Why Did OpenAI Shut Down Sora?
On March 24, 2026, OpenAI CEO Sam Altman told staff that the company would wind down Sora — its standalone video app, developer API, and video generation inside ChatGPT — effective immediately. The announcement came just one day after OpenAI published a safety guide for Sora, making the shutdown feel especially abrupt.
The official farewell from Sora's account:
| "We're saying goodbye to the Sora app. To everyone who created with Sora, shared it, and built community around it: thank you. What you made with Sora mattered, and we know this news is disappointing. We'll share more soon, including timelines for the app and API." — Sora (@soraofficialapp), March 24, 2026 |

Based on reporting from The Wall Street Journal, The Verge, and Axios, the reasons boil down to:
-
Compute costs vs. revenue: Video generation is GPU-intensive. Sora's monthly downloads had fallen from a peak of 3.3 million to roughly 1.1 million — far too small relative to the infrastructure cost.
-
Strategic refocus: OpenAI is concentrating resources on GPT-5.x, Codex, and its upcoming superapp ahead of a potential IPO. Video was deemed a "side quest."
-
Copyright pressure: Studios including Disney, and groups like CODA (representing Studio Ghibli), had formally demanded OpenAI stop training on their IP.
-
Fierce competition: Google Veo 3.1, Kling 3.0, and Seedance 2.0 had caught up — and in most benchmarks, surpassed — Sora's output quality.
What This Means for Buble.ai Users
The Sora 2 and Sora 2 Pro models on Buble.ai will be removed once OpenAI's API goes offline. If you've been using them, here's what to do:
-
Download any previously generated Sora videos from your dashboard now.
-
New Sora generation requests will stop working once the API is shut down.
-
All other models on Buble.ai — Kling 3.0, Veo 3.1, Wan 2.6, and Seedance 2.0 — are fully operational and unaffected.
| ⚡ The good news: according to the Artificial Analysis Video Arena (March 2026), Kling 3.0, Veo 3.1, and Seedance 2.0 all score higher than Sora 2 on output quality. Switching isn't a downgrade — for most use cases, it's an upgrade. |
