What is Sora?
Sora is a text-to-video generator that utilizes advanced diffusion models and transformer architectures to create videos based on written descriptions. These videos are generated by starting with noise and progressively refining it over multiple steps. This diffusion process allows the model to produce realistic, coherent video sequences from a wide range of textual inputs.
Building on OpenAI’s prior successes with GPT, DALL·E, and CLIP, Sora introduces a major leap forward by allowing users to create videos from scratch or extend existing ones based on text prompts. Whether generating an entirely new video or animating an image, Sora’s ability to create visually compelling narratives directly from natural language is unprecedented.

Storyboard Prompt
Prompt:
- A vivid animation shows a psychotropic molecule being ingested, depicted as a small, glowing particle entering the mouth. The background is a stylized representation of the human digestive system, with swirling colors suggesting the beginning of a complex journey.
- The molecule travels through the bloodstream, surrounded by red and white blood cells. It’s depicted as a bright, luminescent particle moving swiftly through a network of blood vessels.
- The molecule reaches the blood-brain barrier, depicted as a shimmering wall, and penetrates it, entering the brain. The scene becomes more intricate, with neurons and synapses lighting up as the molecule interacts with them.
Prompt:
- In a warmly lit children’s room, a little boy and girl sit inside a cozy makeshift yurt constructed from plaid blankets and pillows. They are dressed in playful hats and felt boots, surrounded by the soft glow of lamps. The children giggle as they play with a toy reindeer, their eyes sparkling with imagination.
- The children close their eyes tightly, a sense of anticipation in the air.
- As they open their eyes, they transform into adults, standing in front of a modern hotel landscape in Yakutia, surrounded by real yurts and a vast, snowy winter scene.
Observation: While creating the videos using the ChatGPT Plus account took me a lot of time, I see there is a lot of scope for improvement.
How to Access Sora?
Sora can be acceseed via the new website – sora.com. You can use your ChatGPT plans to get access to the model:
- ChatGPT Plus Account: This plan gives you 50 generations per month. These could be related to the number of text-to-video creations or other specific tasks per month.
- OpenAI Pro Account: This offers unlimited generations in slow queue mode, plus 500 faster generations per month. This tier seems to be focused on offering more flexibility, with the option to process tasks faster for a certain number of generations, while other tasks might be queued and processed more slowly.
- Availability: The service won’t be available to the UK and EU at launch, which might be due to legal, regulatory, or data privacy considerations (such as GDPR). This limitation could be lifted in the future as they expand to more regions.
OpenAI Sora Features

These features outline Sora as a powerful but still-imperfect tool for generating creative video content, particularly for non-photorealistic, stylized projects.
Sora’s Technical Foundations
Sora is fundamentally built on the diffusion model, a technique that begins with random noise and iteratively refines it into a coherent video. This process mirrors how traditional image-to-image diffusion models work, but with the added complexity of video sequences.
The key to Sora’s innovation is the use of patch-based representation for both images and videos. Similar to tokens in GPT, videos and images in Sora are broken down into smaller “patches” of data. This enables the model to process large and complex visual data more efficiently, making it capable of generating videos across various durations and resolutions.
Moreover, Sora builds on the recaptioning technique used in DALL·E 3, allowing it to generate highly descriptive captions for its training data. This ability enables the model to closely follow textual prompts, resulting in videos that are faithful to user instructions and more aligned with the input description.
