Portrait — Side-by-Side Results
Prompt
"Portrait photo of a 20s woman with shoulder-length wavy dark hair in a loose beige knit sweater and high-waisted jeans, holding an iced latte and glancing toward the phone camera with a relaxed half-smile like an Instagram story. Shot in a cozy neighborhood café by a window with natural daylight, shallow depth of field and warm bokeh from background lights, 85mm lens feel with crisp focus on her face. Candid, mid-sip moment with one elbow on the table, minimal makeup, slightly messy hair, authentic UGC vibe."

Verdict
Pick Grok Imagine if your portrait work prioritizes creative direction, cinematic mood, and high-detail photorealism at a lower per-image cost. It’s a strong choice for generating lots of headshot variations, testing styling ideas, or building environmental portraits with more artistic range.
