Questions before you create?
Clear answers about the model, hosted generation, credits, and billing.
Yes. The OpenSora 2 model is free and open source when you download and run it on your own hardware. Our hosted generation service is optional: it provides managed GPU infrastructure and uses credits for each video you create.
The starter trial includes 600 credits, valid for 30 days. It is a one-time purchase available once per account, so you can try hosted generation without starting a subscription.
It depends on the product. Subscription credits roll over for the monthly plans currently shown in our catalog. The pay-once starter trial is valid for 30 days, while pay-once credit packs are valid for 365 days. Check the product details at checkout for the terms that apply to your purchase.
The OpenSora model is released under the Apache 2.0 license, which permits commercial use subject to that license. Our hosted plans currently list commercial use as included. You remain responsible for the prompts, source materials, output, and any third-party rights, so this is not a blanket legal guarantee for every use case.
Payments are processed through Stripe Checkout. If you choose a subscription, you can cancel it from your account; cancellation stops future renewals rather than removing access you have already paid for.
