The first generation open-source model for joint audio-video generation, predecessor to 2.3. It is now mostly used as a comparison baseline or for running old workflows.
Base
Highlights
- 19B, the pioneering work of joint audio-video generation
- Rich companion LoRA and camera-control templates
- Distilled version can produce output in few steps
Scope
- Good for: reproducing old workflows, running community LoRA
- Not for: chasing the latest
Tips
- The community has many camera-control LoRA based on LTX-2
- Old templates may not be compatible with new weights; watch versions
Cautions
- Community license
Parameters
- Distilled version
- Few steps (see template)
- Resolution
- 720p class
- Ecosystem
- Official templates include audio-to-video, depth/edge control, etc.
Deployment
- 16GB conclusion
- Tight; distilled version + fp8 recommended.
- VRAM note
- Slightly smaller than 2.3, but still 20B class.
- Suggested starting point
- New projects should use 2.3/2.5 directly; leave LTX-2 for compatibility with old workflows.
Comparison
The first-generation 19B joint audio-video model, 270k downloads. Compared with 2.3/2.5, it is now mainly a compatibility layer for “running old workflows/LoRA”; there is no reason for new projects to start from it.
