ljleb/comfy-mecha

Provides a modular node-based interface for composing complex Stable Diffusion model merges within ComfyUI's workflow system, supporting techniques like weighted sum, TIES merging, and per-block parameter control without requiring intermediate disk saves. Built on the sd-mecha library, it enables memory-efficient in-memory recipe composition and execution through serializable merge recipes that can combine multiple models and LoRAs with fine-grained control. Extensible via custom Python scripts placed in the `mecha_extensions` directory to define additional merge methods.
