Node graph blueprint: SD 1.5 × Automated Seed Batch Queue

This route pairs **SD 1.5** with a **Automated Seed Batch Queue** setup designed for queuing 20–100 prompt variations overnight on Windows. Place your model weights in `models/checkpoints/` and start the graph with **Load Checkpoint**.

Core wiring chain: `Primitive Seed (increment) → Instant Queue / Batch Count → Save Image with date prefix`. 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 (4 GB–6 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 SD 1.5 in a Automated Seed Batch Queue?

Use `Load Checkpoint` with weights stored in `models/checkpoints/`, then wire the output into `Primitive Seed (increment) → Instant Queue / Batch Count → Save Image with date prefix`.

How much VRAM does SD 1.5 need for Automated Seed Batch Queue?

Target VRAM is 4 GB–6 GB. On 8 GB cards, load quantized FP8 or GGUF weights and enable tiled VAE decoding.
