Fibo 1.5 Portrait Style Reference: Dual-Track Demo of Realism and Artistic Rendering

Using the few-step distilled sampling pipeline of fibo-gen-1.5/text-to-image, generate a vertical portrait, and present side by side, with the same subject and same composition, the differences in prompt phrasing between the "realism" and "artistic" styles. This model family adopts a JSON-native structured prompting paradigm, describing attributes such as subject, lighting, color, and lens in separate fields; combined with 4–6 steps and CFG=1.0 guidance-free sampling, it achieves strong prompt adherence and attribute controllability under relatively short prompts. This entry deliberately uses only short natural-language prompts, serving as a lower-bound reference under the constraint that "ordinary short prompts yield limited benefit." The work is suitable for setting the early style direction of portrait commercial images, social media avatars, and character design sketches, and is also suitable for developers as a comparison baseline to observe output differences between structured long prompts and short prompts under the same seed and the same aspect ratio.
