This is 100% true. There are entire nodes/pipelines in programs like ComfyUI that are designed to take a simple prompt and "enhance it" which usually involves making it more verbose, adding detail, etc depending on the target model.
Original Prompt: "Man with Trapezoid Head"
AI Expansion:
Portrait of a man with a trapezoid-shaped head, sharp geometric facial structure, angular jawline wider at the top and narrowing toward the chin, realistic skin texture, detailed pores, dramatic studio lighting, ultra-detailed, 85mm lens, shallow depth of field, dark neutral background, cinematic, photorealistic, 8k resolution.
Note: Most people (outside the generative space) won’t pick up on this but in many cases if don't prompt otherwise, you’ll often end up with a prompt that’s better suited to older, keyword‑based models like Stable Diffusion which rely heavily on specific sets of positive and negative prompt keywords more akin to magical incantations to improve the output.
