RA2V: LTX-2.3 Video Generation with Automatic LoRA Routing
RA2V is a new LTX-2.3 video workspace for text-to-video and image-to-video generation. It can stay on the base model, select a compatible LoRA from the prompt, or use a specific adapter chosen by the creator.
One model, three routing modes
- Automatic: semantic positive and negative terms rank compatible adapters for the prompt and generation mode.
- No LoRA: run the LTX-2.3 base model directly.
- Specific: choose a selectable adapter and tune its strength.
The current index contains 74 reviewed LTX-2.3 assets from Hugging Face and Civitai. It covers motion, camera control, visual styles, characters, restoration, editing, reference conditioning, and audio workflows. Specialized adapters remain searchable even when their workflow is not available in the generator.
How automatic matching works
Each indexed adapter has explicit positive and negative semantic terms. RA2V scores the prompt against compatible text-to-video or image-to-video adapters. Weak matches fall back to the base model. A recommendation preview exposes the route before generation.
Pricing
RA2V pricing is the current provider cost plus 20%. One credit is $0.01 and the final charge rounds up to a whole credit.
| Route | 6 seconds | 8 seconds | 10 seconds |
|---|---|---|---|
| Base, 1080p with audio | 58 credits | 77 credits | 96 credits |
| LoRA, 16:9 or 9:16 at 24 FPS | 28 credits | 38 credits | 47 credits |
LoRA jobs are priced from generated megapixels, so choosing 25 FPS costs slightly more. Base jobs without generated audio use the lower visual-only provider rate. The generator shows the applicable estimate before submission.
Using Cinemagraph
The first-party Cinemagraph LoRA is useful for living photographs: a locked composition where water, smoke, fabric, foliage, or another isolated element moves. Choose Cinemagraph directly or describe selective motion clearly enough for automatic routing. RA2V applies the recommended 30 steps, guidance 4, conservative strength 1.0, and explicit motion boundaries. The result view extracts the first and final frames for a quick drift and loop-closure check.
API access
The same routing is available through POST /api/ra2v. The catalog and recommendation preview are available through GET /api/ra2v/catalog and POST /api/ra2v/recommend.
