Sora 2 is OpenAI's cinematic video model — top-tier quality, but India-restricted and with its API being retired in late 2026.

NOT officially available in India and the API is sunsetting (Sept 2026) — risky to build on; prefer Veo / Kling.
No native INR/free path; Indians access only via ChatGPT Plus or third-party resellers.
For Indian creators, Veo 3.1 and Kling 3.0 are more accessible and longer-lived choices.

Via ChatGPT Plus/Pro; API ~$0.10/sec (720p) to ~$0.70/sec (Pro 1080p). Not officially in India; API sunsetting.
