OpenAI’s Sora launched as the most hyped AI video generator in history. Sora 2 followed in late 2025 with native audio, improved physics, and a dedicated mobile app. Then, on March 24, 2026, OpenAI pulled the plug. The app shut down on April 26, and the API is scheduled to follow on September 24, 2026.
This review covers what Sora delivered, where it fell short, and whether the remaining API access is worth using before the lights go out entirely.
What Is Sora?
Sora is OpenAI’s text-to-video and image-to-video model. The original version debuted in early 2024 as a research preview. Sora 2, launched September 30, 2025, brought a standalone iOS app (Android followed two months later), native audio generation, and significantly better motion realism.
At its peak, Sora had roughly one million active users. By the time OpenAI announced the shutdown, that number had dropped below 500,000. Lifetime revenue from in-app purchases totaled an estimated $2.1 million — a fraction of the roughly $1 million per day the platform cost to run.
Pricing at a Glance
Since the Sora app is already offline, the only remaining access path is the API (available until September 24, 2026). For reference, here is how pricing worked across both subscription and API tiers.
ChatGPT Subscription Access (Discontinued April 26, 2026)
| Plan | Monthly Cost | Video Access |
|---|---|---|
| Free | $0 | Removed January 2026 |
| ChatGPT Plus | $20/mo | Unlimited 480p generation |
| ChatGPT Pro | $200/mo | 10,000 credits/mo, up to 1080p at 20s |
API Access (Active Until September 24, 2026)
| Tier | Max Resolution | Duration Options | Price |
|---|---|---|---|
| Sora 2 | 720p | 4s / 8s / 12s | $0.10/sec |
| Sora 2 Pro | 1024p | 10s / 15s / 25s | $0.30–0.50/sec |
At the Sora 2 tier, a 12-second clip at 720p costs $1.20. At the Pro tier, a 25-second clip at 1024p runs $7.50–12.50 depending on complexity. That adds up fast for any production workflow.
What Sora 2 Did Well
Physics and Motion Realism
Sora 2 was a genuine step forward in how AI handles physical interactions. Missed basketball shots rebounded off rims naturally instead of teleporting into the hoop. A gymnast’s routine reflected actual weight, balance, and momentum. For short clips where realistic motion mattered, Sora 2 delivered results that competitors struggled to match at the time of release.
Native Audio Generation
Unlike earlier models that required separate audio in post-production, Sora 2 generated synchronized dialogue, background ambience, and sound effects alongside visuals. The audio was not perfect — voices could sound slightly flat in complex scenes — but the integration eliminated a full step from the production pipeline.
Controllability and Direction
Sora 2 introduced masking and in-painting for video, along with a “Cameo” feature that let users inject real people, animals, or objects into generated scenes. The model followed multi-shot instructions more reliably than its competitors, making it feel less like a slot machine and more like an actual creative tool.
Where Sora 2 Fell Short
Text and Fine Detail Rendering
Brand logos appeared garbled. On-screen text was consistently unreadable. Fine details drifted between frames. For any use case involving visible text — tutorials, infographics, branded content — Sora 2 output required heavy post-editing or was simply unusable.
Duration Limits
Clips maxed out at 10–25 seconds depending on your plan. That is fine for TikTok or Instagram Reels. It is not fine for a 30-second ad, a product demo, or anything resembling long-form content. Stitching multiple clips introduced continuity problems that Sora could not solve on its own.
Aggressive Content Filters
Users reported that Sora’s safety guardrails frequently blocked harmless prompts with false copyright or safety violation flags. Several reviewers described the experience as a “7.5 out of 10 tool trapped in a 5 out of 10 access system.” The friction was bad enough to push creators toward less restrictive alternatives.
Quality Degradation Over Time
Multiple users noticed that output quality declined in the months after launch, suggesting OpenAI may have throttled the model to manage compute costs. This eroded trust with early adopters who had built workflows around Sora’s initial capabilities.
Why OpenAI Shut Sora Down
Three factors drove the decision:
- Compute costs were unsustainable. Video generation is orders of magnitude more expensive than text or image generation. At roughly $1 million per day in infrastructure costs, the math never worked.
- User growth stalled. After peaking at one million users, the audience shrank. A planned $1 billion partnership with Disney collapsed.
- Strategic priorities shifted. OpenAI redirected resources toward coding tools and enterprise products where revenue is more predictable and margins are healthier.
Who Should Still Use the Sora API?
With the API remaining active until September 2026, there are a narrow set of valid use cases:
- Developers building video features who need to test integration before migrating to another provider
- Content creators producing short-form social clips where Sora 2’s motion quality still holds up
- Researchers benchmarking AI video generation quality across models
For anyone starting a new project, building on a platform with a published end-of-life date is a risk. You should evaluate alternatives first.
How Sora Compares to Alternatives
The AI video generation space has moved fast since Sora’s shutdown announcement. Here is where the main competitors stand:
| Tool | Strength | Free Tier | Max Duration |
|---|---|---|---|
| Kling 3.0 | Motion realism | Yes | 2 min |
| Google Veo 3.1 | Synchronized audio | Yes (via AI Studio) | 8s |
| Runway Gen-4.5 | Cinematic control | Trial credits | 40s |
| Seedance 2.0 | Overall quality benchmarks | Yes | 15s |
| Pika 2.2 | Ease of use | Yes | 10s |

The Verdict
Sora 2 was technically impressive. The physics simulation, native audio, and directorial control set a high bar when it launched. But the economics did not work, the access experience frustrated users, and OpenAI ultimately decided video generation was not where it wanted to compete.
If you are already using the Sora API and have workflows in place, you have until September 24, 2026 to migrate. If you are evaluating AI video tools for the first time, start with Kling AI or Runway — both are actively developed and not going anywhere.

Frequently Asked Questions
Is Sora still available in 2026?
The Sora app was discontinued on April 26, 2026. The API remains active until September 24, 2026. After that, Sora will be fully retired.
Why did OpenAI shut down Sora?
Unsustainable compute costs (roughly $1 million/day), declining user numbers, and a strategic decision to focus on coding and enterprise products.
What is the best alternative to Sora?
It depends on your priority. Kling 3.0 leads on motion realism, Runway Gen-4.5 on creative control, and Google Veo 3.1 on audio sync. See our best AI video generators guide for the full comparison.
