Apparently, OpenAI was in such a rush to release the Sora 2 API that they didn’t even make a playground for it, unlike their other models.
To my surprise, both Fal. ai and Replicate require you to buy their credits even though it’s BYOK api (bring your own key).
So, I decided to take the initiative and build a free, open-source, client-side webapp for the Sora 2 API. You can try it at https://sora2playground.com and find the repo at https://github.com/amirzak/sora2-playground
If you like it, I’d really appreciate a star on GitHub!
