Explore Decart’s AI models for video and image transformation

Decart offers state-of-the-art AI models for realtime and batch video transformation, lip synchronization, and image editing. Our models are optimized for creative applications, delivering professional-quality results with minimal latency.

Lucy 2.5 is the latest editing model for realtime and video — text prompts, reference images, or both. Get started →

Realtime models

Realtime models process live video and audio with low latency. They run continuously as long as the connection is open.

Model	ID	Resolution	Use Case
Lucy 2.5	lucy-2.5	720p	Video editing (latest)
Lucy VTON 3	lucy-vton-3	720p	Virtual try-on (latest)
Lucy Restyle 2	lucy-restyle-2	720p	Video restyling
Oasis 3 Preview	oasis-3-preview	768×512	Realtime world model / driving simulator

Oasis 3 Preview is a realtime, promptable world model — you set a scene and drive it with actions, and it generates the next camera frames. It uses the dedicated Python gRPC SDK decart-oasis rather than the @decartai/sdk realtime SDKs. Get started →

Previous generation models

Model	ID	Resolution	Use Case
Lucy 2.1	lucy-2.1	720p	Video editing
Lucy VTON 2	lucy-vton-2	720p	Virtual try-on

Video models

Video models process pre-recorded video asynchronously. Submit a job, poll for completion, then download the result.

Model	ID	Resolution	Use Case
Lucy 2.5	lucy-2.5	720p	Video editing (latest)
Lucy VTON 3	lucy-vton-3	720p	Virtual try-on (latest)
Lucy Restyle 2	lucy-restyle-2	720p	Video restyling

Previous generation models

Model	ID	Resolution	Use Case
Lucy 2.1	lucy-2.1	720p	Video editing
Lucy Clip	lucy-clip	720p	Video editing
Lucy VTON 2	lucy-vton-2	720p	Virtual try-on

Image models

Image models edit and transform images.

Model	ID	Resolution	Use Case
Lucy Image 2	lucy-image-2	480p, 720p	Image editing

Latest aliases

Use -latest aliases to always target the newest version of a model family. The server resolves these to the current latest version automatically, so your code stays up to date without changes.

Alias	Type	Currently resolves to
lucy-latest	realtime + video	lucy-2.5
lucy-vton-latest	realtime + video	lucy-vton-3
lucy-restyle-latest	realtime + video	lucy-restyle-2
lucy-clip-latest	video	lucy-clip
lucy-image-latest	image	lucy-image-2

// Always use the latest Lucy model — no code changes needed when new versions ship
const model = models.realtime("lucy-latest");
const result = await client.queue.submitAndPoll({
  model: models.video("lucy-latest"),
  prompt: "Anime style",
  data: videoFile,
});

Technical Specifications

Video Requirements

All video models accept MP4 files with these specifications:

• Format: MP4 (H.264 or VP8 codec)
• Aspect Ratio: 16:9 or 9:16
• File Size: Maximum 200MB

Choosing the Right Model

Decision Matrix

If you need to…	Use this model	Why?
Transform or edit live video on camera	Lucy 2.5 (lucy-2.5)	Character reference images + text editing in one realtime model (latest)
Apply artistic styles to a live stream	Lucy Restyle 2 (lucy-restyle-2)	Full scene restyling in realtime
Transform or edit existing video	Lucy 2.5 (lucy-2.5)	Best quality, fastest speed, unlimited duration, supports prompt + reference image (latest)
Edit or transform an image	Lucy Image 2 (lucy-image-2)	Precise image editing
Simulate a drivable world for RL or robotics	Oasis 3 Preview (oasis-3-preview)	Realtime world model — actions in, generated camera frames out

Quick Start Examples

Lucy 2.5 (realtime)

import { createDecartClient, models } from "@decartai/sdk";

const client = createDecartClient({ apiKey: "your-api-key-here" });
const model = models.realtime("lucy-latest");
const stream = await navigator.mediaDevices.getUserMedia({
  video: { frameRate: model.fps, width: model.width, height: model.height },
});

const realtimeClient = await client.realtime.connect(stream, {
  model,
  onRemoteStream: (s) => { document.getElementById("output").srcObject = s; },
});

// Character transformation
const photo = document.querySelector("input[type=file]").files[0];
await realtimeClient.set({ prompt: "Transform into this character", image: photo, enhance: true });
