OpenAI Sora: New text-to-video AI model delivers incredible results
Not so long ago, AI videos were reminiscent of bad drug trips. This is changing today at the latest, as OpenAI has presented its Sora text-to-video AI model. The videos created with it, which can be up to 60 seconds long, are quite something.
If you want to know which text input led to the respective result, you can find the individual videos and prompts on the OpenAI website.
Sora not only has a deep understanding of language to interpret the input, but also knowledge of how things behave in the physical world. Nevertheless, the videos are still far from perfect. If you look closely, you will discover the odd mistake.
OpenAI knows this too. The company points out that the physics have weaknesses in complex scenes. Spatial details can lead to confusion - as can temporal sequences such as a tracking shot. OpenAI also points out that it is possible that Sora does not understand certain cases of cause and effect: "For example, a person might bite into a biscuit, but the biscuit might not show a bite mark afterwards."
Technically speaking, Sora is a diffusion model that is able to create entire videos at once or extend an existing one. It is also possible to use a still image as a template instead of text input. So far, Sora is only available to a selected group of testers. It is not yet clear when the AI model will be released to the public and at what price.
