ComfyUI-oshtz-nodes

Custom nodes for ComfyUI created for practical prompt, LoRA, image API, and utility workflows.

Nodes

LLM All-in-One

Easy GPT, Claude, and OpenRouter integration in ComfyUI:

  • OpenAI, Anthropic, and OpenRouter providers
  • Live OpenRouter model list fetched through the node backend
  • Image-to-text capabilities for vision-capable models
  • API keys via widget inputs or environment variables: OPENAI_API_KEY, ANTHROPIC_API_KEY, OPENROUTER_API_KEY

LoRA Switcher (Dynamic)

Dynamic LoRA selection powered by a single configurable node:

  • Drive LoRA choice via API-friendly widget data
  • Unlimited rows with custom strengths managed from the UI
  • Keeps workflows simpler than juggling fixed 10/20/40 variants

GPT Image 1 (Direct API)

Generate or edit images through OpenAI's image API:

  • Text-to-image generation
  • Optional image and mask inputs for edits
  • Quality, size, moderation, and transparent background options
  • Environment variable fallback via OPENAI_API_KEY

Easy Aspect Ratio

Select common image ratios and output ratio text, width, and height.

String Splitter

Split text into multiple outputs:

  • Up to 10 separate outputs
  • Customizable separator
