This AI Research Proposes a Fully Automated Solution for Consistent Character Generation with the Sole Input being a Text Prompt
This study addresses the problem of text-to-image generative models’ inability to consistently generate images. They propose a novel approach to generating consistent portrayals of characters in different circumstances based on a text prompt. The researchers use a clustering technique to extract a representation that captures common traits among images and repeatedly refine the generated model…

Effective altruism, long-termism, and politics in OpenAI
OpenAI, initially a non-profit, shifted to a for-profit structure in 2019, straying from its effective altruism mission. Effective altruism seeks to maximize positive impacts while long-termism focuses on reducing existential risks. OpenAI’s commercial expansion created a conflict between altruistic goals and practical business needs, leading to a clash of ideologies within the company. The recent…
