[OpenAI Sora API] Clarify and improve extension pricing

Sooooo I wanted to test the updated Video and Sora 2 API updates and features that OpenAI released yesterday, which includes a new “edit” function replacing the remix function so that it now matches the same function on the app, a new character saving feature for objects, items, or non human character (basically like Cameos on the app now but no human characters yet), and then my most awaited feature which is the ability now to extend API Sora 2 gens. BUT! Here’s the kicker. And I learned this the hard way so you don’t have to bahaha. The new extension pricing is absolutely cooked atm. And it hasn’t even been adequately communicated properly in the updated documentation, so it feels a bit shady imo. In essence, let’s say you generate an 8 second Sora 2 clip and you pay $0.8 - which is the normal 10 cents per second price. Then, you want to extend that clip another 12 seconds. So most would assume that you’d be at 20 seconds all up, so $2 in total right? Nope. You get charged $0.8 for the first 8 secs, then you get charged an ADDITIONAL $2 for the 12 second extension. Because they currently are re-billing you for the previously generated 8 seconds. So I made the error in my new Sora 2 web app of pressing gen on an extend, it got stuck, I pressed it again, and suddenly I had 2 of the same gens running both bringing the same video to 32 seconds, so I got charged an additional $6.40 💀. My recommendation is if you want to test it and save money in the process, generate a long first clip ie like 16 or 20 seconds. That way, it will cost either $1.60 or $2 straight up - and then if you do want to extend, go for another 16 or 20 second extension. You will still pay extra, but if you mess with like 4/8/12 second gens with multiple extensions, you just end up paying like double/triple the usual price and it’s a big waste of money. Anyway, I thought I’d share for discussions sake and to inform people before they get too excited lol. It is still amazing to have, but I wish the pricing would be more clear and transparently presented on the API documentation. And I hope OpenAI will alter how they charge for extensions because imo it seems unreasonable to charge you twice for something you’ve already generated, just to be able to extend/stitch it together. Especially when extensions are still unreliable. I’d still say only 60-70% of them are coming out mostly seamless, with others having glitches as it extends. What do you guys think about the new updates? Anything you’d like to see in the future?
