Corrected 2026-10-24 - see C3-B981-01; the original statements below are kept for history and are superseded where the correction says so. The numbers are not comparable across systems because they mean different things: Matrix-Game 2.0's 25 FPS is generation speed on one H100 at 352x640; Hunyuan-GameCraft's 25 fps is the video frame rate while its own table lists inference speed of 0.25 FPS (6.6 with distillation) and the text says latency under 5 s per action; LingBot-World 1 claims under 1 s latency at 16 fps; LingBot 2.0 claims 720p at 60 fps without a hardware statement in the text read; Matrix-Game 4.0 takes player input in a game engine and renders low-poly frames, reporting 480p 60 FPS on an RTX 5090 with 112 ms key-press-to-display latency. Memory is explicit only in Matrix-Game 3.0/4.0 (README/report statements) and is stated as absent or emergent in Matrix-Game 2.0 and LingBot-World.

Curator correction 2026-10-24 (discovery C3-B981-01; sources re-fetched 2026-10-24, excerpts re-located by curator GET): C3-B019-W6-06 says Matrix-Game 4.0 'takes player input in a game engine and renders low-poly frames'. The technical report says the game engine produces low-poly proxies and the video model turns them into detailed visuals: 'transforms engine-rendered low-poly proxies into detailed visuals'. The 480p, 60 FPS, RTX 5090, 112 ms figures in the finding are as stated: 'Matrix-Game 4.0 enables 480p, 60 FPS gameplay on a single NVIDIA RTX 5090 with 112 ms of key-press-to-display latency'. So low-poly describes the engine input, not the displayed output frames. Other claims in C3-B019-W6-06 (Matrix-Game 2.0 25 fps on one H100 at 352x640; GameCraft table 0.25 and 6.6 FPS, under 5 s per action; LingBot-World under 1 s at 16 fps; LingBot 2.0 720p at 60 fps) were rechecked against the arXiv PDFs on 2026-10-24 and match.

Curator qualifications: Key figures verified. The GameCraft conflict is semantic: '25 fps' is the output video frame rate (33-frame chunks at 720p), while Table 2's 'Infer Speed (FPS)' measures generation throughput (0.25; 6.6 with PCM). They are two different quantities, which the producer's F3 already separates. It is not an internal contradiction about one quantity. Relabel the GameCraft entry: frame rate of output vs generation throughput; the paper's 'real-time' framing is not supported by its own throughput numbers (6.6 FPS with distillation vs 25 fps output).
