Inputs (59)
| Name | Type | Default | Description |
|---|---|---|---|
| model | MODEL | — | |
| workspace_dir | STRING | A:/MUSUBI/Training/ZImageSpeedCharacterLoraTraining | Workspace folder for cache, output, logs, config, and the managed dynamic dataset. |
| run_name | STRING | ZImageSpeedCharacterLoraTrainingRun | Run name used for logs. |
| output_name | STRING | ZImageSpeedCharacterLoraTraining | LoRA output name used for checkpoints and downstream preview naming. |
| image_count | INT | 41–20 | How many dynamic image inputs and caption fields to show. |
| resolution_width | INT | 102464–4096 | Training bucket width. Pick the resolution preset you want to train at. |
| resolution_height | INT | 102464–4096 | Training bucket height. Pick the resolution preset you want to train at. |
| blocks_to_swap | INT | 00–64 | How many transformer blocks to swap to CPU. 0 is fastest if VRAM allows it. |
| clear_memory_before_text_encoder | BOOLEAN | true | Clears Comfy and CUDA memory before the text encoder cache stage. |
| cache_strategy | COMBO | auto | Cache behavior. auto reuses cache when present, force rebuilds, skip bypasses cache creation. |
| strength_model | FLOAT | 1.00-100–100 | Strength used when applying the newest trained LoRA back onto the returned MODEL. |
| musubi_root | STRING | A:/MUSUBI/musubi-tuner-ltx2 | Root folder of your musubi install. |
| zimage_checkpoint | STRING | A:/MUSUBI/models/zimage/zimage-base.safetensors | Path to the base Z-Image DiT checkpoint. |
| vae | STRING | A:/MUSUBI/models/zimage/vae.safetensors | Path to the Z-Image VAE checkpoint. |
| text_encoder | STRING | A:/MUSUBI/models/qwen3 | Path to the Qwen3 text encoder checkpoint or directory. |
| fp8_base | BOOLEAN | true | Enable fp8 base model weights during Z-Image training. |
| fp8_scaled | BOOLEAN | true | Enable scaled fp8 weights during Z-Image training. Requires fp8_base. |
| fp8_llm | BOOLEAN | false | Loads the text encoder in fp8 mode during caching to reduce VRAM usage. |
| use_32bit_attention | BOOLEAN | false | Use 32-bit precision for attention computations in the Z-Image model. |
