Negative prompt
Related tutorialA negative prompt tells the model what to avoid, rather than what to include. You list unwanted elements such as blurry, extra fingers, watermark or low resolution, and the model steers its output away from them during generation. It works alongside the main prompt and is one of the simplest ways to clean up common artifacts.
In tendre.AI you don't need one for images or videos: Krea 2 and LTX 2.5 work from the main prompt alone, so you describe what you want to see instead. The field remains for sound (sound effects and soundtracks), where it keeps music and voices out.
