Imagen2 is the most advanced text to image diffusion technology product developed by Google DeepMind, which can generate high-quality, realistic images that are closely aligned with the user's text prompts. This technology utilizes the natural distribution of its training data to generate more realistic images, rather than using pre-set styles. Developers and Cloud customers can experience the powerful features of Imagen2 through the Imagen API on Google Cloud Vertex AI. The Google Arts and Culture team has also deployed Imagen2 technology in their "Cultural Icons" experiment, allowing users to explore, learn, and test their cultural knowledge with the help of Google AI.

The improvements of Imagen2 include：

1、Improved Image Subtitle Understanding: Imagen2 creates higher quality and more accurate images by adding more descriptions to the images and subtitles in the training dataset to better match user prompts. These enhanced image subtitle pairings help Imagen2 better understand the relationship between images and text, enhancing its understanding of context and subtle differences.

2、More realistic image generation: The Imagen2 dataset and model advancements have made improvements in many areas where text to image tools often struggle, including realistically rendering hands and faces, as well as keeping images free from visual artifacts.

3、Smooth style conditions: Imagen2's diffusion based technology provides a high degree of flexibility, making it easier to control and adjust image styles. By combining citation style images and text prompts, Imagen2 can generate new images that follow the same style.

4、Advanced internal and external painting techniques: Imagen2 also enables image editing functions such as' internal painting 'and' external painting '. By providing reference images and image masks, users can directly generate new content in the original image or extend the original image beyond its boundaries.

Imagen2 has established strong protective measures during the design and development phase to help mitigate the risks and challenges that its text to image generation technology may bring. Imagen2 integrates the advanced toolkit SynthID for watermarking and recognizing AI generated content, allowing whitelisted Google Cloud customers to directly add imperceptible digital watermarks to the pixels of the image without affecting image quality. Before releasing features to users, we conduct rigorous security testing to minimize the risk of harm.
