Sora 2 is OpenAI’s video model, distinguished by physics realism — objects, collisions and motion that obey the rules of the physical world more convincingly than most rivals — and synchronized audio. For ChatGPT users it’s the most integrated way to go from prompt to clip.
In practice, access has been the wrinkle: through 2026 Sora’s availability and route to the API have shifted, and some trackers describe its public footprint as changing. Treat its status as a moving target and verify current access before building on it.
When it’s available, it’s a strong choice for physically plausible scenes and previsualization. If you need guaranteed, stable production access today, Veo 3.1 and Kling 3.0 are the safer bets.
