Google Releases "Imagine": An Unprecedented Text-to-Image Model

Google Research has made a groundbreaking advancement in the field of text-to-image models with the introduction of "Imagine." This system, developed by Google's Toronto-Based research team, is a diffusion model that generates images solely from textual input. The quality and adherence to provided text Prompts displayed by "Imagine" are remarkable, representing a significant improvement over prior related models. In recent years, the progress in text-to-image models has been unprecedented, with increasing simplicity in their architecture. The "Imagine" system, for instance, consists of a frozen text encoder and a text-to-image diffusion model. The scalability of the pre-trained text encoder size appears to impact the model's performance more significantly than the expansion of the diffusion model size. Google's research team also emphasizes the importance of a dynamic thresholding diffusion sampler, which effectively utilizes large classifier-free guidance weights. "Imagine" showcases the potential of large pre-trained frozen text encoders and the dynamic thresholding technique to achieve photo-realistic results and improve image-to-text alignment.

The Allen Institute for AI Releases "Unified IO": A General Purpose Model

The Allen Institute for AI has unveiled "Unified IO," an extensive model designed to tackle various visual and linguistic tasks effectively. This multipurpose model encompasses image generation, region captioning, pose estimation, detection, segmentation, and other related tasks. Its power lies in the utilization of encoders and decoders for each modality, mapping them to a unified token vocabulary. With this unified approach, "Unified IO" can seamlessly process image-plus-text-to-image tasks, such as generating images based on segmentation maps and task descriptions. Similarly, it handles image-plus-text-to-text tasks by generating text descriptions for regions of interest in images. This unified language framework enables the model to attain cross-learning capabilities, leveraging the collective data from diverse tasks. The comprehensive coverage and flexibility of "Unified IO" make it a versatile tool for various visual and linguistic applications.

Tsinghua University's "Cog View 2": Improved Text-to-Image Generation

Researchers from Tsinghua University have developed an advanced version of their text-to-image model called "Cog View 2." Building upon its predecessor, "Cog View 1," this model focuses on enhancing performance and image quality. Unlike fully auto-regressive models, "Cog View 2" adopts partially bi-directionality, enabling concurrent image part generation while attending to the entire image Context. By employing local Attention, this approach decouples generation across multiple stages, resulting in improved inference speed. The super-resolution steps in "Cog View 2" exemplify the benefits of parallel generation, allowing the model to Create multiple image parts simultaneously. The researchers provide a detailed paper, "Faster and Better Text-to-Image Generation via Hierarchical Transformers," explaining the enhancements made to the model. The open accessibility of "Cog View 2" and the available Hugging Face demo make it an exciting tool for text-to-image tasks in English and Chinese.

Google Bans Deepfakes on Its Machine Learning Platform

Google recently implemented a ban on the usage of deepfake software on its machine learning platform, Collab. This decision comes in response to the widespread misuse of Collab for generating deepfakes. While the specifics of how Google will enforce this ban remain unclear, the prohibition is outlined in the platform's terms of use. Violating these terms by running deepfake software may lead to repercussions for users. However, monitoring the code executed on the platform presents a significant challenge. It is probable that Google will prevent the sharing of commonly used Collab notebooks associated with deepfake generation. It is essential to distinguish between harmless and malicious uses of deepfake software, as this prohibition could potentially impact legitimate research projects. The level of stringency applied by Google in enforcing the ban remains to be seen, and future Precedent-setting cases will likely Shape the platform's guidelines.

Cosmopolitan's AI Magazine Cover Design with OpenAI's DALL·E

Cosmopolitan magazine recently showcased their innovative approach to cover design using OpenAI's DALL·E model. Although the claim of an "artificially intelligent magazine cover" is somewhat tongue-in-cheek, the collaboration between artists and AI models is an intriguing concept. The video shared by the artist, Karen X. Chang, demonstrates the iterative process involved in creating the final cover. Brainstorming Sessions, refining prompts, and modifying images contribute to the overall design. The cover, featuring a wide-angle shot of a female astronaut walking on Mars with a synthwave vibe, demonstrates the creative possibilities offered by DALL·E. However, it is important to note that the claim of the design process taking only 20 seconds is misleading. While the inference time of DALL·E is rapid, the actual creation of the magazine cover took days, weeks, or even months. This collaboration between artists and AI models serves as a testament to the potential of AI in augmenting creativity.

Tips, Tricks, and Experiments for Interacting with DALL·E

Twitter user @guyparsons, also known as Gee Parsons, has shared a valuable thread containing tips, tricks, games, experiments, and combinations for interacting with OpenAI's DALL·E model.
