I am planning to buy a new GPU. If the GPU has 16GB of VRAM, and the model is 70GB, can it still run well? Also, does it run considerably better than on a GPU with 12GB of VRAM? I run Ollama locally, mixtral works well (7B, 3.4GB) on a 1080ti, but the 24.6GB version is a bit slow (still usable, but has a noticeable start-up time).

Get 2 pre-owned 3090s. You will easily be able to run 70b or even 120b quantized models.

I’d like to know how Nancy Pelosi, who sure as hell doesn’t know what Apache Spark is, bought $1 million worth (and maybe $5million) of Databricks stock days ago. https://www.dailymail.co.uk/sciencetech/article-13228859/amp...

You know she has advisors, right?

Just curious, what business benefit will Databricks get by spending potentially millions of dollars on an open LLM?

Databricks is trying to go all-in on convincing organizations they need to use in-house models, and therefore pay they to provide LLMOps. They're so far into this that their CTO co-authored a borderline dishonest study which got a ton of traction last summer trying to discredit GPT-4: https://arxiv.org/pdf/2307.09009.pdf

I can see a business model for inhouse LLM models: Training a model on the knowledge about their products and then somehow getting that knowledge into a generally available LLM platform.

I recently tried to ask Google to explain to me how to delete sender-recorded voice-message I had created from WhatsApp. I got totally erroneous results back. Maybe it was because that is a rather new feature in WhatsApp.

It would be in the interests of WhatsApp to get accurate answers about it into Google's LLM. So Google might make a deal with them requiring WhatsApp to pay Google for regular updates about the up-to-date features of What's App into Google. The owner of What's App Meta of course is competition to Google so Google may not much care of providing up to date info about WhatsApp in their LLM. But they might if Meta paid them.

While GPUs are still the kings of speed, if you are worried about VRAM I do recommend a maxed out Mac Studio. Llama.cpp + quantized models on Apple Silicon is an incredible experience, and having 192 GB of unified memory to work with means you can run models that just aren't feasible on a home GPU setup. It really boils down to what type of local development you want to do. I'm mostly experimenting with things where…

Aren't the Macs good for inference but not for training or fine tuning?

Earlier quoted context omitted.

> This is a source-available model, not an open model. To me, "source available" implies that everything you need to reproduce the model is also available, and that doesn't appear to be the case. How is the resulting model more "free as in freedom" than a compiled binary?

I don't think it's possible to have an "open training data" model because it would get DMCA'd immediately and open you up to lawsuits from everyone who found their works in the training set. I hope we can fix the legal landscape to enable publicly sharing training data but I can't really judge the companies keeping it a secret today.

> I don't think it's possible to have an "open training data" model because it would get DMCA'd immediately…

This isn't a problem because OpenAI says, "training AI models using publicly available internet materials is fair use". /s

this proves that all llm models converge to a certain point when trained on the same data. ie, there is really no differentiation between one model or the other. Claims about out-performance on tasks are just that, claims. the next iteration of llama or mixtral will converge. LLMs seem to evolve like linux/windows or ios/android with not much differentiation in the foundation models.

There's at least an argument to be made that this is because all the models are heavily trained on GPT-4 outputs (or whatever the SOTA happens to be during training). All those models are, in a way, a product of inbreeding.

Looks like someone has got DBRX running on an M2 Ultra already: https://x.com/awnihannun/status/1773024954667184196?s=20

That's great, but it did not really write the program that the human asked it to do. :)

> The model requires ~264GB of RAM This feels as crazy as Grok. Was there a generation of models recently where we decided to just crank on the parameter count?

If you read their blog post, they mention it was pretrained on 12 Trillion tokens of text. That is ~5x the amount of the llama2 training runs.

From that, it seems somewhat likely we've hit the wall on improving <X B parameter LLMs by simply scaling up the training data, which basically forces everyone to continue scaling up if they want to keep up with SOTA.

I think the insinuation is insider trading due to the timing, advised or not.

What does it mean to have less active parameters (36B) than the full model size (132B) and what impact does that have on memory and latency? It seems like this is because it is an MoE model?

Means that it’s a mixture of experts model with 132B parameters in total, but a subset of 36B parameters are used / selected in each forward pass, depending on the context. The parameters not used / selected for generating a particular token belong to “experts” that were deemed not very good at predicting the next token in the current context, but could be used / selected e.g. for the next token.

Do the 132B params need to be loaded in GPU memory, or only the 36B?
