WaveSpeedImage-to-video generation with LoRA support
LTX-2 19b is a video generation model developed by Lightricks and released in January 2026. It features 19 billion parameters and is designed to generate videos from text prompts or source images, with support for LoRA (Low-Rank Adaptation) weights to customize output style or subject. The model is served through Wavespeed on MindStudio and accepts inputs including an image URL, resolution, duration, aspect ratio, and a seed value for reproducibility.
LTX-2 19b is suited for workflows that require controlled video generation, particularly when a source image is used as a starting frame or visual reference. LoRA support allows users to apply fine-tuned adaptations without retraining the full model, making it practical for style-consistent or character-consistent video outputs. Pricing ranges from $0.075 to $0.60 per video depending on configuration, and the model is available directly within MindStudio without requiring separate API credentials.
What LTX-2 19b supports
Image-to-Video
Generates video output using a source image as the starting reference frame, accepting an image URL as a direct input parameter.
LoRA Support
Accepts LoRA (Low-Rank Adaptation) weights as an input, enabling style or subject customization without full model retraining.
Resolution Control
Allows users to select output resolution via a dropdown input, giving control over video quality and file size.
Aspect Ratio Selection
Supports multiple aspect ratios selectable via a toggle group input, accommodating landscape, portrait, and square video formats.
Duration Control
Accepts a numeric duration input so users can specify the length of the generated video clip.
Seed-Based Reproducibility
Supports a seed input parameter, allowing users to reproduce identical video outputs from the same prompt and settings.
