We just shipped a new LTX-2 drop focused on one thing: making video generation easier to iterate on without killing VRAM, consistency, or sync.

If you’ve been frustrated by LTX because prompt iteration was slow or outputs felt brittle, this update is aimed directly at that.

Here’s the highlights, the full details are here.

What’s New

Faster prompt iteration (Gemma text encoding nodes)
Why you should care: no more constant VRAM loading and unloading on consumer GPUs.

New ComfyUI nodes let you save and reuse text encodings, or run Gemma encoding through our free API when running LTX locally.

This makes Detailer and iterative flows much faster and less painful.

Independent control over prompt accuracy, stability, and sync (Multimodal Guider)
Why you should care: you can now tune quality without breaking something else.

The new Multimodal Guider lets you control:

• Prompt adherence
• Visual stability over time
• Audio-video synchronization

Each can be tuned independently, per modality. No more choosing between “follows the prompt” and “doesn’t fall apart.”

More practical fine-tuning + faster inference
Why you should care: better behavior on real hardware.

Trainer updates improve memory usage and make fine-tuning more predictable on constrained GPUs.

Inference is also faster for video-to-video by downscaling the reference video before cross-attention, reducing compute cost. (Speedup depend on resolution and clip length.)

We’ve also shipped new ComfyUI nodes and a unified LoRA to support these changes.

What’s Next

This drop isn’t a one-off. The next LTX-2 version is already in progress, focused on:

• Better fine detail and visual fidelity (new VAE)
• Improved consistency to conditioning inputs
• Cleaner, more reliable audio
• Stronger image-to-video behavior
• Better prompt understanding and color handling
