QuantWM v3 (Harbin Institute of Technology Shenzhen / NUS; not the model authors) reproduces released models with their official repositories on NVIDIA A800 80GB GPUs and reports BF16 end-to-end generation latency of 193.56 s for LingBot-World-v2 and 112.17 s for HY-World 1.5 (Table 7), with the main evaluation at 480p and 720p, 93 frames. That is 0.48 and 0.829 frames/s (own arithmetic), far below real time, but the Table 7 text does not give GPU count, resolution, checkpoint (distilled few-step or not) or step count, so it cannot be set against the authors' real-time statements. At WorldRoamBench's single-H20 Hz the same 93 frames would take about 52.0 s (LingBot-World) and 71.5 s (HY-World 1.5); the ratios 3.73 and 1.57 are unreconciled.

Curator qualifications: QuantWM reproduces released models on A800 with official repos: BF16 end-to-end 193.56 s (LingBot-World-v2) and 112.17 s (HY-World 1.5) for 93 frames.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
