What do the LTX-Video, CogVideoX and Mochi READMEs state about quantisation, offloading, memory and speed on named GPUs, and where do they say the numbers apply?

CogVideoX has the most explicit table: SAT BF16 76GB (1.5-5B), diffusers BF16 from 10GB, INT8 (torchao) from 7GB; 2B diffusers FP16 from 4GB, INT8 3.6GB; 5B diffusers BF16 from 5GB, INT8 4.4GB; speed at 50 steps single A100 about 1000 s for a 5-second 1.5 video and about 90 s (2B) or 180 s (5B) on an A100 for the original 6-second videos; 3x peak memory if optimisations are disabled. LTX-Video lists FP8 checkpoints and an 8-bit community fork claiming 720x480x121 in under a minute on an RTX 4060 (8GB); H100 timings are given for the distilled 13B. Mochi: about 60GB on one GPU, H100 recommended, --cpu_offload and tiled spatial decoding in the example, ComfyUI said to get under 20GB. Curator correction 2026-10-23 (discovery audit record C3-B681-02; sources re-fetched 2026-10-23, excerpts re-located by curator GET): Problem. C3-B133-G48-05 and -06 describe LTX-Video (0.9.x to 0.9.8) licences and memory figures as the LTX state. Correction type: (e) changed since. Conditions. Applies when choosing an LTX checkpoint or reading its terms. Method. The same README now says LTX-2 is the primary home for LTX development; the LTX-2 model card names a different licence (ltx-2-community-license-agreement) and its text repeats a USD 10,000,000 annual-revenue threshold for 'Entities'. The candidates' LTX-Video facts (8n+1 frames, divisible-by-32 sizes, 0.9.5 Open RAIL-M, 0.9.6+ Open Weights Licence 0.X) were checked and are accurate for that repository; they just no longer describe the newest LTX models. Failure modes. Reading the old licence as covering LTX-2 weights. Limitations. LTX-2 licence clauses beyond the revenue threshold were not analysed; frame and memory rules for LTX-2 were not checked. Version and date. Fetched 2026-10-23. Curator qualifications: Verified the CogVideoX table entries and the Mochi statement. The LTX consumer-GPU figure is a fork claim, not comparable, as stated. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
