# 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). --- ## ⭐ Render-verified correct setup (read this FIRST — 2026-06-19) > The GGUF-UNet + `DualCLIPLoader` + `gemma_3_12B_it_fp4_mixed` path documented later > in this skill (the Aitrepreneur installer path) **produces soft/mushy video with > inaccurate faces and eyes.** It runs, but it is NOT the quality path.
