A faster and cheaper Imagen 3 model, for when price or speed are more important than final image quality
Frequently asked questions
What is imagen-3-fast and how does it differ from Imagen 3?
imagen-3-fast is a speed-optimized variant of Google DeepMind's Imagen 3 text-to-image model. It prioritizes faster generation times and lower cost over maximum image fidelity, making it ideal for rapid prototyping and high-volume tasks where turnaround speed matters more than peak image quality.
What aspect ratios does imagen-3-fast support?
imagen-3-fast natively supports five aspect ratios: 1:1 (square), 9:16 (portrait), 16:9 (landscape), 3:4, and 4:3. This makes it versatile for direct use across social media, presentations, web content, and various digital platforms without requiring post-generation cropping or resizing.
Does imagen-3-fast add watermarks to generated images?
Yes. Every image generated by imagen-3-fast includes SynthID, an embedded digital watermark developed by Google DeepMind. The watermark is visually imperceptible to viewers but enables provenance tracking and supports responsible AI use by identifying AI-generated content.
What output formats does imagen-3-fast support?
imagen-3-fast supports two output formats: JPG and PNG. JPG is suited for web-optimized workflows requiring smaller file sizes, while PNG accommodates transparency-ready workflows. This dual-format support gives creators flexibility depending on their platform and production requirements.
Is imagen-3-fast good for text rendering in images?
Yes. imagen-3-fast inherits Imagen 3's improved text rendering capabilities, producing legible and accurate in-image text. It is suitable for use cases like presentations, signage, typographic compositions, and any design work requiring readable text embedded within generated images.
How does imagen-3-fast handle content safety?
imagen-3-fast features a three-tier configurable content safety filtering system. This allows teams and developers to calibrate content moderation levels to match their specific use case, balancing creative freedom with appropriate safeguards for different audiences and deployment contexts.
When should I use imagen-3-fast instead of the full Imagen 3 model?
Choose imagen-3-fast when speed and cost efficiency are priorities over maximum image fidelity. It is the optimal choice for rapid prototyping, iterative creative exploration, high-volume image generation pipelines, and any workflow where fast turnaround and lower per-image cost outweigh the need for the highest possible image quality.
Who created imagen-3-fast and where is it available?
imagen-3-fast was created by Google DeepMind and is available on CRAISEE through the Replicate provider. It is a text-to-image model under the model slug google/imagen-3-fast, designed for developers and creatives needing efficient, scalable AI image generation.
