This plugin provides image generation capabilities for Dify based on ModelScope API‑Inference, supporting both text‑to‑image and image‑to‑image functionality. With just a ModelScope API Key, users can call a wide range of AIGC models (e.g., Tongyi-MAI/Z-Image-Turbo, MusePublic/489_ckpt_FLUX_1, Qwen/Qwen-Image-2512, etc.) within Dify workflows, and flexibly adjust parameters such as aspect ratio, resolution, sampling steps, guidance scale, random seed, and LoRA models to achieve high‑quality image generation.
