Keen for this also. Been having issues getting a smooth voice experience from HA to ChatGPT. I dont like the whole wakeword concept for the receiver either. I think theres work to be done on the whole stack.

you can use a physical button instead of wakeword.

Doesnt suit my use case sadly.

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

Please not. There were some bots (or karma-farming users) doing this and yuck, was it annoying.

Counterpoint: if somebody builds that elsewhere, that's one fewer person posting slop on HN proper

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.

Look at the specs of this Orange Pi 6+ board - dedicated 30 TPU NPU.

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."

I unironically want this.

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…

The sota chatbots are getting more and more functionality that is not just LLM inference. They can search the web, process files, integrate with other apps. I think that's why most people will consider local LLMs to be insufficient very soon.

One easy way to test different models is purchase $20 worth of tokens from one of the Open Router-like sites. This will let you asks tons of questions and try out lots of models. Realistically, the biggest models you can run at a reasonable price right now are quantized versions of things like the Qwen3 30B A3B family. A 4-bit quantized version fits in roughly 15GB of RAM. This will run very nicely on something like…

> (If you have a bunch of money and patience, you can also run something like GPT OSS 120B or GLM 4.5 Air locally.) Don't need patience for these, just money. A single RTX 6000 Pro runs those great and super fast.

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

I feel like calling it a “30B” model is slightly disingenuous. It’s a 30B-A3B. So only 3B parameters is active at a given time. While still impressive nevertheless, being able to get 8T/s for a “A3B” compared to a dense 30B is very different.

What does it mean that only 3B parameters are active at a time? Also any indication of whether this was purely CPU or if it’s using the Pi’s GPU?

I've asked Gemini about it the other day(I'm dumb and shameless). Apparently it means that the model branches into bunch of 3B sections in the middle and joins at both ends, totaling in parameters at 30B. This means computational footprint reduces to (bottom "router" parts + 3B + top parts) of effectively-5B or whatever specific to that model implied by "3B", rather than the full 30B.

MoE models still operate on token-by-token basis, i.e. "pot/at/o" -> "12345/7654/8472". "Experts" are selected on per-token basis, not per-interation, so "expert" naming might be a bit of a misnomer, or marketing.

But that's just software that also runs fine locally. A few tools with a local LLM can do it.

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.

In this context by "real time" people usually mean "as fast as I can read the reply", so, 0.0002 tokens per minute would not be considered "real time".

Real time typically means guaranteed reaction time below 30ms, because slower reactions will make the body through up.
