I have an 8-GPU 4090 machine. The total GPU RAM is 192 GB. I want to run the full-scale, non-quantized FP8-weight Deepseek-V3 on it. Is it possible with the Ktransformers?

192GB HBM is not enough to accommodate non quantized Deepseek-V3 model. You can use KTransformers' GPU-CPU hybrid inference. CPU kernel supports Q8_0 quantization which has almost the same accuracy as the original model.
