# LTX-2.5 Distilled GGUF
|
| 30 |
+
|
| 31 |
+
This repository provides quantized GGUF formats of the distilled transformer from [Lightricks/LTX-2.5](https://huggingface.co/Lightricks/LTX-2.5). These weights are highly optimized for local execution, allowing you to run high-fidelity video and audio generation workflows on hardware with memory constraints while retaining the core visual fidelity of the original base model.
|
| 32 |
+
|
| 33 |
+
## Available Quantizations
|
| 34 |
+
|
| 35 |
+
| File | Size | Description |
|
| 36 |
+
|---|---|---|
|
| 37 |
+
| **LTX-2.5-Distilled-Q3_K_M.gguf** | 11.5 GB | Smallest footprint with the highest quantization loss. Best for strict memory limits. |
|
| 38 |
+
| **LTX-2.5-Distilled-Q4_K_S.gguf** | 13.9 GB | Slightly smaller than Q4_K_M, balancing speed and limited VRAM/RAM. |
|
| 39 |
+
| **LTX-2.5-Distilled-Q4_K_M.gguf** | 15.1 GB | Recommended baseline. Good balance of visual fidelity, motion consistency, and memory footprint. |
|
| 40 |
+
| **LTX-2.5-Distilled-Q5_K_M.gguf** | 16.8 GB | Higher precision, retaining strong prompt adherence with minimal degradation. |
|
| 41 |
+
| **LTX-2.5-Distilled-Q6_K.gguf** | 18.7 GB | Near-unquantized visual quality, very low quantization loss. |
|
| 42 |
+
| **LTX-2.5-Distilled-Q8_0.gguf** | 23.6 GB | Largest quantized footprint, nearly indistinguishable from the original bf16 weights. |
|
| 43 |
+
|
| 44 |
+
## About the Original Model
|
| 45 |
+
|
| 46 |
+
**LTX-2.5** is an open-world model built for local execution and fine-tuning. It specializes in generating synchronized, high-fidelity video and audio from text, image, and video inputs.
|
| 47 |
+
|
| 48 |
+
### Key Features of LTX-2.5
|
| 49 |
+
* **Native Multishot Generation:** Generate connected scenes in a single pass holding character identity, environment, lighting, voice, and visual style across cuts.
|
| 50 |
+
* **Diffusion Fidelity Rendering:** The model dynamically allocates compute based on scene complexity, rendering flawless detail where needed.
|
| 51 |
+
* **Distilled Efficiency:** These GGUF checkpoints are derived from the distilled model, capturing much of the full 22B model's capabilities in a significantly faster, smaller package.
|
| 52 |
+
|
| 53 |
+
## Usage Requirements
|
| 54 |
+
|
| 55 |
+
Ensure your inference engine (such as `llama.cpp` or compatible ComfyUI GGUF loader nodes) supports the LTX-2.5 DiT architecture. Depending on the quantization tier, appropriate system RAM or GPU VRAM size must be allocated to accommodate the file sizes listed above.
|
| 56 |
+
|
| 57 |
+
## License & Limitations
|
| 58 |
+
|
| 59 |
+
These weights fall under the original [LTX-2.x Community License](https://github.com/Lightricks/LTX-2/blob/main/LICENSE.md). Commercial and production use is permitted at no cost for entities under $10M annual revenue.
|
| 60 |
+
|
| 61 |
+
* This model is not intended or able to provide factual information.
|
| 62 |
+
* Prompt following is heavily influenced by prompting style.
|
| 63 |
+
* The model may fail to generate videos that match the prompt perfectly or may generate artifacts in highly complex scenes.
