Hyperrealistic renders indistinguishable from photographs — see how these models compare with real AI-generated outputs.
Full comparisonCompare Models (select 4)
Flux 2 and Flux Ultra 1.1 are both built to create photorealistic images inside Influencer Studio, but they approach “camera-real” results differently. Flux Ultra 1.1 prioritizes premium realism and micro-detail in a single generation, while Flux 2 balances strong realism with broader creative control—especially when you need edits, iterations, or customization.
If your goal is hyperrealistic renders that read as authentic photography (skin texture, natural lighting, believable materials, and clean backgrounds), the best choice depends on whether you value maximum out-of-the-box fidelity (Ultra 1.1) or a more flexible production workflow (Flux 2) that includes editing tools and LoRA support.
Photorealistic — Side-by-Side Results
Prompt
"Hyperrealistic DSLR-quality photo of a mid-20s woman with shoulder-length wavy dark brown hair and light freckles, wearing an oversized gray hoodie and black bike shorts, holding her phone slightly above eye level for a casual selfie while looking near the camera with a half-smile. She’s in a small sunlit kitchen making iced coffee, one hand stirring a glass cup on a cluttered counter (oat milk carton, keys, a messy fruit bowl), soft natural window light and realistic shadows with visible skin texture and natural imperfections. Candid Instagram-story vibe, unposed and relatable, true-to-life color and accurate light physics."

Flux 2 Strengths
- Photorealistic output with flexible workflows: strong realism plus robust image-to-image editing for refining “photo-like” results
- LoRA fine-tuning support for consistent photorealistic subjects, wardrobes, or brand aesthetics across many images
- Up to 4MP output for sharper “camera-grade” detail, especially helpful for crops, product shots, and close-ups
- Versatile editing capabilities (image-to-image, style transfer) to correct lighting, composition, and realism issues without restarting
- Face-swap support for maintaining identity consistency in photorealistic influencer-style content
Flux Ultra 1.1 Strengths
- Exceptional out-of-the-box photorealism with premium detail—often closer to “straight from a camera” on first pass
- Ultra-high detail rendering for textures like skin pores, fabric weave, hair strands, and realistic specular highlights
- Strong natural lighting and material realism for scenes that need to look physically believable
- Simple, premium-focused workflow when you mainly need best-possible generation quality rather than extensive editing
Verdict
Choose Flux Ultra 1.1 when photorealism is the only priority and you want the highest perceived detail and realism with minimal iteration—especially for hero images, close-up portraits, and high-end product-style shots.
Choose Flux 2 when you still want strong photorealism but also need control: iterative image edits, consistent identity via face-swap, and LoRA-based customization for repeatable, on-brand “real photo” campaigns. Cost-wise, Ultra 1.1 is also efficient at 16 credits/image, while Flux 2 ranges from 16–22 credits/image depending on the option you use.
