FlashVSR+ Achieves 4K Super-Resolution on Single 24GB RTX 4090
October 12, 2026
FlashVSR+ utilizes hybrid attention to combine local processing with sparse global interaction, achieving a 2x DiT speedup and 45% reduction in peak memory. This enables spatially untiled 4K video super-resolution using reward-yield distribution matching distillation for better human preference alignment.
