The first GPT-4-class AI model anyone can download has arrived: Llama 405B

Technically correct ™

Before you get your hopes up: Anyone can download it, but very few will be able to actually run it.

What’s the resources requirements for the 405B model? I did some digging but couldn’t find any documentation during my cursory search.

As a general rule of thumb, you need about 1 GB per 1B parameters, so you’re looking at about 405 GB for the full size of the model.

Quantization can compress it down to 1/2 or 1/4 that, but “makes it stupider” as a result.

Typically you need about 1GB graphics RAM for each billion parameters (i.e. one byte per parameter). This is a 405B parameter model. Ouch.

Edit: you can try quantizing it. This reduces the amount of memory required per parameter to 4 bits, 2 bits or even 1 bit. As you reduce the size, the performance of the model can suffer. So in the extreme case you might be able to run this in under 64GB of graphics RAM.

When the 8 bit quants hit, you could probably lease a 128GB system on runpod.

Can you run this in a distributed manner, like with kubernetes and lots of smaller machines?

Or you could run it via cpu and ram at a much slower rate.

At work we habe a small cluster totalling around 4TB of RAM

It has 4 cooling units, a m3 of PSUs and it must take something like 30 m2 of space

Typically you need about 1GB graphics RAM for each billion parameters (i.e. one byte per parameter). This is a 405B parameter model.

Ypu mean my 4090 isn’t good enough 🤣😂

According to huggingface, you can run a 34B model using 22.4GBs of RAM max. That’s a RTX 3090 Ti.

Hmm, I probably have that much distributed across my network… maybe I should look into some way of distributing it across multiple gpu.

Frak, just counted and I only have 270gb installed. Approx 40gb more if I install some of the deprecated cards in any spare pcie slots i can find.

405b ain’t running local unless you got a proepr set up is enterpise grade lol

I think 70b is possible but I haven’t find anyone confirming it yet

Also would like to know specs on whoever did it

I’ve run quantized 70B models on CPU with 32 gigs but it is very slow

I regularly run llama3 70b unqantized on two P40s and CPU at like 7tokens/s. It’s usable but not very fast.

This would probably run on a a6000 right?

Edit: nope I think I’m off by an order of magnitude

“an order of magnitude” still feels like an understatement LOL

My 35b models come out at like Morse code speed on my 7800XT, but at least it does work?

When the RTX 9090 Ti comes, anyone who can afford it will be able to run it.

That doesn’t sound like much of a change from the situation right now.

So does OSM data. Everyone can download the whole earth but to serve it and provide routing/path planning at scale takes a whole other skill and resources. It’s a good thing that they are willing to open source their model in the first place.

Wake me up when it works offline “The Llama 3.1 models are available for download through Meta’s own website and on Hugging Face. They both require providing contact information and agreeing to a license and an acceptable use policy, which means that Meta can technically legally pull the rug out from under your use of Llama 3.1 or its outputs at any time.”

I was able to set up small one via open webui.

It did ask to make an account but I didn’t see any pinging home when I did it.

What am I missing here?

Through meta…

That’s where I stop caring

It’s available through ollama already. i am running the 8b model on my little server with it’s 3070 as of right now.

It’s really impressive for a 8b model

Intriguing. Is that an 8gb card? Might have to try this after all

Yup, 8GB card

Its my old one from the gaming PC after switching to AMD.

It now serves as my little AI hub and whisper server for home assistant

WAKE UP!

It works offline. When you use with ollama, you don’t have to register or agree to anything.

Once you have downloaded it, it will keep on working, meta can’t shut it down.

Well, yes and no. See the other comment, 64 GB VRAM at the lowest setting.

Oh, sure. For the 405B model it’s absolutely infeasible to host it yourself. But for the smaller models (70B and 8B), it can work.

I was mostly replying to the part where they claimed meta can take it away from you at any point - which is simply not true.

I’m running 3.1 8b as we speak via ollama totally offline and gave info to nobody.

Did anyone get 70b to run locally?

If so what, what hardware specs?

Afaik you need about 40GB of vram for a 70b model.

Can’t you offload some of it to RAM?

Same requirements, but much slower.

Yo this is big. In both that it is momentous, and holy shit that’s a lot of parameters. How many GB is this model?? I’d be able to run it if I had an few extra $10k bills lying around to buy the required hardware.

That’s some thick model

Time to buy a thread ripper and 800gb of ram so that I can run this model at 1 token per hour.

Kind of petty from Zuck not to roll it out in Europe due to the digital services act… But also kind of weird since it’s open source? What’s stopping anyone from downloading the model and creating a web ui for Europe users?
