Imagen 4.0 Fast

[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.
