LTX-2 Microscope

48-Layers Latent Previewer for Lightricks LTX-2 Video Transformer.

[!CAUTION] For now, this project is not compatible to the Node 2.0 (UI) of ComfyUI.

Description

LTX-2 Microscope is a technical diagnostic tool for ComfyUI designed to visualize the internal latent states across all 48 layers of the LTX-2 transformer model during the sampling process. It provides a real-time 8x6 grid overlay to analyze how noise transforms into signal through each layer of the architecture.

Features

  • View Modes: Supports conditioning, unconditioning, and differential visualization.
  • Normalization: Dynamic range remapping via none, min_max, z_score, or percentile modes.
  • Colormaps: Integrated support for 11 perceptual colormaps (Cividis, Inferno, Viridis, Magma, etc.).
  • Animation Control:
    • Realtime: Automated looping playback with FPS control and freeze toggle.
    • Frame-by-Frame: Manual navigation slider for precise temporal latent analysis.

Installation

No external dependencies required. This extension uses native ComfyUI and Python libraries.

  1. Navigate to ComfyUI/custom_nodes.
  2. Clone the repository:
git clone https://github.com/dorpxam/ComfyUI-LTX2-Microscope
  1. Restart ComfyUI.

Usage

The node can be inserted anywhere in the workflow where a MODEL link is available.

  1. Connect the model input/output.
  2. The UI will automatically synchronize with the LTX-2 sampling process.
  3. Use the RESET button to clear the local buffer and return to the idle state.
