The clip is sleek. It shows a dressed woman. She struts through a neon-lit city at night. At first glance, it appears to be footage for a car commercial or music video. Yet, this video wasn’t captured by any camera. The woman, the city street, the pedestrians – the whole scene is fake. OpenAI’s new powerful text-to-video AI system, called Sora, made it.
Sora is a big advance in AI. It can turn written descriptions into photorealistic videos. You can give Sora a text prompt or image. From there, it can make video clips up to 60 seconds long in minutes. The clips look lifelike. The technology is futuristic. It is the latest innovation from the AI research company. The company is behind DALL-E and ChatGPT.
OpenAI has not yet released Sora to the public. But, it has showcased her skills through sample videos online. The results are realistic yet synthetic. They have stunned AI experts. The experts didn’t expect video generation this good so soon. The rapid progress signals how fast AI’s abilities are growing. Massive investments fuel them while also raising escalating societal concerns.
Sora and similar AI video tools threaten to disrupt creative industries. They enable anyone to make slick video content at a meager cost. Even more, the tech can spread disinformation. It can distort reality at a huge scale with AI-generated misinformation videos. These videos are indistinguishable from reality.
What Sora Can Create
Sora can make very realistic videos up to 60 seconds long. But, it is not a big advance in machine learning methods. Experts say the algorithm is much like existing ones. They are for AI video synthesis.
“Their algorithm is almost identical to existing methods. “They scaled it up to bigger data and models,” says Jeong Joon Park. He is an AI researcher at the University of Michigan. Ruslan Salakhutdinov of Carnegie Mellon agrees. He calls Sora “not novel.” Instead, it is “a brute-force approach” done through massive computation.
At its core, Sora is a large diffusion model. It trains to connect text descriptions with video frames. Like OpenAI’s ChatGPT, it uses a transformer architecture. But Sora encodes text into moving video blocks. These blocks forge complete motion sequences. This is unlike mapping language to static pixels.
The developers trained Sora using an iterative process. They removed visual noise from sample videos. This enabled Sora to generate coherent outputs from text prompts. OpenAI has said little about Sora’s training regime. It uses licensed video. It may also use synthetic data from game engines like Unreal.
While the videos showcase Sora’s capabilities, imperfections reveal its artificial nature. The camera moves. Visual details are inconsistent between frames. Objects warp or vanish. These signs show that these are machine-rendered clips, not recordings. Even OpenAI’s curated samples manifest such glitches amidst the realism.
It is an impressive achievement of engineering scale. But, Sora’s core approach does not differ much from prior AI video methods. The results still need fixing. They highlight the challenge of making consistent videos from text alone.
Unveiling Opportunities and Challenges
Sora has imperfections now. But, experts predict the technology will improve. AI image generation has improved too, making flaws harder to detect. Hany Farid is a computer science professor at UC Berkeley. Once he fixes the inconsistencies, he sees potential in Sora’s creativity.
“If AI video advances as image generation has. These flaws will become much less common and harder to spot,” Farid says. He envisions “cool applications.” They will help creators bring their visions to life more using AI video synthesis. The technology could also democratize access to filmmaking and other costly artistic mediums.
“We have dreamed of this,” says Siwei Lyu. He is a computer science professor at the University at Buffalo. He sees it as a dream for AI researchers. “It’s a great achievement.”
But, many artists likely see Sora’s achievements. They see it as theft, not a breakthrough. Sora, like past generative AI models, trained on copyrighted works. It can then reproduce or mimic them while presenting the output as new.
Technology journalist Brian Merchant has already found one Sora clip. It is the same as the existing footage. It shows a vibrant blue bird in stunning detail. It likely came from the same footage that Sora used for training.
Beyond copyright worries. Sora worsens fears about the blurring of fact and fiction. AI can generate videos that look real. It’s hard to tell the truth from fiction made by AI. And, it will only get harder. The implications raise disturbing questions about the future of misinformation.
How Misinformation Spreads
Hany Farid is an expert in detecting deepfakes. He knows well that AI, such as Sora, could be weaponized. These could be used for disinformation and other bad purposes. He warns that past content tools turbocharged online lies. He says Sora may amplify insidious fabrications. These include deepfake porn and political lies.
The core danger is that text-to-video AI removes the need for real source footage. They are usually the starting point for making fake videos. Currently, deepfake videos involve combining AI manipulations with segments of actual footage. But a tool like Sora allows making fake videos from scratch. It does this based only on written descriptions.
Siwei Lyu is a digital forensics researcher. He shares Farid’s concerns. He is especially worried about social media users. They may spread deceptive AI-generated clips online. “For unaware users, AI-generated videos will be very deceptive,” Lyu cautions. He says new forensic methods will be critical. Existing tools have struggled to identify Sora’s output as fake.
OpenAI claims to be using safeguards. These include controlled release, content filtering, and cryptographic metadata. These standards flag AI-generated videos. Yet, both Farid and Lyu agree. Such precautions are not enough to prevent all potential misuse. Bad actors will find ways to get around them.
Generative AI video capabilities are growing stronger and more accessible. The societal threats of convincing misinformation and fake realities are getting bigger. Strong solutions will need more than detection tools. They will need efforts to boost media literacy and stop online disinformation.

A Glimpse into Reality
But, Irene Pasquetto is a misinformation researcher at the University of Maryland. She argues that the threats posed by Sora must be kept in perspective. AI enables disinformation. But, it’s a societal problem. It needs cultural, not technical, fixes.
Pasquetto cautions against overhyping Sora’s risks. Doing so can boost the hype cycle around AI. Companies have reasons to promote their models as very powerful, she notes. This is so even if some see the tech as a threat.
Sora streamlines making fake videos for social media. But, Pasquetto says it doesn’t create a new challenge. Many techniques exist for doctoring online videos. Even sharing real footage with false context can spread conspiracy theories.
Pasquetto advocates for policy. He also advocates for education. He also supports other societal guardrails to combat harmful online content. But, she admits there are no quick fixes. AI video capabilities are growing. Users must remain cautious. The images they see may not show reality as it is.
The core issue extends far beyond any single AI model like Sora. To fight the lies, we need holistic approaches. They must target the human roots of society’s truth crisis. Sora exemplifies this. It will get harder as AI advances.
