Sora API即將關閉:AI影片生成龍頭已換人 | Sora API Shuts Down: AI Video Generation Has a New King

🇹🇼 Sora API即將關閉:AI影片生成龍頭已換人

Sora API 關閉倒數只剩不到兩個月:OpenAI 證實 Sora-2 API 將於 2026 年 9 月 24 日正式停止服務,曾經代表AI影片生成最高規格的 Sora,就此走入歷史。與此同時,龍頭寶座早已悄悄換人——中國 ByteDance 推出的 Seedance 2.0,目前同時稱霸 Artificial Analysis 影片競技場的文字轉影片與圖片轉影片雙榜單,把 Sora 2、Google Veo 3、Kling 3.0 全部甩在身後。

Sora API 為什麼關閉?

答案很直接:不划算。OpenAI 揭露的數字顯示,Sora 每天燒掉約 100 萬美元運算成本,總營收卻只有約 210 萬美元,活躍用戶數還持續下滑。OpenAI 因此分兩階段收攤:網頁與 App 版本已在 2026 年 4 月 26 日關閉,Sora-2 與 Sora-2 Pro 的 API 端點則會在 9 月 24 日徹底停止運作,屆時帳號資料也會被永久刪除,開發者必須提早匯出內容。

AI影片生成龍頭換人了:Seedance 2.0 是什麼?

ByteDance Seed 團隊打造的 Seedance 2.0,在 Artificial Analysis 榜單上以 Elo 1,269(文字轉影片)與 1,351(圖片轉影片)雙料登頂。它採用「音影同步生成」架構,不是先做畫面再配音,而是把聲音跟畫面放進同一個生成過程一起處理,讓對嘴、環境音跟畫面同步的效果明顯更自然,單次最長可產出 15 秒同步影音內容。

還在用 Sora API 的開發者該怎麼辦?

如果你的產品串接了 Sora-2 或 Sora-2 Pro,現在就該規劃遷移。常見替代方案:

  • Google Veo 3.1:目前唯一支援 48kHz 同步對白的電影級模型,適合敘事型內容
  • ByteDance Seedance 2.0:雙榜登頂,適合需要高品質、多語言對嘴的場景
  • Runway Gen-4.5:綜合排名雖掉出前十,但編輯控制度仍是團隊剪輯工作流的安全牌
  • Kling 3.0:性價比選項,適合大量生成、快速迭代的用例

小克實測心得

這次 Sora 收攤給所有仰賴單一 AI 服務的團隊上了一課:就算是 OpenAI 的旗艦產品,商業模式撐不住照樣說關就關。如果你的產品邏輯綁死在特定模型 API,建議至少留一條備援路線,別把雞蛋放在同一個籃子裡。AI影片生成這個賽道換人做莊的速度,比想像中還快,這次中國團隊是玩真的。

好不好用,試了才知道。


🇺🇸 Sora API Shuts Down: AI Video Generation Has a New King

Sora API shutdown is now less than two months away: OpenAI has confirmed the Sora-2 API will be fully discontinued on September 24, 2026, closing the book on what was once the gold standard of AI video generation. Meanwhile, the crown has already changed hands — ByteDance's Seedance 2.0 currently tops the Artificial Analysis Video Arena leaderboard in both text-to-video and image-to-video, beating Sora 2, Google Veo 3, and Kling 3.0 across the board.

Why Is the Sora API Shutting Down?

The reason is simple: the numbers didn't work. OpenAI's disclosed figures show Sora burned roughly $1 million a day in compute while generating only about $2.1 million in total revenue, with active users falling steadily. OpenAI opted for a two-stage wind-down: the web and app versions closed on April 26, 2026, and the Sora-2 and Sora-2 Pro API endpoints go dark on September 24, after which all account data is permanently deleted — so developers need to export content now.

Who's the New Leader in AI Video Generation?

ByteDance's Seed team built Seedance 2.0, which now holds Elo 1,269 for text-to-video and 1,351 for image-to-video on Artificial Analysis — first place in both categories. Its architecture generates audio and video together in a single unified pass instead of layering sound on afterward, producing noticeably better lip-sync and ambient audio realism, with up to 15 seconds of synchronized output per generation.

What Should Developers Still on the Sora API Do?

If your product integrates Sora-2 or Sora-2 Pro, start planning your migration now. Common alternatives include:

  • Google Veo 3.1 — the only model with 48kHz synchronized dialogue, best for narrative content
  • ByteDance Seedance 2.0 — tops both leaderboards, strong for high-quality multilingual lip-sync
  • Runway Gen-4.5 — dropped out of the top 10 overall, but still a safe pick for teams needing fine editing control
  • Kling 3.0 — a cost-effective option for high-volume, fast-iteration use cases

Kit's Take

The Sora shutdown is a lesson for anyone building on a single AI vendor: even OpenAI's flagship product gets killed when the unit economics don't work. If your product logic is locked into one model's API, keep a fallback path ready — don't put all your eggs in one basket. The AI video generation race is changing leaders faster than most people expected, and this time a Chinese team is genuinely winning.

Good or not, you won't know until you try it.
