Sora

OpenAI's text-to-video generation model

Sora transforms text prompts and images into high-definition video clips up to 20 seconds long at 1080p resolution. Built on a diffusion transformer architecture, it's the most capable AI video generator available in a consumer product as of 2026 — and it's included with your ChatGPT subscription.

What is Sora?

Sora is OpenAI's generative video model, officially launched in December 2024 after months of research previews that captivated the internet. Named after the Japanese word for "sky," Sora represents a leap beyond static image generation — it synthesizes entire video scenes with realistic motion, lighting, and physics from nothing more than a text description.

Under the hood, Sora is built on a diffusion transformer architecture — the same family of models that powers DALL-E 3 for images, but extended to work across time as well as space. Rather than generating a single image, Sora learns to denoise sequences of video frames simultaneously, producing smooth, temporally consistent motion that rivals footage captured with real cameras. This architecture allows Sora to understand and simulate complex physical interactions: water rippling around objects, cloth draping naturally, facial expressions tracking across a long take.

Sora can produce videos at resolutions up to 1080p and durations of up to 20 seconds — well beyond the 4–8 second clips that competing tools typically offer. It accepts text prompts, still images, or existing video clips as input, giving creators multiple entry points depending on their workflow. A photographer can animate a portrait; a marketer can extend a product shot into a cinematic moment; a filmmaker can prototype entire scenes before shooting a single frame of real footage.

One of Sora's most distinctive capabilities is Storyboard mode, which lets users plan multi-scene video projects directly in a timeline interface. Instead of stitching together separate single-clip generations, you describe each scene, set its duration, and Sora generates the entire sequence as a coherent piece — dramatically accelerating the production of short-form content, explainer videos, and social media campaigns.

Sora is available exclusively through OpenAI's ChatGPT interface — no separate app or API key required. ChatGPT Plus subscribers ($20/month) get access to Sora with a monthly generation quota, while ChatGPT Pro subscribers ($200/month) unlock higher resolution output and a larger generation allowance. This tight integration means Sora benefits from OpenAI's ongoing safety research and content moderation infrastructure.

Key Features

✍️

Text-to-Video Generation

Describe any scene in natural language and Sora renders it as a video clip. From sweeping landscape cinematics to tight product close-ups, the model interprets style, lighting, camera angle, and motion cues from your prompt with remarkable fidelity.

🖼️

Image-to-Video Animation

Upload any still image — a photograph, illustration, or design mockup — and instruct Sora to bring it to life. Describe the motion you want: a camera pull-back, a character turning to look, leaves blowing in the wind. Sora animates the scene while preserving the original visual style.

📹

Video Extension

Already generated a clip you love but want it to be longer? Sora's video extension feature continues your footage seamlessly — maintaining consistent characters, environments, lighting, and motion physics to create a longer, uninterrupted scene without visible joins.

🎬

Storyboard Mode

Plan and produce multi-scene video projects in a single session. Lay out your scenes on a visual timeline, assign prompts and durations to each segment, and let Sora generate the complete sequence. Ideal for short films, product demos, and social content series.

🔀

Remix & Blend

Feed Sora two existing video clips and prompt it to blend them into a single video that merges elements from both sources. Alternatively, use the remix feature to re-generate an existing clip with a modified prompt — changing the style, setting, or subject while keeping the core motion intact.

🔆

1080p Full HD Output

Pro subscribers get full 1080p resolution video generation — crisp enough for YouTube uploads, social media feeds, and light commercial use. Multiple aspect ratios are supported: 16:9 landscape, 9:16 portrait (ideal for TikTok and Reels), and 1:1 square.

Pricing

Sora is bundled into ChatGPT's existing subscription tiers — there is no standalone Sora subscription. A separate developer API is planned but not yet publicly available. Pricing below is as of April 2026.

Plan	Price	Video Quota	Max Resolution	Key Extras
ChatGPT Plus	$20 / month	50 videos / month	720p	Text-to-video, image-to-video, standard queue priority

Frequently Asked Questions

What is Sora by OpenAI?

Sora is OpenAI's generative video model, launched in December 2024. It uses a diffusion transformer architecture to create realistic videos up to 20 seconds long at resolutions up to 1080p from text descriptions, images, or existing video clips. It is available to ChatGPT Plus and Pro subscribers and supports features like storyboard mode, video remixing, and video extension.

How much does Sora cost?

Sora is included in ChatGPT Plus at $20 per month, which gives subscribers 50 priority video generations per month at up to 720p. ChatGPT Pro at $200 per month provides 500 video generations per month at up to 1080p resolution with faster generation speeds. A standalone Sora API for developers is planned but not yet publicly available as of April 2026.

How long can Sora videos be?

Sora can generate videos up to 20 seconds in length. Plus subscribers receive shorter clips at standard quality, while Pro subscribers can generate the full 20-second clips at 1080p. The Video Extension feature lets you lengthen an existing video by generating additional seconds that seamlessly continue the original footage, maintaining consistent characters and motion physics throughout.

What resolution does Sora support?

Sora supports resolutions up to 1080p Full HD. ChatGPT Plus subscribers are limited to 720p output, while ChatGPT Pro subscribers get access to full 1080p generation. Sora can generate video in various aspect ratios including landscape (16:9), portrait (9:16 for TikTok and Reels), and square (1:1) formats to suit any platform or use case.

What is Sora's Storyboard mode?

Storyboard mode is a feature that lets you plan and create multi-scene video projects directly in Sora's interface. Instead of generating one clip at a time and manually stitching them together, you lay out a sequence of scenes with different prompts, durations, and timing — similar to a video timeline editor. Sora then generates each scene and assembles them into a coherent video narrative, making it far faster to produce longer-form structured content.

Can Sora generate video from images?

Yes. Sora's image-to-video feature lets you upload a still image and animate it based on a text prompt. You can describe camera movements, character actions, environmental effects (rain, wind, lighting changes), or any motion you want to apply to the scene. This is especially useful for bringing existing artwork, product photography, or design mockups to life without reshooting original footage.

How does Sora compare to Runway and Pika?

Sora stands out for its longer clip duration (up to 20 seconds vs. 4–10 seconds for most competitors), higher resolution ceiling (1080p), and storyboard mode for multi-scene projects. Runway Gen-3 Alpha excels at video editing workflows and has more mature professional tools like motion brush and inpainting. Pika is easier to use for quick social media clips and has a more accessible free tier. Kling AI from Kuaishou offers strong motion realism and competitive pricing for international creators. The best choice depends on your workflow, budget, and whether you prioritize raw generation quality or editing flexibility.
