The model applies a method called quantization-aware distillation (QAD) to the Wan2.1-T2V-1.3B base model, reducing computational precision to speed inference while limiting quality loss. Three variants are available: FastWan-QAD-1.3B (NVFP4 precision, SageAttention3 FP4 backend, 1.8 seconds), FastWan-QAD-1.3B-SA2 (higher quality, SageAttention2++, 2.01 seconds), and FastWan-QAD-FP8-1.3B (FP8 precision, runs on RTX 40 series, 3.4 seconds on an RTX 4090). The fastest variant achieves a 95.6x speedup over the base model.
