OpenAI Sora explained: How it is different from ChatGPT, and who...
OpenAI has recently introduced Sora, an innovative text-to-video generator that is now accessible to the public. Similar to ChatGPT where you can quickly generate text by submitting a prompt, Sora allows you to create videos by providing prompts. However, Sora offers more functionality such as the ability to bring images to life. For example, you can animate old photos by submitting them to Sora, enabling you to see your ancestors in motion.
Distinguishing Sora from GPT Models
Sora operates as a text-to-video AI model, while GPT functions as a Large Language Model. Though they differ, both showcase compatibility with similar inputs. GPT-4, for instance, is multimodal and can process various inputs like text, images, and videos. On the other hand, Sora allows users to generate videos based on text, images, or videos inputs, creating a new output dimension compared to GPT models that solely generate text outputs.
Training and Architecture
OpenAI claims that Sora was trained on videos and images with diverse characteristics, utilizing a Transformer architecture to process space-time patches of video and image latent codes. The distinct approach is evident in the training methods, with Sora employing visual patches instead of tokens to generate outputs. By segmenting videos into patches and compressing them into a lower-dimensional latent space, Sora can produce high-quality videos.
Accessibility and Pricing
As of now, Sora is not available for free, requiring users to subscribe to either the OpenAI Plus or OpenAI Pro subscription. The Plus subscription, priced at ₹2,000 in India, grants 50 video generations per month, while the Pro subscription priced at $200 offers up to 500 fast video generations. It's essential to note that the resolution and speed of video generation may vary based on the subscription plan chosen.
Despite the demand for Sora, OpenAI has temporarily halted new signups to stabilize the influx of users. CEO Sam Altman reassures users that efforts are being made to address the issue promptly, ensuring widespread access to Sora in the future.
