# LTX-2.5-Diffusers

Quantised media packages of [Lightricks/LTX-2.5-Diffusers](https://huggingface.co/Lightricks/LTX-2.5-Diffusers).

## MECHA Forge

MECHA — Model Engineering & Contextual Hearth Assembly

These media packages have been forged and optimized in the MECHA Forge.

## Description

LTX 2.5: text/image-to-video generation. 40 steps, CFG 3.0. Elaborate English prompts.

## Available quantizations

| Quant | Denoiser | Text encoder | VAE |
|---|---|---|---|
| FP8 | FP8 | FP8 | FP8 |
| INT8 | INT8 | INT8 | INT8 |
| FP4 | FP4 | FP4 | FP8 |
| INT4 | INT4 | INT4 | INT8 |

The VAE is shared between formats: FP4 reuses the FP8 file, INT4 reuses the INT8 file.

## Components

In addition to the denoiser, text encoder, and VAE, the package includes:
- audio_vae, connectors, duration_head
- latent_upsampler, temporal_latent_upsampler
- prompt_enhancer, transformer_full
- vocoder, scheduler, processor, tokenizer

## Recommended settings

From the source model card (adjust to taste):

| Parameter | Value |
|---|---|
| Steps | 30 |
| CFG / Guidance scale | 3.0 |
| Resolution | under 720x1280, <=257 frames |
| Notes | Elaborate English prompts; negative prompt supported |

## Example prompts

Caught in the moment (candid, slice of life):

```

candid moment, natural lighting. A sunlit park bench in autumn, falling leaves,
