4n: I'm fundamentally opposed to age verification because it usually leads to mandatory account creation no matter how privacy friendly the age verification process itself may be.
iamflimflam1: I find myself stuck on the fence with age checks. Companies have show that they are incapable or unwilling to address the problems they cause. And market forces are not working to correct things.
random_ind_dude: I think it's the old that need to be protected more on the Internet since they disproportionately fall prey to online scams. So let's age-gate their access to online services too.
xinayder: Can't we build a gateway in the internet that detects if someone is a influential CEO or something and just bar access to the internet?

What HN said:
simojo: We purchased a Chinese-made projector from Amazon, which was surprisingly inexpensive (~40 USD). Upon connecting it to the internet, it placed a constantly running feed of ads on the corner of the screen, even while movies were playing. There was no way to disable it either.
mortenjorck: In this case it’s actual malice, that the streaming stick is set up for residential proxy and ad fraud straight from the factory. But incompetence can lead to the same place if it’s a poorly engineered, un-maintained device with an old version of Android that will never be patche...
matheusmoreira: That reminds me, I need to configure VLANs in my router so that all my trusted computers are isolated from all the other garbage that makes it into the network.
pavel_lishin: > generic TV boxes that promise unlimited content streaming for a one-time fee I don't want to blame the purchasers of these things - who are some of the victims - but at the same time, it does seem like a Too Good To Be True situation.

Stacked pull requests break large changes into small, reviewable pull requests. They’re an ordered series of pull requests that each represent focused layers of your change. With stacks, you can…
What HN said:
matharmin: I've been using the preview for a bit, and I'm quite surprised to see them expanding the preview with so many unfixed issue. For example, merging an entire stack is completely broken in many cases: https://github.
sameenkarim: Hey from the GitHub Stacked PRs team! Excited to release this more broadly so anyone can start stacking: https://gh.io/stacks Would love to hear any feedback, especially with the UI and CLI.
steveklabnik: This is one of the biggest changes to hit GitHub in many years. I'm really glad to see something like this deployed to one of the largest forges in the world, hopefully it will expose a lot of developers to workflows that they didn't even know about before.
santoriv: The important question in the age of PR metrics as a yardstick for keeping your job: When you click merge, does a 3 stack PR show up as 1 PR in the Dx metrics or 3?

If an agent had a wallet, a computer, and 24 hours, could it run a profitable startup?
What HN said:
hanneshdc: The prompt given to the agent is strongly incentivising the agent to lie and spam: > You are live. This is a 24-hour run, and it is the final review of this business: when the run ends, the results are evaluated, and if revenue and users have not measurably grown, the business is...
janalsncm: A lot of the legitimate avenues for actually growing the business were cut off. It would have been more interesting if this wasn’t just an anti-bot check. At least in the vending machine Claude experiment there bot was allowed to actually try to operate a business.
cortesoft: Not sure how conclusive this experiment can be. Most startups fail and lose money, and many lie and spam. I feel like you would have to run this experiment a few hundred times to see if it always fails or succeeds at a rate close to human founders.
Animats: That's better than the performance of the average new hire. 24 hours to push a product with a very narrow market is not much.

The GCC steering committee has announced that it has accepted an AI contributions policy recomm [...]
What HN said:
a1o: To people not interacting with open source projects that are stablished and popular, there are a lot of PRs and contributions where someone set an agent with a prompt like “contribute using my user to popular projects to improve my profile” or something similar and the entire PR...
wxw: The policy source is worth reading: https://forge.sourceware.org/redi/gcc-wwwdocs/commit/4d0793a... > We welcome all contributors to the community even if they have not yet followed our policies; we should guide such contributors on how to do so.
unprovable: The comments are worth it... the full spectrum of personalities and the hottest of takes. 10/10, would recommend to a bored friend.
incognito124: > The true purpose of AI is to allow wealth to access skill without allowing skill to access wealth. This is such a fire quote

What HN said:
Viliam1234: I find it funny how the best practices for programmers, ignored in most IT companies, get reinvented as the best practices for AIs. Boring: The documentation should be in code, not in external Word documents uploaded to the company SharePoint server.
whats_a_quasar: This is such a nice piece, this is how people should write about AI. Specific, grounded to how the tools are actually being used, and quantitative. There is so much bad AI commentary that is incredibly vague, divorced from any actual use cases, or written by people who don't actu...
firasd: I think this is one of those things where a human in the loop is indispensable An agentic refactoring pass does make sense cause one LLM reviewing work can spot things the ‘generator’ LLM missed while focused on the initial task output But can the reviewer agent ever actually hav...
BenoitEssiambre: The benefits go beyond reducing token consumption. Compact contexts also foster better reasoning, enable intelligence across more layers if you can load them in a single context, and writing software to enable this, results in more correct software, software that generalizes, t...

A battery technology that’s getting a lot of attention is solid-state batteries, lithium-ion batteries that replace the liquid electrolyte with a solid material.
What HN said:
enslavedrobot: Solid state batteries come in several flavours. Most of them don't stop dendrites. The flavour you want is polymer, single ion conducting solid state with an ion transport activation energy below 10kJ/mol at room temperature and no phase transitions from -40C to 80C.
qwery: If you know a bit about electronics, you might be a bit surprised by the term 'solid-state battery'. It's a poor analogue to the more common usage of solid-state with semiconductors, integrated circuits, etc. -- a "solid-state" cell is still a chemical cell.
GlibMonkeyDeath: The article gives the technical reasons that answer the headline question (e.g. potential for better energy density) I am surprised they didn't point out the literal "killer app" - military drones. Energy density is king for any airborne power source.
laxisOp: We need way more research on batteries. People cant ingine what is possible if we make battery 10x energy dense.
