AI video generation

Questions
How much does a video cost?
Each model is priced per second of finished video, and the Studio shows the total before you press Generate, from $0.041 for 4 seconds on Seedance v1.0 Pro Fast. A failed video costs nothing.
How long does a video take?
The Studio shows progress while the provider renders. You can leave the page; the video keeps rendering and appears in History when you return.
How long is my video kept?
The MP4 can be downloaded for 24 hours after it finishes, so save the ones you want to keep.
How many videos can I run at once?
Up to 2 videos per account can be in progress at the same time, and a video counts toward the 2 until its cost settles. Start the next one as soon as a slot frees.

9 of 23 models can add audio: Veo 3.1, Kling v3.0 Text-to-Video, Veo 3.1 Fast Generate, Kling v2.6 Text-to-Video, Veo 3.1 Lite Generate, Seedance v1.5 Pro, Kling v3.0 Image-to-Video, Seedance 2.5 and Kling v2.6 Image-to-Video. Audio is a toggle in the Studio and changes the per-second rate.

Can I generate videos from code?
Yes. The same models answer POST /v1/videos with an API key, and the OpenAI SDK's videos methods work unchanged. Video API docs
