LTX Pro

LTX 2.3 Pro is the premium generation model within the LTX 2.3 ecosystem. It is designed for scenarios where output quality and reliability are more important than maximum generation speed.

Compared with the Fast variant, LTX Pro focuses on higher visual fidelity, improved motion consistency and stronger results for final video outputs. It is intended for creators and teams who need more refined generations for professional use cases such as filmmaking, advertising, product visualization or advanced creative workflows.

The model supports modern AI video generation capabilities including Text-to-Video and Image-to-Video, allowing users to create videos from written descriptions or animate existing visual references.

LTX 2.3 Pro is also the required model for several advanced generation and editing capabilities, including audio-to-video, retake and video extension workflows.

The LTX 2.3 model family includes different variants because different users have different priorities. Choosing between LTX Pro and LTX Fast depends mainly on whether the goal is exploration or production.

LTX 2.3 Fast is optimized for speed and lower-cost experimentation. It is useful when users need to generate many variations quickly, test ideas or build storyboards.

LTX 2.3 Pro prioritizes:

• higher visual fidelity
• better motion stability
• improved detail preservation
• professional-quality final renders
• support for advanced generation endpoints

A common workflow is to use Fast for early creative exploration and switch to Pro when producing the final version. This approach allows creators to combine efficient experimentation with high-quality output.

LTX 2.3 Pro supports a broad range of AI video generation scenarios and provides the quality level expected for advanced creative applications.

Core capabilities include:

• Text-to-Video generation – creating complete video sequences from natural language prompts.
• Image-to-Video generation – animating static images while maintaining the identity and visual structure of the source material.
• Audio-to-Video generation – generating video content based on audio input.
• Video Extension – extending existing videos by generating additional frames.
• Retake workflows – modifying specific parts of generated videos through AI-based editing.

These capabilities make LTX Pro suitable not only for creating new content but also for refining and expanding existing video material.

LTX 2.3 Pro is available through the official LTX API, where developers and creators can integrate AI video generation directly into applications and workflows.

The API supports generation through standard requests and provides access to capabilities such as text-to-video and image-to-video generation. Production workflows can use asynchronous generation methods designed for larger workloads.

For users who do not want to manage GPUs, drivers or local model deployment, API-based generation provides a simpler way to access LTX Pro capabilities.

The model is also part of the broader LTX ecosystem, which includes open-source model resources and tools for users interested in deeper experimentation and local workflows.

The LTX ecosystem includes open-source model resources with publicly available weights, while the LTX API provides a managed way to access generation capabilities without local infrastructure.

This creates two different approaches:

• Hosted generation through API – suitable for creators, developers and businesses that need reliable access without managing hardware.
• Open model workflows – suitable for researchers and advanced users who want deeper technical control and experimentation possibilities.

The exact workflow depends on the user's technical requirements, available hardware and desired level of customization.

Users interested in model customization, local execution and deeper technical workflows can explore related resources covering open models, customization and hardware requirements.

LTX Pro is best suited for users who need consistent and high-quality AI video generation.

Typical users include:

• filmmakers creating visual concepts or production assets
• advertisers developing commercial content
• designers creating product visualizations
• developers building AI-powered applications
• researchers exploring advanced video generation workflows

For simple experimentation and rapid idea testing, LTX Fast may be more efficient. For final outputs, complex workflows and advanced generation capabilities, LTX Pro provides the stronger option.
