If I followed the links correctly this benchmark was made on a 16xH200. At current prices I'd assume that is a system price of around $750,000. The year has 86400*365 = 31536000 seconds. Thus 63072000000 tokens can be generated. As pricing is usually given per 1M tokens generated, this is 63072 such packages. Now lets write off the investment over 3 years, 250,000/63072 = 3.96. So almost $4 per 1M tokens generated wi…

Now all we need is better support for AMD gpus, both CDNA and RDNA types

You can run vLLM with AMD GPUs supported by ROCm: https://rocm.docs.amd.com/en/latest/how-to/rocm-for-ai/infer...

However from experience with an AMD Strix Halo, a couple of caveats: it's drastically slower than Ollama (tested over a few weeks, always using the official AMD vLLM nightly releases), and not all GPUs were supported for all models (but that has been fixed).

The VC money is there until they can solve the optimization problems

Nope - i live in one of the most expensive areas, and even the residential price has averaged 18c/kWh delivered including taxes. Businesses get a lower basic rate and also don't pay the VAT, so it works out around 13c/kWh for them.

That's excluding tax, net prices around 0.20-0.30 EUR / Kwh we common.

I updated my comment to include my personal delivered rate including VAT - also note that businesses (like a data center) don't pay the VAT and have substantially reduced delivery fees at high voltage

Impressive performance work. It's interesting that you still see these 40+% perf gains like this. Makes you think that you will continue to see the costs for a fixed level of "intelligence" dropping.

vLLM needs to perform similar operations to an operating system. If you write an operating system in Python you will have scope for many 40% improvements all over the place and in the end it won’t be Python anymore, at least under the hood it won’t be.

It's not about the python at all. Optimization techniques are on a completely different level, on the level of the chip and/or hw platform and finding ways to utilize them in a max manner by exploiting the intrinsic details about their limitations.
