"## What Imagen 4.0 Ultra Does
Imagen 4.0 Ultra is Google’s highest-quality text-to-image model, optimized for maximum detail and photorealism. It generates the most refined output in the Imagen 4.0 family, ideal when fidelity is the top priority.

Key Features

• Highest-Quality Output: Tuned for maximum detail and photorealistic fidelity.
• Up to 2K Resolution: Select 1K or 2K output via imageSize.
• Batch Output: Generate 1–4 images per request via sampleCount.
• Common Aspect Ratios: Supports 1:1, 3:4, 4:3, 9:16, and 16:9.
• Person Generation Control: Use personGeneration (dont_allow, allow_adult, allow_all) to govern depiction of people.
• Asynchronous Architecture: Uses a ““Create Task → Poll Result”” API workflow for reliable integration.

How to Use Imagen 4.0 Ultra

1. Write a detailed text prompt describing the subject, lighting, mood, and composition.
2. Submit a POST request to the /google/imagen-4.0-ultra-generate-001 endpoint with your prompt and optional sampleCount, aspectRatio, personGeneration, and imageSize.
3. Receive a task_id with a ““pending”” or ““processing”” status.
4. Poll the provided GET endpoint to monitor the task.
5. Once complete, retrieve and download the generated image(s).

Best Use Cases

• Premium Marketing Visuals: Create flagship campaign imagery where detail is paramount.
• Cinematic & Sci-Fi Scenes: Render dramatic, highly detailed environments.
• High-End Portraits: Produce refined portrait imagery with realistic detail.
• Showcase & Hero Assets: Generate standout visuals for key placements.

Tips for Better Results

• Use It When Fidelity Leads: Choose Ultra over standard/Fast when maximum detail and photorealism matter more than speed.
• Write Rich, Cinematic Prompts: Specify lighting, lens, mood, and composition to exploit the model’s detail.
• Generate at 2K: Set imageSize: 2K for the sharpest final output.
• Tune Person Settings: Use personGeneration to match content and safety needs for portraits.
• Mind the Rate Limit: Stay within ~100 requests per minute and up to 4 images per request when batching."

• google/imagen-4.0-fast-generate-001: [Core Function] Imagen 4.0 Fast is a high-speed text-to-image model optimized for rapid visual generation. [Strengths] It offers incredible generation speed (approximately 2.7 seconds) and high cost-effectiveness while maintaining excellent text rendering inside images. [Best For] Highly recommended for rapid prototyping, quick design iteration, high-volume image generation, social media thumbnails, blog hero images, and UI mockups. [Limitations] Do NOT use this model if you require 2K resolution (it does not support the imageSize parameter) or the absolute highest cinematic fidelity and strict prompt alignment. Does not support negative prompts or native image editing. [Routing] Choose this model when the user emphasizes ‘fast’, ‘quick’, ‘rapid’, or needs high-volume, low-latency generation.
• google/imagen-4.0-generate-001: [Core Function] Imagen 4.0 is Google’s flagship professional-grade text-to-image model designed for high-fidelity visual generation. [Strengths] It excels at industry-leading photorealism, exceptional typography/text rendering inside images, and strong prompt adherence, supporting up to 2K resolution and batch generation. [Best For] Highly recommended for general high-quality image generation, marketing assets (posters, product labels, menus, signage), and product photography mockups where readable text is required. [Limitations] Do NOT use this model if you need instant/real-time generation, native image editing (inpainting/outpainting), or negative prompts. It is strictly an image-only output model. [Routing] Use this model by default for high-quality, photorealistic text-to-image requests. If the user emphasizes speed or needs lower cost, route to Imagen 4.0 Fast. If the user demands the absolute highest detail and prompt precision, route to Imagen 4.0 Ultra.
• 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.
• alibaba/wan2.7-image-pro: [Core Function] Wan 2.7 Image Pro is Alibaba’s flagship reasoning-enhanced image generation model. [Strengths] It features built-in chain-of-thought reasoning (Thinking Mode), exceptional prompt accuracy, native 12-language text rendering, and generates ultra-high-resolution 4K images. [Best For] Highly recommended for: print-ready large-format posters, complex logical prompts, and generating images containing specific text/typography. [Limitations] Do NOT use this model if you need to generate batch images rapidly (use Wan 2.7 Image instead) or if you specifically need negative prompts (use Qwen Image 2.0 Pro). [Routing] Use this model by default for high-end, 4K, or text-heavy image generation tasks.
• alibaba/qwen-image-2.0-pro: [Core Function] Qwen Image 2.0 Pro is a professional-grade, highly controllable image generation model. [Strengths] It provides exquisite photorealism, professional infographics generation, supports NEGATIVE prompts, and can generate up to 6 image variants per API call. [Best For] Highly recommended for: workflows requiring strict negative prompt exclusion, batch generation (6 variants), and highly detailed infographics. [Limitations] Does not natively output 4K resolution (max is 2K). Does not have the explicit ‘Thinking Mode’ of Wan 2.7. [Routing] Route to this model specifically when the user provides a ‘negative prompt’ or asks for ‘batch generation of 6 images’.
