Checkpoint // MIDNIGHT_NAI-XL_vPred

MIDNIGHT_NAI-XL_vPred (MDNT_NAI-XL_vPred as the shorthand alternative) is a specialized fine-tuning of the NoobAI-XL (NAI-XL) model, designed to enhance anatomical precision, compositional coherence, and versatile style integration.

Usage Recommendations

// VAE: To achieve optimal results with MIDNIGHT_NAI-XL_vPred, it's essential to load the appropriate Variational Autoencoder (VAE). This model is intentionally provided without a baked-in VAE to offer advanced users greater flexibility. Ensure that the sdxl_vae is correctly loaded to maximize compatibility. You can find the SDXL_VAE at Civitai or Hugging Face. Otherwise, use MDNT_NAI-XL_vPredV1_VAE, which has the VAE already baked in, eliminating the need for separate VAE loaders. No baked-in VAE for V2.

// Sampling Methods: MIDNIGHT_NAI-XL_vPred is optimized specifically for Euler (normal). Use ModelSamplingDiscrete with V-prediction and ZsNR set to true. Other samplers may not provide stable results, and V-prediction models do not support other samplers.

// Custom Workflow for comfyUI users: For an optimized generation process, consider using the custom workflow MIDNIGHT1111_Chasm 2025-02-05, which is also available on huggingface.co. This workflow is tailored to leverage the strengths of the NAI-XL_vPred model, providing a streamlined and efficient image generation pipeline.

Note: The above image is a preview of the MIDNIGHT1111_Chasm workflow.

CFG Scaling: Dynamic CFG Plugin is bypassed as a backup for potential future needs.

Manually adjust CFG scaling within a range of 3-4 for the best balance. For optimal results, a preferred setting of 3.5 is recommended.

Trigger Word Lists

To enhance the model's performance and specificity, the following trigger word lists are included:

- danbooru_artist_webui.csv

- danbooru_character_webui.csv

- e621_artist_webui.csv

- e621_character_webui.csv

These lists provide recognized tags for various artists and characters, facilitating more accurate and tailored image generation. Those can be also found noobai-xl-nai-xl-artist-wildcards-e621danbooru

How to Use

// Method I: reForge

1. Installation: If not already installed, follow the instructions in the reForge repository to set up.

2. Usage: Launch WebUI and use the model as usual.

// Method II: ComfyUI

1. Installation: Follow the setup instructions in the ComfyUI repository.

2. Workflow Sample: Utilize the provided ComfyUI workflow sample for guidance.

// Method III: WebUI

1. Installation: Follow the setup instructions in the WebUI repository.

2. Navigate to the WebUI Directory: Before updating or switching branches, ensure you're inside the stable-diffusion-webui folder

command:

cd stable-diffusion-webui

3. Switch to the Development Branch: If you want to use the latest features from the development branch, run:

command:

git switch dev

git pull

⚠️ Note: The dev branch may contain bugs. If stability is your priority, it's best to stay on the main branch.

4. Update WebUI (Main or Dev Branch): To pull the latest updates while on either branch, run:

command:

git pull

🔄 Restart WebUI after updating to apply changes.

5. Configuration: Ensure you're using a stable branch, as the dev branch may contain bugs.
