Introduction
Learn how to generate high-quality images from text in your app. Imagen uses Google’s image generation models via the Gemini API to create detailed, high-quality visuals from text descriptions. It supports aspect ratio control, upscaling, and photorealistic outputs without requiring Vertex AI. This is ideal for building high-quality image generation tools and product visualization experiences.What You Can Build
With Imagen, your app can support:- High-Quality Text-to-Image Generation – Generate detailed and realistic images from prompts.
- Photorealistic Visuals – Create images suitable for product showcases and marketing.
- Product Visualization Tools – Help users visualize ideas, designs, or products.
- Image Upscaling – Enhance resolution and quality of generated images.
- Flexible Aspect Ratios – Generate images tailored for different formats and platforms.
