# LTX-2 / LTX-2.3 Video Workflows

## Version naming (read this first)

There is no "LTX 3.2" or "LTX2.3" as separate products. The user's shorthand refers to **Lightricks LTX-2.3**, a point release of the LTX-2 family. The lineage is:

- **LTX-Video** (2024): first text-to-video model from Lightricks.
- **LTX-2 / LTX-V2** (Oct 2025): 19B-class DiT audio-video foundation model. Bundled checkpoint `ltx-2-19b-distilled.safetensors`, Gemma 3 12B text encoder.
- **LTX-2.3** (released ~March 2026): **22B**-parameter DiT update. Rebuilt VAE (sharper textures/faces/hair/text), ~4x larger text connector (text projection) for prompt adherence, native 9:16 portrait, LoRA support, HiFi-GAN vocoder for cleaner synchronized audio, up to 4K@50fps / ~20s clips. Apache 2.0. **Distributed primarily as GGUF UNets** (community quants) plus separate VAE / text-encoder / text-projection files, NOT a single bundled checkpoint like LTX-2.

When the user says "LTX3.2" / "LTX2.3", treat it as **LTX-2.3**. This skill covers both LTX-2 (bundled checkpoint path) and LTX-2.3 (GGUF UNet path).
