Yesterday, OpenAI unveiled their latest generative AI creation, Sora, a text-to-video model that produces shockingly vivid 1080p scenes and animations from written descriptions.
Following innovators like Runway and big tech firms like Google and Meta, OpenAI is diving headfirst into synthetic video generation.
Sora Creates Detailed, Coherent Video Scenes
Feed Sora a description or still photo, and it generates high-quality scenes featuring multiple characters, movement, and background details, OpenAI explains. Sora even extends an existing video by filling in missing visual information.
In OpenAI’s words:
“Sora has a deep understanding of language, allowing it to interpret prompts accurately and generate compelling characters expressing vibrant emotions. The model not only grasps what the user requested in the prompt, but also how those things exist physically.”
Sure, that assertion seems bloated. However, Sora’s samples appear remarkably striking compared to other text-to-video algorithms.
For one, Sora produces videos up to 60 seconds long across various styles—far beyond other text-to-video tools. The videos also largely maintain reasonable coherence rather than exhibiting “AI weirdness” with objects behaving oddly.

While impressive, Sora’s videos aren’t flawless simulacra of reality. Some clips featuring humanoid subjects like robots or people walking have an unmistakable cartoonish or video game-esque appearance. This stylization likely stems from the relatively sparse background details in those generative scenes.
Additionally, in the inevitable fashion of AI media, traces of “weirdness” permeate various samples—cars sporadically reversing course or arms awkwardly blending into blankets.
Yet these anomalies appear more seldom and are muted compared to other text-to-video models. All in all, Sora represents a leap forward despite its imperfect mastery of mimicking the actual world.
OpenAI acknowledges that the model isn’t perfect. It writes:
“[Sora] may struggle with accurately simulating the physics of a complex scene, and may not understand specific instances of 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 model may also confuse spatial details of a prompt, for example, mixing up left and right, and may struggle with precise descriptions of events that take place over time, like following a specific camera trajectory.”
Sora Remains a Research Preview, Not Publicly Accessible
OpenAI presents Sora as an initial research preview, divulging little on its training dataset apart from ~10,000 hours of “high-quality” video.
Most importantly, OpenAI isn’t openly releasing Sora given concerns over misuse – a prudent judgment since Sora could easily be exploited for nefarious purposes.
Currently, Sora remains in testing to prevent inappropriate or dangerous content. OpenAI is providing access to select creative professionals for feedback on advancing the model safely. It remains to be seen whether Sora will stimulate creativity or replace human creativity once fully launched.
What Else Should We Know About Sora?
As an exceptionally powerful video generation tool, Sora warrants thoughtful evaluation of its positive and negative impacts if widely deployed.
For example, Sora could help storytellers and filmmakers translate their creative visions into video more easily than ever. But it may also enable the propagation of misinformation and erode public trust if used to spread deceptive videos.
Moreover, Sora represents a massive leap in AI capabilities to interpret and generate coherent video. As such, policymakers should consider appropriate governance so society can benefit from such innovations while mitigating risks.
The public also must grow more discerning in assessing the authenticity of video and audio as AI synthesis technology advances.
Ultimately, Sora’s promise depends greatly on deliberate steps by OpenAI, lawmakers, professionals, and everyday users alike to steer such breakthroughs toward creative empowerment rather than deception or displacement.
