Q & A
What is Sora and how does it generate videos?
-Sora is OpenAI's text-to-video AI model that creates hyper-realistic, highly-detailed videos of about one-minute length based on text prompts. It uses a diffusion model, a type of generative model, to start from random noise and progressively refine the image, analyzing lots of videos to learn object and action identification, and then defining the timeline and adding detail to each frame to ensure continuity and realism.
What issues can be observed in the AI-generated videos by Sora?
-There are flaws and glitches in the AI-generated videos. For example, the model may not follow the prompt closely, there can be imperfections like objects changing colors between frames, and the simulation of hands is particularly challenging due to their complex motion. Additionally, there might be issues like extra fingers appearing or lack of sound synchronization with the mouth movements.
What kind of data was used to train Sora?
-Sora was trained on a mix of publicly available data and licensed data, which could include content from platforms like YouTube, Facebook, Instagram, and Shutterstock. The videos used for training are 720p and 20 seconds long.
How long does it take to generate a video with Sora?
-The time taken to generate a video with Sora can vary depending on the complexity of the prompt, but it could take a few minutes to produce the video.
What are the computing power requirements for generating Sora videos compared to ChatGPT or DALL-E?
-Sora requires significantly more computing power than ChatGPT or DALL-E. While ChatGPT and DALL-E are optimized for public use, Sora is a research output and is much more expensive to run.
When does OpenAI plan to make Sora available to the public?
-OpenAI is aiming to make Sora available to the public eventually, with a hope for release within the year of the interview. However, the exact timing will depend on the resolution of issues related to misinformation, harmful bias, and ensuring the technology's safety and reliability.
What safety and content considerations is OpenAI taking into account for Sora?
-OpenAI is conducting red teaming to test Sora's safety, security, and reliability. They are identifying vulnerabilities and biases, and considering content limitations similar to DALL-E, such as not generating images of public figures. They are also concerned about the potential impact on global elections and other societal issues.
How does OpenAI plan to address the challenge of content provenance with AI-generated videos?
-OpenAI is researching and working on watermarking the videos to help with content provenance. They are trying to figure out how to trust real content versus AI-generated content, and how to distinguish between reality and AI creations. These considerations are part of the reasons why Sora has not been deployed broadly yet.
What is the potential impact of Sora and similar AI tools on the video industry?
-Sora and similar AI tools could significantly impact the video industry by extending creativity and becoming tools for filmmakers and creators. OpenAI aims to involve industry professionals in the development and deployment of these tools, considering the economic implications when people contribute data.
How does Mira Murati view the balance between the potential of AI tools and the safety and societal considerations?
-Mira Murati believes that the balance between profit and safety guardrails is not difficult, but the real challenge lies in addressing the safety questions and societal implications. She emphasizes that these considerations are what keep her up at night, and that while there is amazement about the technology, it's crucial to navigate the path to integrating AI tools into daily reality carefully.
What is the stance of OpenAI on the inclusion of harmful or illicit content in AI-generated videos?
-OpenAI is cautious about the inclusion of harmful or illicit content in AI-generated videos. They are in the discovery mode, figuring out the limitations and how to navigate them. They aim to ensure that the tool provides a level of flexibility for creative purposes while maintaining ethical boundaries.
How does OpenAI address the concerns of testers being exposed to harmful content during the development of AI tools like Sora?
-OpenAI acknowledges the difficulty of this issue. In the early stages, it is part of the red teaming process to consider the exposure to harmful content. When working with contractors, they go further into managing this process, ensuring that people are willing and able to handle such content.
