How SD process the strength parameter text such as "(amphibic:1.2)"?

[chg0901]

I want to discuss an issue. In the text prompts of Stable Diffusion, there are often many strength parameters. For such prompt texts like ‘fractal art:1.2’, ‘fantasy style (amphibic:1.2)’, do they have a dedicated text encoder? How is it processed?

If there are similar prompt requirements (adding strength parameters), how should the model be trained or adjusted, or how should the training data be prepared?
