as not custom chips like Grog and Cerebras. Did you expect a single GPU chip to reach 3k tps?

I think many would assume "not enterprise" or "not datacenter grade" when someone says "Standard GPUs", but maybe that specific phrase have a specific meaning I'm not familiar with.

Edit: I just tried a 4B model on a RTX Pro 6000, getting ~500 tok/s with llama.cpp not even trying to optimize or change anything, just default settings. I'm sure with vLLM it'd be a lot faster already, still before manually tuning configs. I wouldn't call that card "Standard GPU" either FWIW, but it makes the claimed performance numbers feel not as exciting, especially given the hardware they were using.

I expected a 4090, maybe 2. I did not expect 8xH200 for a 2B model.

Great points, let me clarify:

- model size: 2B is just for this preview (it was faster to implement), our article explains how we expect to support large frontier MoE at 1,000 to 5,000 tokens/s

- reaching 500 tok/s, or even up to ~1,000 tok/s, on a consumer GPU card is possible with existing inference engines like vLLM. But there is a ceiling.

The hard part comes we you try to be faster than that: these frameworks won't scale higher just by adding GPUs or using faster GPUs. There is a "glass ceiling" due to microseconds lost everywhere in the stack (grid syncs, inter-GPU comms, kernel launches, CPU sampling, etc.).

All our work at Kog is about removing these bottlenecks.

		That doesn't clarify anything lol. It's a bit click baity.

Did the article headline not say Standard GPU?

so what would be the above-standard GPUs then that they are excluding? Cerebras is not GPU
