LTX 2.3 AI is a browser-based AI video generator built around the open-source LTX 2.3 model. The live site positions it as a hosted workflow for generating videos from text prompts or images, with synchronized audio, moderation controls, and support for higher-resolution exports.

Key Features

  • Text-to-Video and Image-to-Video: The product navigation and workspace both expose these two core generation modes.
  • Synchronized Audio Generation: The site states that video and audio are generated together instead of requiring a separate sound workflow.
  • Up to 4K Output: LTX 2.3 AI promotes support for 1080p, 2K, and 4K resolution output.
  • Portrait and Landscape Video: The live FAQ and workspace reference both 16:9 and 9:16 formats, including native portrait mode.
  • Configurable Generation Settings: The workspace shows adjustable duration, resolution, aspect ratio, and frame-rate controls.
  • Browser-Based Access: The on-site FAQ explicitly says users do not need a local GPU or local installation.

What the Workspace Includes

The /workspace page is the actual generation interface. It shows a prompt-driven workflow with both text-to-video and image-to-video modes, a fast mode toggle, duration presets from 6 to 20 seconds, resolution options up to 4K, and frame-rate settings including 24, 25, 48, and 50 FPS.

The interface also shows credit-based generation and a creations/history panel, which makes it clear that LTX 2.3 AI is a hosted production workflow rather than a simple static demo.

Pricing and Product Positioning

The /pricing page describes the commercial model as a mix of monthly plans, yearly plans, and one-time credits. The live site also frames paid access around unlocking higher limits and full tool access.

On the homepage and pricing metadata, LTX 2.3 AI also emphasizes input and output moderation, blocking controls, and compliance-focused review. That moderation layer is part of how the hosted product is differentiated from simply downloading the upstream open-source model.

Why Choose LTX 2.3 AI

LTX 2.3 AI is a practical option for creators who want the flexibility of an open-source model without needing to manage local inference, GPUs, or model setup. Its strongest differentiators on the live site are synchronized audio, support for higher-resolution video, browser-based generation, and direct access to configurable video settings in the workspace.

Frequently asked questions

Do I need a GPU to use LTX 2.3 AI?

No. It runs on cloud GPUs in the browser, so no local installation or GPU is required.

What resolutions and aspect ratios does LTX 2.3 AI support?

Output up to 4K at 24, 25, 48, or 50 FPS, in both 16:9 landscape and natively-trained 9:16 portrait.

How long can generated videos be?

Up to 20 seconds per single generation, with a video-extension workflow to chain longer sequences.

Does LTX 2.3 AI generate audio?

Yes. The model synthesizes ambient sound, music, and effects aligned with the visuals in the same pass, with no separate audio tool needed.

Is LTX 2.3 open source?

Yes. The underlying LTX 2.3 model is Apache 2.0 licensed, with weights published on Hugging Face.
