SOL-ILv1 🗡️

Checkpoint Merge • SDXL 1.0 Architecture

SOL-ILv1 is a full SDXL 1.0 checkpoint merge combining the illustrative power of Illustrious v2.0 with the versatile foundation of SmoothMix Ultimate. Designed for artists who need sharp, detailed illustrations with stable composition and strong color rendering.

✦ Details

| Property | Value |

|---------------|------------------------------------------------------------------------|

| Architecture | SDXL 1.0 (UNet 9+1+9) |

| Parameters | 3.47B total |

| Precision | FP16 (UNet + Text Encoders) / FP32 (VAE) |

| File Size | ~7.1 GB |

| Text Encoders | CLIP-ViT/L-14 (embedder.0) + OpenCLIP-ViT/bigG (embedder.1) — included |

| VAE | SDXL 4-channel (included, FP32) |

| Merge Method | Weighted Sum |

✦ Merge Recipe

- Base: stabilityai/stable-diffusion-xl-base-1.0

- Blend A: SmoothMix Ultimate

- Blend B: Illustrious v2.0

- Method: Weighted sum merge

✦ Usage

Load directly as a full checkpoint in:

- ComfyUI: CheckpointLoaderSimple → select SOL-ILv1.safetensors

- AUTOMATIC1111: Place in models/Stable-diffusion/, select from dropdown

- Forge: Same as A1111

No need for separate CLIP or VAE — everything is embedded in the checkpoint.

Recommended Settings

- Resolution: 1024×1024, 832×1216, 1216×832

- Sampler: DPM++ 2M Karras / Euler a

- Steps: 25–35

- CFG: 5–8

- VAE: Built-in (no external VAE needed)

⚠️ Known Issue

Layer 11 of CLIP-ViT/L-14 (conditioner.embedders.0.transformer.text_model.encoder.layers.11) contains NaN values — inherited from the original merge. This affects 0.2% of total parameters and does not impact generation quality in practice, as SDXL uses 12 CLIP layers and failure in one sublayer is compensated by the rest of the encoder.
