Hi @true bone. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
Sora 2 is the newer generation of Sora, and most of what’s documented now is about Sora 2 (the app and API). There isn’t a full side‑by‑side spec sheet in the sources, but here’s what is clear:
1. Model generation and naming
-
Sora 1
- Referred to simply as “Sora” or “Sora 1” and “Sora 1 Turbo” in the web experience. [Generating videos; Sora app FAQ]
- Sora 1 on web is being phased out: “the Sora 1 web experience will eventually be deprecated.” [Generating videos]
-
Sora 2
- Described as “our new powerful media generation model” and “next‑generation model, Sora 2.” [Sora 2 model; Sora app intro]
- Powers the Sora app (iOS/Android) and sora.com in its new form. [Getting started]
2. Quality and capabilities
- Sora 2 improves realism, physics, and instruction‑following compared to earlier Sora. [Getting started]
- It generates video with synchronized audio by default; you can describe ambience, dialogue, etc., in the prompt. [Getting started; Video guide]
The sources don’t explicitly say how Sora 1 handled audio or physics in a quantitative way, only that Sora 2 is the “next‑generation” model with these improvements.
3. Where you use them
-
Sora 1
- “Sora 1 on Web” at
sora.chatgpt.com/explore; that specific experience is called out separately and will be deprecated. [Creating images on Sora; Generating videos] - Your old Sora 1 creations remain in your sora.com library even as Sora 2 rolls out. [Sora app FAQ]
- “Sora 1 on Web” at
-
Sora 2
- Available via the Sora app (iOS now, Android later) and sora.com with “deeper controls.” [Getting started]
- Also exposed as API models
sora-2andsora-2-profor developers, with configurable resolution and duration. [Sora 2 model; Sora 2 Pro model; Prompting guide]
4. Usage & plans
- Sora 1 web docs talk about Plus/Team/Pro requirements for video generation and “Sora 1 on Web” specifically. [Creating images on Sora; Sora billing FAQ]
- Sora 2 is tied to:
- The Sora app (invite‑based rollout, starting in US/Canada). [Getting started]
- Credits pricing for Sora 2 and Sora 2 Pro when you exceed included usage. [Credits & Sora 2]
5. Sora 2 vs Sora 2 Pro (within Sora 2 generation)
Once you’re on Sora 2, there are two API models:
sora-2: tuned for speed and exploration, cheaper per second. [Video guide; Sora 2 model]sora-2-pro: higher fidelity, more polished, slower and more expensive, with higher‑resolution options. [Video guide; Sora 2 Pro model]
