Nano Banana Pro API - Kie.ai vs Fooocus

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.

Fooocus.one is a browser-based image generation platform built around the Fooocus workflow. You can create images from text prompts, edit photos with inpainting, swap faces, restore old pictures, and upscale results without installing software locally.

The platform runs Fooocus on hosted GPU servers, with unlimited online generation included on paid plans. It supports SDXL models, multi-prompt inputs, image prompts for style reference, and controls for aspect ratio, contrast, and sharpness. Separate pages cover background removal, photo restoration, and face swapping with InsightFace.

Beyond core generation, the site bundles model pages for FLUX, GPT Image, Gemini Omni, WAN, and Nano Banana. The playground offers Flux Schnell generation from a simple prompt interface, while paid tiers unlock inpainting, metadata access, faster speeds, and commercial licenses.

Fooocus.one suits digital artists, content creators, and hobbyists who want Fooocus-style image creation in the browser. The site also links to the open-source Fooocus GitHub repository and a Google Colab notebook for users who prefer running the project locally.
