Running big models on a single RTX 4090: INT8 weights, FP8 decoder, RAM tiering

AIFlow_ML · x · 2026-10-25

AIFlowML summarizes a practical setup for running large models on a single RTX 4090: INT8 weights and cache, FP8 decoder, each module moved to GPU only during its stage, with 18 latent history frames kept on GPU and the rest archived in system RAM. Key takeaway: budget for RAM, not just VRAM.

Sources included: the model card (see 'Model Assets' for the INT8/LoRA line) is worth reading in full, with code and demo linked in the post — a concrete reference for local video-model deployment on consumer cards.
