[Strengths] It supports interactive precise editing: edit locations can be specified via coordinates, selection boxes, or arrows described in the prompt, with strong element-level control and subject consistency. [Best For] Highly recommended for: precise local retouching, adding/removing/replacing objects at exact positions, style transfer of a single photo, and professional post-editing workflows. [Limitations] Do NOT use this model for text-to-image generation (an input image is required) or for blending multiple reference images; it accepts exactly one input image and outputs exactly one image (no batch or streaming). [Routing] For 2-10 reference images use Seedream 5.0 Pro Multi-Reference; for pure text-to-image use Seedream 5.0 Pro; choose Seedream 5.0 Lite Edit when batch outputs or more than 10 input images are required. ## OpenAPI ````yaml /model-api/bytedance/bytedance-i2i.json post /bytedance/seedream-5.0-pro-edit openapi: 3.1.0 info: description: The image-to-image models API from ByteDance. version: 1.0.0 contact: name: Modellix Support email: support@modellix.ai title: ByteDance Image-to-Image Models API servers: - url: https://api.modellix.ai/api/v1 description: The image-to-image models API from ByteDance. security: - bearerAuth: [] paths: /bytedance/seedream-5.0-pro-edit: post: summary: Seedream 5.0 Pro Edit description: >- [Core Function] Seedream 5.0 Pro Edit is a professional-grade single-image editing (I2I) model.
