LTX-2.5 22B

About

LTX-2.5 22B generates video and synchronized sound together. Create from text, animate one image, guide a transition with opening and closing frames, generate from audio alone, or combine an image with an audio track.

The video-to-video family supports canny, depth, pose, detailer, inpaint, and outpaint workflows. Pose uses a source video for motion plus a still image for the subject's appearance; inpaint uses a mask to identify the region to replace.

Fast, HQ, and Pro currently use the same release-validated official Distilled/Turbo path. Dev checkpoints are not publicly routed until Lightricks publishes an official ComfyUI Dev recipe and Sogni validates it.

Choose an LTX-2.5 workflow

Five public model IDs cover generation and editing. First-and-last-frame video uses the I2V ID with its dedicated template; Fast, HQ, and Pro all route to these release-validated Distilled/Turbo workflows.

Compatibility boundaries

LTX-2.3 remains available as an explicit rollback family. Voice ID-LoRA, the community transition LoRA, and 10Eros remain LTX-2.3-only and are not attached to LTX-2.5 requests.

Pricing

LTX-2.5 22B is included on every Sogni plan — generate credit-free under fair use, alongside 200+ other models. Pay-as-you-go Spark packs are also available for eligible Spark renders.

API

One Sogni API key reaches every model on the Supernet — call LTX-2.5 22B with the exact model id for the variant you want.

import { SogniClient } from '@sogni-ai/sogni-client';

const client = await SogniClient.createInstance({
  appId: crypto.randomUUID(),
  apiKey: process.env.SOGNI_API_KEY,
  network: 'fast',
});

const project = await client.projects.create({
  type: 'video',
  modelId: 'ltx25-22b-int8_t2v_distilled',
  positivePrompt: 'a slothicorn surfing a wave of liquid paint, slow push-in, cinematic',
  numberOfMedia: 1,
  duration: 5,
});

const [url] = await project.waitForCompletion();
console.log(url); // result link — download within 24h
