This is a ComfyUI custom node pack providing advanced tile-based image upscaling, inpainting, and detail enhancement via a 'Smart Tile 2.0' system. It enables variable-size, object-aware tiling using SAM3/QwenVL3 for automatic detection and per-tile prompt generation, with an interactive canvas editor in the browser for manual control. The pack also includes video generation helpers: LTX-Video first/last frame conditioning, a TeaCache sampler for HunyuanVideo acceleration, and various conditioning/coordinate nodes. The codebase is predominantly a set of ComfyUI node implementations in Python with a significant frontend JavaScript component for the interactive tile editor. While it functions as a library for ComfyUI workflows, its core tile data structures and layout algorithms could be extracted for use in other image processing pipelines. The repository is actively maintained, with example workflows demonstrating real production usage for high-resolution Flux and HunyuanVideo generation.
