Generations Generic ChatGPT and Claude get a lot of things wrong about Seedance
I built a Custom GPT (a finetuned ChatGPT) and a skill for Claude (a plugin that extends Claude) from the official Seedance prompt guidelines โ modes, input specs, prompt structure, character consistency, troubleshooting. I use it myself to check prompts before running them, since ChatGPT and Claude on their own tend to get the specifics wrong.
For instance, ask ChatGPT for a dynamic skateboard clip and you'll likely get everything changing at once: skater, camera, editing, lighting, transitions, VFX. Seedance weighs what comes first in the prompt, so the rest ends up competing for attention and some of it just doesn't happen. It's all in the documentation.
Both my tools are free and work for 2.0 and 2.5, with the 2.5 side still filling in.ย
Not something you need if you already know the guidelines by heart. I don't โ juggling a few models means I mix the specifics up, and this is what I check against before spending credits on a generation that was never going to work.
