Yes, if the model fits in its 288 GB of memory — VRAM capacity decides which models load at all, while its 8000 GB/s of bandwidth decides how fast tokens generate. With 24 GB or more it can hold large quantized models such as 70B-class LLMs in reduced precision, and our model pages list exact VRAM fits per model.
