ltx-2.5-distilled-lora-450-reduced-ceil96

Rank-reduced (fro90_ceil96) distillation LoRA for few-step ("turbo") sampling on GPUs where the full 8.9 GB rank-450 file does not fit next to the model.

Source	pyros-vault/ltx-2.5-distilled-lora-450-reduced
Recipe	fro90_ceil96
Modules	1660
Rank	256 -> 77.6 mean (ceiling 96)
Ceiling-capped modules	69%
Median kept Frobenius energy	0.763
5th percentile / worst	0.532 / 0.451
File size	1.67 TB

Per module the delta B @ A is truncated by factored SVD (QR of both factors + core SVD - the optimal rank-k approximation), singular values kept until 90% Frobenius energy, capped at rank 96, with a small condition safeguard. Same key format as the source, drop-in wherever the original loads. Typical usage: weight ~0.8 with the official 8-step schedule.

Numbers are copied verbatim from ltx-2.5-22b-distilled-lora-450-bf16_fro90_ceil96_report.json (see that file for the per-module breakdown).
