ComfyUI-oshtz-nodes

Custom nodes for ComfyUI created for some of my workflows.

LLM All-in-One Node

• Support for multiple LLMs:
  • OpenAI GPT models
  • Anthropic Claude models
  • AWS Bedrock integration
• Image-to-text capabilities with compatible models
• Adjustable parameters for temperature and token limits
• Multi-line prompt support

String Splitter Node

• Split a single input string into up to 10 separate outputs
• Configurable separator (default: comma)
• Perfect for:
  • Parsing comma-separated values
  • Breaking down prompt lists
