Key Features

Text-to-Video and Image-to-Video: The product navigation and workspace both expose these two core generation modes.
Synchronized Audio Generation: Video and audio are generated together instead of requiring a separate sound workflow.
Up to 4K Output: Support for 1080p, 2K, and 4K resolution output.
Portrait and Landscape Video: Both 16:9 and 9:16 formats, including native portrait mode.
Configurable Generation Settings: Adjustable duration, resolution, aspect ratio, and frame-rate controls.
Browser-Based Access: No local GPU or local installation required.

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. Paid access unlocks 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 differentiates the hosted product 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 managing local inference, GPUs, or model setup. Its strongest differentiators are synchronized audio, higher-resolution video, browser-based generation, and configurable workspace settings — which is what people usually mean when they search LTX 2.3, LTX23, or LTX 2.3 alternative workflows.
