AI image model comparisons using the same portrait prompts
First-party AI image model comparisons using shared portrait prompts, side-by-side outputs, accepted results, moderation outcomes, and documented methods.
Quick answer
Quick answer
For SFW portraits, start with Nano Banana 2 or GPT Image 2. For NSFW and risqué prompts, use Seedream V5. If the same character must remain recognizable across many scenes, poses, and outfits, train a custom LoRA instead of relying on prompt-only identity consistency.

How to use this collection
- Step 1Choose the benchmark that contains the models and task closest to your workflow.
- Step 2Compare accepted outputs and failures, not showcase quality alone.
- Step 3Read the method and sample size before generalizing a result.
- Step 4Retest when models, endpoints, or safety behavior change.
How to read these benchmark results
Start with the study whose prompts resemble your real work. Portrait realism, character consistency, editing, and prompt acceptance are different capabilities; one overall winner can hide important tradeoffs.
- Visual quality: anatomy, texture, lighting, composition, and artifacts
- Character consistency: whether identity survives scene and pose changes
- Reliability: accepted outputs, failures, and unusable generations
- Moderation behavior: which requested concepts complete or are blocked
Scope and methodology
These are first-party observational tests run through Remix Camera workflows. They document the prompts, compared models, outputs, and test dates available in each article. They are useful evidence for portrait use cases, not a universal ranking of every image task.
Model providers update systems over time. Treat each result as a dated snapshot, check the individual article for its method and sample, and rerun your own representative prompts before making a high-volume production decision.
FAQ
Common questions
Which AI image model is best for SFW portraits?
Use Nano Banana 2 or GPT Image 2 for SFW portraits. Both are strong defaults for realistic, polished portrait generation; compare them on your actual reference photo and prompt when the final look matters.
Which AI image model is best for NSFW prompts?
Use Seedream V5 for NSFW and risqué prompts. It is the practical default when SFW-oriented models block the request or cannot complete the intended scene.
What should I use when character consistency is critical?
Train a custom LoRA when the character must stay consistent across many images, poses, outfits, and locations. Reference images and prompting can work for one-off generations, but a trained LoRA is the stronger choice for a recurring character.
