[Core Function] Qwen Image 3.0 Edit is the standard image-to-image editing model for instruction-based edits and multi-image fusion. [Strengths] It accepts 1-3 reference images plus an edit instruction, optional negative prompts, free-form output size (width*height), intelligent prompt rewrite (direct mode), and 1-6 outputs while preserving subject identity. [Best For] Background replacement, outfit or style changes, multi-image fusion, and iterative retouching when Pro-tier quality is not required. [Limitations] Do NOT use this for pure text-to-image with no reference images (use Qwen Image 3.0 instead). Keep output total pixels within 512*512 to 2048*2048. prompt_extend_mode only supports direct (agent is T2I-only). [Routing] Route here when the user provides reference image(s) and wants balanced Qwen 3.0 edit quality. Prefer Qwen Image 3.0 Pro Edit for higher quality edits.
[Core Function] Qwen Image 3.0 is Alibaba's standard text-to-image model balancing quality and speed. [Strengths] It supports free-form output size (width*height), optional negative prompts, intelligent prompt rewrite (direct/agent modes), batch generation of 1-6 images, and long structured prompts. [Best For] General creative stills, posters with readable text, product shots, and multi-variant exploration (n up to 6) when Pro-tier photorealism is not required. [Limitations] Do NOT use this if the user needs image editing with reference images (use Qwen Image 3.0 Edit). Keep total pixels within 512*512 to 2048*2048. Very long prompts combined with a long negative_prompt may exceed the model input capacity (about 4.5k tokens total). [Routing] Prefer Qwen Image 3.0 Pro for higher photorealism; use this for balanced quality/speed. If the user provides reference image(s) to edit, route to Qwen Image 3.0 Edit instead.
[Core Function] Qwen Image 3.0 Pro Edit is an image-to-image editing model for instruction-based edits and multi-image fusion. [Strengths] It accepts 1-3 reference images plus an edit instruction, optional negative prompts, free-form output size (width*height), intelligent prompt rewrite, 1-6 outputs while preserving subject identity, and long structured edit instructions. [Best For] Highly recommended for: background replacement, outfit or style changes, multi-image fusion, identity-preserving portrait edits, and iterative creative retouching. [Limitations] Do NOT use this for pure text-to-image with no reference images (use Qwen Image 3.0 Pro instead), native 4K output, or thinking-mode reasoning. Keep output total pixels within 512*512 to 2048*2048; input images should follow supported formats and size guidance. Do NOT combine very long prompts with multiple reference images and a long negative_prompt if the request may exceed the model input capacity (about 4.5k tokens total across text and images). [Routing] Route here when the user provides reference image(s) and wants Qwen 3.0 edit quality. For text-only generation without images, use Qwen Image 3.0 Pro.
[Core Function] Qwen Image 3.0 Pro is Alibaba's latest text-to-image model with strong prompt following and photorealism. [Strengths] It supports free-form output size (width*height), optional negative prompts, intelligent prompt rewrite, batch generation of 1-6 images, and long structured prompts for complex layouts. [Best For] Highly recommended for: photorealistic stills, marketing posters with readable text, detailed scene compositions, multi-panel layouts, product hero shots, and multi-variant creative exploration (n up to 6). [Limitations] Do NOT use this if the user needs native 4K output, thinking-mode reasoning, or image editing with reference images (use Qwen Image 3.0 Pro Edit for edits). Keep total pixels within 512*512 to 2048*2048. Very long prompts combined with a long negative_prompt may exceed the model input capacity (about 4.5k tokens total). [Routing] Prefer this over Qwen Image 2.0 Pro for new Qwen Image text-to-image work. If the user provides reference image(s) to edit, route to Qwen Image 3.0 Pro Edit instead.
[Core Function] Seedream 5.0 Pro Multi-Reference is a professional-grade multi-reference image generation (I2I) model that creates a single image from 2-10 reference images plus a text prompt. [Strengths] It excels at reference consistency, preserving characters, styles, and objects across multiple input images while following complex blending instructions with professional-grade quality. [Best For] Highly recommended for: keeping character or style consistency across references, combining subjects from different images into one scene, placing products into reference scenes, and IP-consistent content creation. [Limitations] Do NOT use this model with fewer than 2 or more than 10 reference images, and do NOT use it for batch generation or streaming; it outputs exactly one image per request. [Routing] For single-image editing use Seedream 5.0 Pro Edit; for text-only generation use Seedream 5.0 Pro; choose Seedream 5.0 Lite Edit when up to 14 reference images or batch outputs are needed.
[Core Function] Seedream 5.0 Pro Edit is a professional-grade single-image editing (I2I) model. [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.
[Core Function] Seedream 5.0 Pro is ByteDance's flagship professional-grade Text-to-Image (T2I) generation model. [Strengths] It delivers top-tier image quality with enhanced precision control over positions and elements, superior prompt adherence, and improved generation consistency for professional scenarios. [Best For] Highly recommended for: professional design assets, high-fidelity photorealistic imagery, precisely controlled compositions, and brand or commercial visuals where quality matters most. [Limitations] Do NOT use this model for batch image generation or streaming output; it generates exactly one image per request and supports up to 2K resolution (no 3K/4K). [Routing] Choose this Pro model when the user emphasizes ultimate quality or precision. Choose Seedream 5.0 Lite when real-time web knowledge, batch generation, or 3K resolution is needed. To edit an existing image use Seedream 5.0 Pro Edit; to blend multiple reference images use Seedream 5.0 Pro Multi-Reference.
[Core Function] Nano Banana 2 Lite Edit (Gemini 3.1 Flash Lite Image) is the lightweight, cost-efficient image editing model of the Nano Banana 2 family; it transforms one or more input images per a text instruction. [Strengths] It performs fast, low-cost instruction-based editing across up to 14 input images. [Best For] Highly recommended for: high-volume edits, quick style transforms, and batch background or attribute changes where cost and throughput matter. [Limitations] Do NOT use this model when you need the highest edit fidelity or richest detail; use Nano Banana 2 Edit or Nano Banana Pro Edit instead. [Routing] Choose the Lite variant for cost- and throughput-sensitive edits; step up to Nano Banana 2 Edit for higher quality.
[Core Function] Nano Banana 2 Lite (Gemini 3.1 Flash Lite Image) is the lightweight, cost-efficient text-to-image model of the Nano Banana 2 family. [Strengths] It generates images even faster and more cheaply than Nano Banana 2, well suited to high-volume creative and stylized output at lower cost. [Best For] Highly recommended for: high-volume batch generation, quick drafts and thumbnails, and cost-sensitive creative iteration. [Limitations] Do NOT use this model when you need maximum detail, high-end photorealism, or the richest quality; use Nano Banana 2 or Nano Banana Pro instead. [Routing] Choose the Lite variant when cost and throughput matter more than peak quality; step up to Nano Banana 2 for richer results.
