Nuclear plants can run with those hyperboloid cooling towers as the sink for waste heat. They are just a lot more expensive to build, run and maintain compared to using river water.

The OpenAI model that broke out of its sandbox and hacked HuggingFace was running without guardrails. To quote the OpenAI post[1]: These deployment safeguards were intentionally not enabled during this evaluation because it was aimed at te

This post does not mention safety at all. What's to stop bad actors from fine tuning open weights to run fully automated genius-level scams personally targeting basically everybody?

I wonder what would happen if you give the model access to edit the conversation history itself? Would it try to fix the "glitches"?

The UX problem is elsewhere I think. Many users probably don't realize that the agent's context window is limited, and that clever compaction is happening regularly to make it seem infinite. But that necessarily means the agent ha

Once you realize how much more efficient solar panels are (compared to plants) at capturing energy from the sun, the next logical question is: could it make sense to synthesize food with the help of electricity from solar power? There is a

You don't even need to double the tokens. Tokens are mapped to vectors right at the input of the LLM, so one of the numbers in that vector could be reserved to represent something like "authority". This way information about

I was thinking the same thing. Perhaps the trade-off made by evolution is about saving energy? In that case it shouldn't be a problem to boost the innate immune system, as long as you have surplus calories to spend. But it could be som

There is not going to be any shortage of plastics in the medium term. Shale oil and gas production in the US produces vast quantities of ethane as a byproduct. This ethane is cracked into ethylene, a feedstock for making plastic. There is a

I can play a pure sine wave tone with a tone generator app, and dial the frequency up until it precisely matches my tinnitus. I originally did this just to determine that frequency. But I noticed a side-effect: if I then turn off the tone g

Those "Thumping great Unix boxes" (or indeed even integrated circuits) didn't exist before the sixties. So it seems that technological revolutions do occur from time to time.

As far as I understand, the "entity list" you are referring to is part of the "Export Administration Regulations", so it restricts sales from the US to restricted entities, not the other way around.

This comes up in every discussion about demographics. But counterintuitively, there are no examples of financial incentives actually fixing this problem. For example, in 2022 Hungary was spending 6.2% of GDP on such incentives[1], but this

When LLMs process tokens, each token is first converted to an embedding vector. (This token to vectors mapping is learned during training.) Since a token itself carries no information about whether it has "authority" or not, I&#x2

The map of planned data centers shows how badly the UK needs to split its single pricing zone for electricity. There should be more incentive to build data centers in the north, where there is plenty of renewable power but limited capacity
