- alibaba/qwen-image-3.0-pro-edit: [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 (widthheight), 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 512512 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.
- alibaba/qwen-image-3.0: [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 (widthheight), 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 512512 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.
- alibaba/qwen-image-3.0-edit: [Core Function] Qwen Image 3.0 Edit is the standard image-to-image editing model for instruction-based edits and multi-image fusion.

[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 512512 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.
- google/nano-banana-2: [Core Function] Nano Banana 2 (Gemini 3.1 Flash Image) is an extremely fast text-to-image model. [Strengths] It is optimized for high-speed, high-volume visual generation, creative prompting, and rapid stylistic experimentation. [Best For] Highly recommended for: rapid creative iteration, generating large batches of images quickly, and artistic/stylized graphics.

[Limitations] It lacks the real-time web search and advanced reasoning capabilities of the 5.0 Lite model. [Routing] Use this model when the priority is absolute visual fidelity, resolution (4K), and consistency without the need for real-time search.
- xai/grok-imagine-image-quality: [Core Function] Grok Imagine Image (Quality) is xAI’s high-fidelity text-to-image generation model. [Strengths] It excels at producing richly detailed, high-quality images from a text prompt, with flexible aspect ratios and an optional 2K resolution. [Best For] Highly recommended for: detailed concept art, marketing visuals, and any scenario where image quality is prioritized over generation speed. [Limitations] Do NOT use this model when latency is critical, as generation is slower than the standard model. [Routing] Use this model by default when the user emphasizes quality or detail. For faster, lighter generation use Grok Imagine Image (standard).
- openai/gpt-image-2: [Core Function] GPT Image 2 is a state-of-the-art text-to-image generation model. [Strengths] It excels at generating highly detailed, photorealistic images from text descriptions, with native support for ultra-high resolutions including 2K and 4K (up to 3840x2160). [Best For] Highly recommended for: cinematic landscapes, detailed character portraits, high-end commercial concept art, and any scenario requiring maximum resolution and visual fidelity. [Limitations] Do NOT use this model if you need a transparent background (e.g., for icons or UI assets), as it does not support the
background: transparentparameter. [Routing] Use this model by default for all high-quality image generation requests. If the user explicitly asks for an image with a transparent background, route to GPT Image 1.5 instead. - microsoft/mai-image-2.5: [Core Function] MAI Image 2.5 is Microsoft’s flagship text-to-image generation model. [Strengths] It excels at producing high-quality, detailed images from a text prompt with precise control over output dimensions.

[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.
- openai/gpt-image-1.5: [Core Function] GPT Image 1.5 is a versatile text-to-image generation model. [Strengths] It balances solid visual performance with crucial utility features, notably its native support for generating images with transparent backgrounds. [Best For] Highly recommended for: creating UI icons, standalone logos, game assets, and any graphic design elements that require a transparent background. [Limitations] Do NOT use this model if you need 2K or 4K resolution. Its maximum supported resolution is 1536x1024. [Routing] Choose this model specifically when the user asks for ‘transparent background’, ‘no background’, or ‘PNG icon’. For standard, high-fidelity, or 4K image generation, use GPT Image 2 instead.
