With 3,584 GPUs, or 448 Nodes w/ 8GPUs/node. At 5 nodes/rack, that's 90 racks. I looked and found and old listing for Lambda's Echelon racks about $650k. So the infra cost is a little under $6 million.

If you bought the $2/hr H100 instance they offer, that would cost ~$330k. Pricey, but not too bad.

My bigger hope is that with cheaper compute we can see more architecture search and designs. A lot of different architectures are relatively unexplored due to computational constraints and are typically performed by smaller labs so they don't scale and it is kinda hard to compare models when we're just looking at performance benchmarks and not considering other factors. We definitely don't want big labs to railroad our research directions. Feels weird that a huge amount of NLP is based on using pretrained models and tuning them. Vision is going this way too. You basically can't get published without being SOTA so you basically have to modify an existing model or have a multi-million dollar lab and train from scratch. Really weird to expect academia to compete with big labs and really weird to not let academia take "bigger risks" and explore less popular areas. It is vital to our research path that we don't force everything onto a single track.

H100s are now around 30k USD if you're lucky, going up to 40k on Ebay/Amazon.

3,584 GPUs at $30,000 is $104,550,000 USD only in GPUs.

We're talking about building a server, so usually availability is different than to a home consumer. But fwiw lambda has their Node for 330k (which gets pretty close to that price), whereas the A100's are $170k, so double my figure. Especially considering the H100 nodes are 8U instead of 4U. so you need twice as many racks.

30k is to businesses, not consumers. Consumers don't buy H100s.
