Someone should make a version of the Hacker News homepage that is just LLM extracts of key article details like this.

Not sure if it is still updating https://hackyournews.com/

Thanks for pointing this out, https://hackyournews.com should be up and running again!

There is a huge market segment waiting here. At least I think there is. Well, at least people like me want this. Ok, tens of dollars can be made at least. It is just missing a critical tipping point. Basically, I want an alexa like device for the home backed by local inference and storage with some standardized components identified: - the interactive devices - all the alexa/google/apple devices out there are this in…

> Well, at least people like me want this.

Yeah because dynamic digital price signs in shops based on what data vendors have about you and AI can extract from it are such fun! Total surveillance. More than what's already happening. Such fun!

Oh... 8 thousand of eurobucks for the thing.

Or 4 thousand for the NVIDIA RTX A6000 which also runs the 120b just fine (quantized).

We need custom inference chips at scale for this imho. Every computer (whatever formfactor/board) should have an inference unit on it so at least inference is efficient and fast and can be offloaded while the cpu is doing something else.

At this point of the timeline compute is cheap, it’s RAM which is basically unavailable.

LLMs are, by definition, real time at any speed. 50,000 tokens per second? Real time. Only 0.0002 tokens per minute? Still real time. Eight tokens per second is "real time" in that sense, but that's also the kind of speeds that we used to mock old video games for, when they would show "computers" but the text would slowly get printed to a screen letter for letter or word for word.

Real time is defined as ‘no slower than some critical speed’, in case of conversation with humans this should be around 10 tok/s including speech synthesis.

I can’t wait to get home and try this on my Pi. Past few months, I’ve been building a fully local agent [0] that runs inference entirely on a Raspberry Pi, and I’ve been extensively testing a plethora of small, open models as part of my studies. This is an incredibly exciting field, and I hope it gains more attention as we shift away from massive, centralized AI platforms and toward improving the performance of local models.

For anyone interested in a comparative review of different models that can run on a Pi, here’s a great article [1] I came across while working on my project.

If you read a lot of comment sections, there are bot accounts showing up on LLM that try to do this constantly. Their output is not great so they get downvoted and spotted quickly.

If you spot any that live longer than a few comments please pass that info to Dan & Tom.

It should participate in all conversations, take initiative and experiment.

"Hey, hey, are you still asleep? Using spare cycles, I have designed an optimal recipe for mashed potatoes, as you mentioned ten days ago. I need you to go get some potatoes."

A local AI system that hears your conversations, identifies problems, and then uses spare cycles to devise solutions for them is actually an incredible idea. I'm never going to give a cloud system the kind of access it would need to do a really good job, but a local one I control? Absolutely.

"Hey, are you still having trouble with[succinct summary of a problem it identified]?" "Yes" "I have a solution that meets your requirements as I understand them, and fits in your budget."

I've just tried replicating this on my Pi 5 16GB, running the latest llama.cpp... and it segfaults: ./build/bin/llama-cli -m "models/Qwen3-30B-A3B-Instruct-2507-Q3_K_S-2.70bpw.gguf" -e --no-mmap -t 4 ...

Would you be able to actually get useful results from it? I'm looking into self hosting LLM's for python/js development. But I dont know if I would get useful results.
