Social Media Ad — Side-by-Side Results
Prompt
"A late-20s woman with shoulder-length wavy brown hair in a cozy oversized oatmeal sweater and black leggings sits by a bright café window, looking just past the phone camera with a natural half-smile while holding an iced matcha and a sleek reusable glass tumbler with a visible logo label. Candid “quick story update” vibe—one hand on the cup, the other resting near a laptop and croissant on a small table, soft natural daylight, slight handheld phone-camera angle like an Instagram Story ad. Clean, aspirational but relatable product placement, minimal background clutter, warm tones, sharp focus on her face and the tumbler."

Flux Ultra 1.1 Strengths
- Premium, ultra-high-detail photorealism for polished hero images and flagship campaigns
- Strong perceived production value (lighting, textures, materials) that reads as “studio-grade” in-feed
- Great for close-ups and product-forward compositions where micro-detail matters
- Best choice when you want fewer iterations and a more “final render” look
Grok Imagine Strengths
- Cost-efficient at 4 credits per image—ideal for high-volume ad variant generation and testing
- Supports image-to-image, making it easier to iterate from an existing concept, reference, or prior winning creative
- Strong creative composition options for lifestyle, UGC-inspired, and narrative ad scenes
- Fast experimentation for hooks, backgrounds, props, and multiple angles without premium spend
Verdict
Flux Ultra 1.1 is the better pick when your social ads must look premium and photorealistic with maximum detail—think product launches, high-end brands, and hero creatives that need to feel “shot in studio.” The tradeoff is cost: at 16 credits per image, it’s best reserved for fewer, higher-impact outputs.
Grok Imagine is the practical choice for performance marketers who need lots of variations, rapid iteration, and the flexibility of image-to-image workflows. At 4 credits per image, it’s well-suited to always-on campaigns, testing new angles weekly, and producing multiple creative directions before selecting a final winner.
