Imagen 2 is Google's most advanced text-to-image diffusion technology, delivering high-quality, photorealistic outputs that are closely aligned and consistent with the user’s prompt. It can generate more lifelike images by using the natural distribution of its training data, instead of adopting a pre-programmed style.
Imagen 2’s powerful text-to-image technology is available for developers and Cloud customers via the Imagen API in Google Cloud Vertex AI.
The Google Arts and Culture team is also deploying our Imagen 2 technology in their Cultural Icons experiment, allowing users to explore, learn and test their cultural knowledge with the help of Google AI.
Improved image-caption understanding
Text-to-image models learn to generate images that match a user’s prompt from details in their training datasets’ images and captions. But the quality of detail and accuracy in these pairings can vary widely for each image and caption.
To help create higher-quality and more accurate images that better align to a user’s prompt, further description was added to image captions in Imagen 2’s training dataset, helping Imagen 2 learn different captioning styles and generalize to better understand a broad range of user prompts.
These enhanced image-caption pairings help Imagen 2 better understand the relationship between images and words — increasing its understanding of context and nuance.
Here are examples of Imagen 2’s prompt understanding:
More realistic image generation
Imagen 2’s dataset and model advances have delivered improvements in many of the areas that text-to-image tools often struggle with, including rendering realistic hands and human faces and keeping images free of distracting visual artifacts.
Fluid style conditioning
Imagen 2’s diffusion-based techniques provide a high degree of flexibility, making it easier to control and adjust the style of an image. By providing reference style images in combination with a text prompt, we can condition Imagen 2 to generate new imagery that follows the same style.
Advanced inpainting and outpainting
Imagen 2 also enables image editing capabilities like ‘inpainting’ and ‘outpainting’. By providing a reference image and an image mask, users can generate new content directly into the original image with a technique called inpainting, or extend the original image beyond its borders with outpainting. This technology is planned for Google Cloud’s Vertex AI in the new year.
