Hy Image 3.5 Preview is Tencent’s image-generation model, available through Tencent Cloud’s TokenHub API. It accepts text and reference images and supports multi-turn editing, so users can refine an image using earlier conversation context. The official API guide documents automatic sizing and output up to 4K when a size is specified. Tencent Cloud describes the model as supporting text-to-image and reference-based image generation; Tencent’s ADP guide also shows it being used in agent workflows for image creation and editing.
