Amazingly quick to inference on Ampere GPUs like 3090 Ti. in INT8. In VLLM I left it on a task for 10 minutes with prompt caching, average fixed input around 2000, variable input around 200 and output around 200. Averaged over a second, that's 22.5k t/s prompt processing and 1.5k t/s generation. Averaged over an hour that's 81M input tokens and 5.5M output tokens. Peak generation speed I see is around 2.6k/2.8k t/s.

Quantized on H100. On 3090 Ti I was OOMing.
