Sora: Open AI announced their first text-to-video generator.

Sora Open Ai test-to-video generator

OpenAI has indeed announced a new tool that can generate videos from text prompts. This model, nicknamed Sora (which means “sky” in Japanese), can produce realistic footage up to a minute long that adheres to a user’s instructions on both subject matter and style.

Sora is also capable of creating a video based on a still image or extending existing footage with new material. The company has opened access to Sora to a few researchers and video creators for testing and feedback.

The videos generated by Sora bear a watermark to show they were made by AI. This is a significant advancement in the field of AI, following the success of OpenAI’s previous models like the still image generator Dall-E and the generative AI chatbot ChatGPT.

It’s important to note that other AI companies have also debuted video generation tools, but those models have only been able to produce a few seconds of footage that often bears little relation to their prompts. Sora’s ability to interpret long prompts and create complex scenes sets it apart.

How does Sora work?

Sora is an amazing text-to-video generator created by OpenAI that uses a variety of advanced methods to function. Although the precise internal workings are confidential, here’s a high-level outline:

Strengths

One thing that may set Sora apart is its ability to interpret long prompts including one example that clocked in at 135 words. The sample video OpenAI shared on Thursday demonstrate Sora can create a variety of characters and scenes, from people and animals and fluffy monsters to cityscapes, landscapes, zen gardens and even New York City submerged underwater.

This is thanks in part to OpenAI’s past work with its Dall-E and GPT models. Text-to-image generator Dall-E 3 was released in September. CNET’s Stephen Shankland called it “a big step up from Dall-E 2 from 2022.” (OpenAI’s latest AI model, GPT-4 Turbo, arrived in November.)

In particular, Sora borrows Dall-E 3’s recaptioning technique, which OpenAI says generates “highly descriptive captions for the visual training data.”

“Sora is able to generate complex scenes with multiple characters, specific types of motion and accurate details of the subject and background,” the post said. “The model understands not only what the user has asked for in the prompt, but also how those things exist in the physical world.”

The sample videos OpenAI shared do appear remarkably realistic — except perhaps when a human face appears close up or when sea creatures are swimming. Otherwise, you might be hard-pressed to tell what is real and what isn’t.

The model also can generate video from still images and extend existing videos or fill in missing frames, much like Lumiere can do.

“Sora serves as a foundation for models that can understand and simulate the real world, a capability we believe will be an important milestone for achieving AGI,” the post added.

AGI, or artificial general intelligence, is a more advanced form of AI that’s closer to human-like intelligence and includes the ability to perform a greater range of tasks. Meta and DeepMind have also expressed interest in reaching this benchmark.

Weaknesses

OpenAI conceded Sora has weaknesses, like struggling to accurately depict the physics of a complex scene and to understand cause and effect.

“For example, a person might take a bite out of a cookie, but afterward, the cookie may not have a bite mark,” the post said.

And anyone that still has to make an L with their hands to figure out which one is left can take heart: Sora mixes up left and right too.

OpenAI didn’t share when Sora will be widely available but noted it wants to take “several important safety steps” first. That includes meeting OpenAI’s existing safety standards, which prohibit extreme violence, sexual content, hateful imagery, celebrity likeness and the IP of others.

“Despite extensive research and testing, we cannot predict all of the beneficial ways people will use our technology, nor all the ways people will abuse it,” the post added. “That’s why we believe that learning from real-world use is a critical component of creating and releasing increasingly safe AI systems over time.”

How does Sora compare to Google’s Lumiere?

While Sora and Lumiere are both outstanding contributions to the field of generative AI, they differ in a few key ways:

1. Purpose:

2. Capabilities

3. Realism

4. Previous Work:

5. Feedback and Public Sharing:

In summary, while both models are impressive, Sora’s focus on video generation and its ability to handle longer prompts set it apart from Lumiere’s image-based approach.

How we can use Sora for business?

Leveraging Sora for your business can open up exciting creative possibilities. Here are some ways you can utilize this text-to-video generator for your business:
