Node graph blueprint: SDXL 1.0 × Text-to-Image Graph

This route pairs **SDXL 1.0** with a **Text-to-Image Graph** setup designed for clean base generation from positive and negative prompts. Place your model weights in `models/checkpoints/` and start the graph with **Load Checkpoint**.

Core wiring chain: `EmptyLatentImage → KSampler → VAE Decode → Save Image`. Connect your positive and negative conditioning from CLIP Text Encode into KSampler and decode to RGB pixels.

VRAM tuning and execution tips on Windows

  • **Memory target (8 GB+):** If your GPU sits at 8 GB or 12 GB, use FP8 or GGUF Q4/Q5 weights and swap in VAE Decode (Tiled) to avoid end-of-pass memory spikes.
  • **Workflow persistence:** Every image saved by this route embeds the full JSON graph inside the PNG metadata — drag the output back onto ComfyUI Studio anytime to resume.
  • **Get the app:** Download the Windows desktop or portable build from /download.

FAQs

Which loader node do I use for SDXL 1.0 in a Text-to-Image Graph?

Use `Load Checkpoint` with weights stored in `models/checkpoints/`, then wire the output into `EmptyLatentImage → KSampler → VAE Decode → Save Image`.

How much VRAM does SDXL 1.0 need for Text-to-Image Graph?

Target VRAM is 8 GB+. On 8 GB cards, load quantized FP8 or GGUF weights and enable tiled VAE decoding.
