For each of these open interactive world models, what do the papers and READMEs say about the action space, output resolution, frame rate, context or memory, and hardware, and which cells are measured, claimed or absent?

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