Kokon is a free, open‑source desktop application that enables zero‑setup photo editing with Qwen‑Image 2.1 on local GPUs (≥12 GB VRAM). On first launch it detects the GPU and memory, downloads the appropriate GGUF models (Qwen‑Image 2.1 Turbo Q4_K and Qwen3‑VL 8B text encoder, ~12 GB checksummed), and automatically sizes each generation job. The app provides a straightforward photo‑editor interface while handling quantization, offloading, and resolution selection internally.
