When you write long prompts for Seedance, you're now told the moment you submit if you've gone over the limit.
What's different
- You're told at submit time. If the prompt is over Seedance's limit, hitting Generate shows a message right away — nothing is charged, and you don't wait in the queue for a failed generation.
- Roughly how long is the limit. About 20,000 Chinese characters (about 60,000 English characters) per request. Reference images, audio and video take up a small part of that, so the more media you attach, the slightly less room there is for text.
- When submitting from the CLI, MCP or the agent, the error tells you roughly how many characters to remove.
This applies to all Seedance models.
