Sunburst Portrait Style Comparison: Realism vs. Artistic Prompt Reference

A text-to-image portrait style demonstration using gpt-image-2.5-sunburst (the precision-first variant). The work uses no reference images; a single structured prompt compresses two directions—"realistic photographic portrait" and "artistic portrait"—into one composition: the subject is a half-body portrait in the same pose, with the left side leaning toward natural-light realism and the right side toward painterly color and brushwork, both sharing the same light direction to ensure consistency. 16:9 is chosen because the wide format suits side-by-side comparison, showing developers the difference in weight between "texture description" and "style description" in a prompt. Suitable as a prompt-writing reference, a model-selection comparison, and prototype validation for portrait-based commercial visuals (brand character imagery, editorial illustrations). Sunburst targets high-precision creative work and takes longer per request, so it is better suited to this kind of static output requiring detail fidelity than to low-latency batch scenarios.
