Also known as: prompt_strength
Prompt strength adjusts how much influence your text prompt has on the final image. Higher values push the model to follow the prompt more literally, while lower values let the model prioritize image coherence and natural aesthetics.
What It Does
This parameter acts as a dial between prompt faithfulness and image quality. Unlike guidance scale (which modifies the classifier-free guidance weighting), prompt strength is a separate model-level control that scales the text conditioning signal. At lower values, the model focuses on producing a visually coherent and aesthetically pleasing image, even if it departs from some prompt details.
At higher values, the model aggressively incorporates prompt elements, which can sometimes come at the cost of natural composition or visual harmony.
Value Ranges
Low (0.1–0.3)
Prompt is treated as a soft suggestion. The model prioritizes visual quality and may omit or reinterpret prompt details.
Mid (0.4–0.7)
Balanced prompt influence. Most prompt elements appear while maintaining natural-looking results.
High (0.8–1.0)
Strong prompt adherence. The model tries to include every detail specified. May produce less natural compositions in complex prompts.

Tips
- Default is often 0.8–1.0 for most models. Only reduce it if the image looks unnatural.
- If small prompt details keep getting ignored, try increasing prompt strength before adding more words.
- This is model-specific — not all models expose this parameter.
- Works well in combination with guidance scale: increase guidance for concept adherence, prompt strength for detail inclusion.
