LinkedIn Professional Photo — Side-by-Side Results
Prompt
"A candid front-facing phone-camera portrait of a 28–35-year-old influencer with shoulder-length dark brown hair (neatly styled), wearing a navy blazer over a simple white tee and tailored trousers, holding their phone slightly above eye level and looking near the lens with an approachable, confident smile. Shot in a real coworking space lounge with a laptop and coffee cup on a table behind them, soft window daylight and realistic indoor ambient lighting, natural skin texture, minimal retouching like an authentic LinkedIn-ready Instagram story selfie. Keep it professional and well-groomed, neutral background tones, no dramatic shadows, true-to-life colors."

Grok Imagine Strengths
- Strong photorealistic rendering for crisp, LinkedIn-style headshots with natural lighting and convincing skin texture
- Efficient for generating multiple candidate portraits quickly thanks to lower per-image cost (4 credits/image)
- High detail in hair, fabric, and facial features—useful for polished corporate looks (blazers, button-downs, subtle accessories)
- Works well for prompt-led variations (pose, background, framing) when you want a range of options fast
Seedream 4.5 Strengths
- Excellent image-to-image editing workflow for refining an existing headshot (background cleanup, wardrobe tweaks, lighting adjustments)
- High-resolution output that holds up well for profile crops and banner-adjacent use cases without looking soft
- Versatile style control—helpful for matching industry norms (finance formal, tech smart-casual, creator professional) while staying business-appropriate
- Stronger precision for iterative improvements when you need a specific, consistent look rather than many creative options
Verdict
If you want to generate a set of LinkedIn-ready portraits quickly and cost-effectively, Grok Imagine is the practical pick. It’s well-suited to producing multiple photorealistic headshot options (different crops, subtle pose changes, background variants) without burning through credits.
If your priority is controlled refinement—starting from a good image and polishing it into a final, corporate-safe headshot—Seedream 4.5 is typically the better fit, especially for background, lighting, and detail edits. The tradeoff is the higher cost at 16 credits/image, which makes it best for fewer, more deliberate iterations.
