Very impressive! It's faster than some "dumb" apps doing plain old database fetches.

But what are these LPUs optimized for: tensor operations (like Google's TPUs) or LLMs/Transformers architecture?

If it is the latter, how would they/their clients adapt if a new (improved) architecture hits the market?

Lots of comments talking about the model itself. This is Llama 2 70B, a model that has been around for a while now, so we're not seeing anything in terms of model quality (or model flaws) we haven't seen before. What's interesting about this demo is the speed at which it is running, which demonstrates the "Groq LPU™ Inference Engine". That's explained here: https://groq.com/lpu-inference-engine/ > This is the world’s…

this is running on custom hardware, if you’re curious about the underlying architecture check the publication below.

EDIT: i work at Groq, but i’m commenting in a personal capacity.

happy to answer clarifying questions or forward them along to folks who can :)

That's really fast. But it mostly seems to be because they made a custom chip. I want to see an LLM that is so highly optimized that it runs at this speed on more normal hardware.

This isn't running on one chip. It's running on 128, or two racks worth of their kit. https://news.ycombinator.com/item?id=38739106 This doesn't mean much without comparing $ or watts of GPU equivalents

GPUs can't scale single user performance beyond a certain limit. You can throw 100s of GPUs at it but the latency will never be as good.

Thanks, impressive full-stack work. I'm sure this was named long before Musk decided to set 44B and change on fire but at first I confused it with Twitter's own LLM thing.
