Nano Banana Pro API - Kie.ai vs Unreal Person

Nano Banana Pro API on Kie.ai gives developers API access to Google DeepMind's Nano Banana Pro image model (Gemini 3.0 Pro Image) for text-to-image and image-to-image workflows. Kie.ai hosts the model behind a developer dashboard with a playground, API keys, usage logs, and documentation so teams can test prompts and ship integrations without running their own GPU stack.

The model targets sharper 2K output with intelligent 4K scaling, stronger text rendering inside images, and more stable character consistency than the earlier Nano Banana generation. Kie.ai positions the endpoint for production pipelines that need predictable visual quality across marketing assets, storyboards, product shots, and localized creative variants.

Developers call the API with a text prompt and optional reference images (up to eight JPEG, PNG, or WEBP files at 30MB each), then choose aspect ratio, resolution (1K, 2K, or 4K), and output format (PNG or JPG). A built-in playground mirrors runtime behavior before you wire REST or SDK calls into your app.

Kie.ai runs on a pay-as-you-go credit balance with per-image rates published on the product page, plus request logs, quota monitoring, and 24/7 support for production deployments.

Unreal Person generates photorealistic images of people who do not exist. Also known as #thispersondoesnotexist, the tool uses a generative adversarial network trained on billions of human faces to produce a unique, never-before-seen face with every click.

Unlike general text-to-image tools, Unreal Person is built around one-click random generation with no prompt box. You hit Generate and get a new face, cat, horse, art piece, or beach scene instantly. That makes it closer to the original ThisPersonDoesNotExist experience than Midjourney-style prompt workflows, though the site still lists upcoming DALL-E 2.0 and Stable Diffusion support.

Beyond human faces, Unreal Person offers separate generators for cats, horses, abstract art, beach scenes, and 3D chemical molecule visualizations. Each generator works the same way: click Generate to get a brand new image, then download it. You can also specify gender and age range when creating people.

The service is free with no account required. Unreal Person states it plans to stay free forever.
