After the launch and success of ChatGPT, OpenAI decided to release a new tool based on generative artificial intelligence, which could become a flagship product and which promises to win the attention of web users and simplify the task of content creation. It’s about Sora, an AI video generatorrealistic and high quality.
The operation is very similar to that of the now well-known ChatGPT: intuitive and simple. The results returned are far from trivial, but extremely surprising. Let’s discover the technology that makes the existence and effectiveness of Sora possible, how it can be used and the advantages it guarantees.
Sora, the technology behind it
Sora is a generative artificial intelligence tool, based on a leading architecture that enables powerful and highly effective modeling. In particular, the transformer model is exploited, based on neural networks and capable of analyzing and understanding textual commands. Is able to pay attention to various elements of a text to provide, at the end of the process, content that responds correctly and consistently to the request received from the user and that meets his needs and desires.
It has, therefore, a deep understanding of language and is able to correctly interpret what is asked of him.
Sora is based on research carried out in the past to develop DALL-E and ChatGPT, for this reason it is able to faithfully and precisely follow the instructions provided by the user via prompts
The transformer architecture works in combination with diffusion models, which start from the creation of a random image until creating a final one that responds pertinently to the prompt received. What is achieved and what is made possible is generating high quality videoswith a good resolution and consistent with what the user requests.
Sora it is a text-to-video modelwhich has been trained to be able to simulate movement and everything present in the physical world in order to obtain realistic results.
How Sora works and what it can do
Sora starts from a text command. The user clearly describes the video he wants to obtain and Sora creates it in the most faithful way possible, decoding the prompt and trying to correctly interpret what was requested of him.
At the moment Sora can only generate short videos, no longer than one minute, ed it is available, in the initial phase, only to a small number of users. In particular, it involves a team that must grasp the critical issues, difficulties, irrelevant responses and risks and dangers, and a small group made up of carefully selected artists, designers, directors and creators whose task is to give back feedback on Sora and how this can be useful for all professionals working with creativity.
Sora can generate complex scenes, which involve multiple characters and movements of different types. The contents produced are very detailed and refer not only to what the user specifically requests through the prompt, but also to everything that really exists in the real world. This makes them realistic and highly satisfying.
The model is capable of also work on existing videosadding missing frames, extending their duration or improving their quality.
The tool is, at the moment, not yet perfect and this entails limitations and the possibility of generating videos that contain errors. The greatest difficulties come from the reproduction of some movements in complex scenes, in which there are many subjects, and in cause-effect relationships. For example, the protagonist of the video may eat from a plate, but the food will not decrease. These are details that the developers want to make perfect and on which they will continue to work with dedication.
Sora by OpenAI, safety comes first
OpenAI is extremely aware of the importance of make based products on artificial intelligence safe and, for this reason, it intends to carry out numerous tests and take all necessary measures before Sora becomes available to all web users.
What OpenAI wants to avoid is to encourage misinformation, create content that is based on prejudice or that incites hatred, violence and discrimination. Despite the attention paid during training, in fact, the system may have learned contradictions or incorrect and misleading notions.
Sora will be refined before the official release to all web users in order to guarantee the use of a safe and effective model
It is also important that it is possible to understand when a video is generated with Sora or with other generative artificial intelligence models. For users it will be it is impossible to insert prompts that violate the rules of usesuch as those that require you to generate characters that resemble real, famous people or scenes of violence.
OpenAI can rely on the safety systems already developed for other products released on the market, in particular ChatGPT, which is receiving great appreciation from the public and which is used in an ever-increasing number of areas.
