GPT-Image 1.5 and Grok Imagine are two image-generation options in Influencer Studio designed for creators who need high-quality visuals fast. Both support text-to-image workflows and can produce detailed, polished outputs suitable for social posts, ads, thumbnails, and concept art.
The main differences come down to workflow flexibility and cost structure: GPT-Image 1.5 emphasizes prompt adherence and scene fidelity with tiered quality pricing, while Grok Imagine focuses on creative composition, photorealistic detail, and adds image-to-image editing at a flat per-image rate.
Side-by-Side Results
Prompt
"A 20s influencer with shoulder-length wavy brown hair, minimal makeup, wearing an oversized gray hoodie and black bike shorts, holds a phone up for a mirror selfie while glancing slightly toward the camera with a half-smile. She’s standing in a messy-but-cozy bedroom next to an unmade bed and a laundry basket, one hand tugging the hoodie hem like an outfit-check moment. Soft window daylight from the side, casual handheld phone-camera feel with a little grain like an Instagram Story."
