The model running well is only one constraint for consumer adoption. The other ones, namely RAM and making the CPU super warm and rapidly draining battery, are another which is much harder to solve.

I'm somewhat bullish on the Edge Computing approach to this. For example, how about a co-op neighborhood LLM rack?

I currently use a TrueNAS as my home server, and I'm sure whatever I replace it with will add HW for local inference and act as my Home Braim for various automations and assistants.

How is “Edge Computing” any different than what the GP was stating about current cloud hosted (eg OpenAI)?

There are different possible approaches here, but for me, the main benefit would be of having control over the model(s) used. Other than that, low latency would be crucial for effective voice interaction.

It'll work about as well as those "wire your neighborhood for Internet as a collective" movements of the 1990s.

In fact, you'll need those to deal with latency issues, if my experience with consumer ISP quality is any indication.

Funny enough, I know two separate groups of people doing that. One in an apartment in SF running a shared Wi-Fi network with VLANs so they don't step on each other's frequencies, and another group sharing WISP infrastructure in semi-rural Utah where they can't convince ISPs to lay fiber. (Although I think the second group now uses that as a backup for Starlink.)

Yes, UBNT nanobeam 5ac AC wireless[1] is pretty dirt cheap. Can get a pair for about $199 for a wireless P2P link that can work over several kilometers. I have deployed a number of these myself, along with more high bandwidth airFiber stuff.

Why would you do that, and when else has it worked?

I would much rather send my personal information to Microsoft and the NSA than people in my neighborhood

what sort of applications are you thinking? live translations?

There won't, because there's no money in it

There is for whichever company wants to make use of it - say for example LLM-powered NPCs in singleplayer video games (which I'm working on) - pretty much economically unviable with the current model if you want to run everything on the cloud.

You're selling a game once rather than selling a subscription, so you're locked in to paying for cloud-based LLM services indefinitely, unless you want to shut the game down after X years, which really annoys people. Also, you're incentivised to be stingy with the LLM-based features because the more you use it the more it costs you, but by running it locally you can offload that cost to the consumer.

would love to learn more and help out on NPCs llms. What sort of performance hit are you seeing?

Sure, here's my writeup about it: https://jgibbs.dev/blogs/local-llm-npcs-in-unreal-engine. There's barely any performance hit, only a slight hitch when it starts generating a response.

There’s indeed a lot of GPU time not utilised even by modern games. I can definitely imagine new games utilising llms much more even and with local inference option.

At some point soon, LLMs matching current SOTA will run locally in a browser. If applications for LLMs emerge, having one available will be table stakes.

I think in 3-5 years we will have way more competition in the GPU space and maybe even affordable ASICs on the market. Alternatively we may see CPUs gain AI oriented vector acceleration. Either way I expect it to be cheaper in the near future to run large models locally.

That being said your less technical users will probably still use them remotely, and the very largest models will also probably be hosted just because of the capital cost. It doesn’t make sense to spring for a super high end rig to run a massive model locally unless you are using it very very heavily or are a serious homelab enthusiast willing to shell out some bucks.

Of course there are wildcards here like breakthroughs in model efficiency, compression, or distributed execution and training. Any of that could change the game. I get the sense that we really don’t know how far we are from optimal efficiency right now. There may be far more efficient architectures or ways of compressing these things.

> maybe even affordable ASICs on the market

Part of me envisions a Coral-like device, but the kicker/difficulty/cost problem is always going to be fast, big memory. I think that puts a bit of a price floor on some of it. Can't wait to be wrong though!

There seems to be a lot of potential for efficiency gains in models where a much smaller model can achieve the same results. On the other end computing hardware always gets faster and GPU size/performance has been growing exponentially for a good long while.

Local inference is quite inevitable.
