Creative Lab LoRAs — 24 Official Lightricks Adapters for LTX 2.3 & 2.5

  • +New: 9 LTX 2.5 Creative Lab LoRAs released 2026-09-08..15 — Ingredients (reference-sheet control), Clean Plate, Deblur, Decompression, Colorization, Water Simulation, Day-to-Night, Cinemagraph, and Slow Motion Control (I2V speed knob, ships an official ComfyUI workflow). The LTX 2.3 files don't work on 2.5; these are retrained ports
  • +New: 15 LTX 2.3 Creative Lab LoRAs we'd missed (published June–July 2026, each in its own gated repo) — Ingredients, In/Outpainting, Dub-It, Deblur, Decompression, Colorization, Water Simulation, Day-to-Night, Relight (sun direction), Clean Plate, Instant Shave, Cross-Eyed, Pixel Spatial Upscaler ×2 / ×4, Cinemagraph, Foley V2A (video-to-audio)
  • +Each entry lists the trigger word, recommended LoRA strength, trained resolution bucket, and out-of-scope cases taken from the Lightricks model card
  • +Models page: new 'Creative Lab LoRAs' groups for both families; LTX 2.5 setup guide gets a matching section
  • +Update check now scans every Lightricks repo, not just the main LTX-2.3 / LTX-2.5 ones — that's how this batch slipped through

Pruna Fast VAE for LTX 2.3 + Smaller Gemma 4 GGUF Encoders

  • +New: LTX 2.3 Pruna VAE (Kijai, 1.33 GB) — drop-in ComfyUI conversion of Pruna AI's PrunaVAED decoder; ~1.7× faster decode and ~50% lower peak decode VRAM, encoder and latents unchanged. Natively supported in current ComfyUI builds
  • +New: Gemma 4 12B GGUF Q4_K_M (8.41 GB) and Q2_K (5.96 GB) text encoders for LTX 2.5 (elix3r) — 1.1 GB and 3.5 GB smaller than the Q5_K_M that was previously the only GGUF encoder option
  • +LTX 2.5 guides: encoder tables and 16GB recommendations updated for the new quants
  • +Online generator: page copy now reflects LTX 2.5 Fast/Pro alongside LTX 2.3

LTX 2.5 Model Downloads + VRAM Guides

  • +New: LTX 2.5 official transformer, Gemma 4 text encoder, VAEs, LoRA, upscalers, and duration-head patch — all from the gated Lightricks/LTX-2.5 repo
  • +New: Community GGUF quants (Abiray, elix3r) for the only sub-24GB LTX 2.5 path
  • +New: /guide/ltx-2-5-comfyui setup guide and /guide/ltx-2-5-vram-requirements VRAM guide
  • +VRAM Adapter: added an LTX 2.5 / LTX 2.3 family toggle
  • +Note: LTX 2.5's official files need 24GB+ VRAM combined (Gemma 4 encoder alone is 15.37GB+) — 16GB cards need the GGUF path

INT8 convrot Variants for RTX 20xx / 30xx

  • +New: LTX 2.3 Distilled 1.1 INT8 convrot (Kijai, ~21.5 GB) — rotation-based INT8 that runs on Ampere/Turing INT8 tensor cores, where FP8 matmul is unavailable and MXFP8 only gets BF16-fallback speed
  • +New: LTX 2.3 Dev INT8 convrot (Kijai, ~21.5 GB) — same low-VRAM speedup for the dev/quality + LoRA path
2026-06-03
