Sora was OpenAI's AI video generation platform producing photorealistic video with synchronized audio; discontinued March 2026.
Video Generation
8.5Sora 2 produced the most photorealistic AI video with synchronized native audio of any consumer platform at launch in September 2025; discontinued March 2026 before achieving commercial sustainability, making this score historical rather than actionable.
Content Creation
7.5iOS social app with creation, remixing, and sharing features drove strong early adoption; user count collapsed from peak of approximately 1 million to under 500,000 before shutdown announcement, reflecting difficulty converting demo quality into sustained daily creative workflows.
Marketing
7.0Disney partnership established a licensed character generation framework unique in the AI video market; partnership terminated with the product shutdown before commercial marketing workflows could be established at scale.
Research
8.0Sora's architecture demonstrated genuine advances in physics simulation and world modeling; OpenAI stated the research direction continues as a "world models" project separate from the consumer product.
Sora was OpenAI's text-to-video and image-to-video generation model, first revealed February 2024 and commercially launched December 2024. Sora 2, released September 30, 2025, added synchronized dialogue and sound effects, native audio generation, up to 25-second clip duration, and significantly improved physics simulation. OpenAI announced Sora's discontinuation on March 24, 2026, citing unsustainable compute costs estimated at $500,000–$1 million per day against fewer than 500,000 active users. The web and app experience ends April 26, 2026; the API ends September 24, 2026. OpenAI is urging all users to export content before shutdown. No replacement video product has been announced. New workflows should not be built on Sora.
Pricing
| Plan | Model | Usage Limits | Price |
|---|---|---|---|
| ChatGPT Plus | Sora 2 standard; up to 20-second clips; 720p–1080p | Limited monthly video generation credits shared with other ChatGPT features; exact generation count not publicly documented | $20/month |
| ChatGPT Pro | Sora 2 Pro; up to 25-second clips; higher resolution; priority queue | Higher generation allocation; access to Sora 2 Pro model at higher resolution | $200/month |
| API | Sora 2 standard and Pro endpoints; per-second billing | Per-second billing at $0.10–$0.50/second depending on model tier and resolution; Tier 2 account required (minimum $10 spend history) | pay-per-second |
| All tiers | Discontinued — no new subscriptions should be initiated; API deprecated September 24, 2026 | — | — |
Native audio generation and up to 25-second photorealistic clips set a quality bar competitors are still matching; shutdown six months after app launch left content creators without migration path and with content deletion risk if exports are not completed before April 26, 2026.
API launched September 30, 2025 at $0.10–$0.50/second; deprecated March 24, 2026 with final shutdown September 24, 2026 — insufficient runway for any production integration to reach commercial viability.
Sora 2's physics simulation and world modeling capabilities were genuinely novel research contributions; OpenAI confirmed the underlying research continues under a separate world models initiative after product shutdown.
Disney licensing partnership created a unique commercial use case for licensed IP in AI video, but was terminated with the product before any marketing workflows could be validated at production scale.
ChatGPT
Sora was accessed through ChatGPT Plus and Pro subscriptions; remaining video credits can be redirected to OpenAI's Codex coding tool per official guidance.
Runway
Primary professional alternative for users migrating from Sora; character consistency and Aleph editing cover the narrative video workflow Sora was positioned for.
Kling AI
Recommended for high-volume or budget-sensitive migrations from Sora; best duration-to-price ratio with physics simulation comparable to Sora 2.
Consider These Instead
Choose Runway Gen-4.5 for the most complete professional AI video production suite with Aleph post-generation editing and character consistency, starting at $12/month. Choose Google Veo 3.1 for native audio generation most comparable to Sora 2's synchronized audio capability, with up to 60-second clip length and enterprise API access via Google Cloud. Choose Kling AI 3.0 for the best cost-per-second ratio with up to 2-minute continuous clips and strong physics simulation starting at $6.99/month.
