Frequently Asked Questions about Kie Ai

What's the difference between Nano Banana API and Nano Banana Pro, and when should I use each?

Nano Banana API runs Gemini 2.5 Flash and costs around $0.02 per image, making it best for high-volume batch work and fast turnarounds. Nano Banana Pro uses Gemini 3 Pro for photorealistic results with precise text rendering, which costs more but handles professional creative asset generation and detailed visual work. Pick the standard tier for speed and cost; pick Pro when image quality and text accuracy matter.

Can I edit multiple images in a single request, and what formats can I export?

Kie.ai accepts up to 10 input images per editing request, which is useful for batch transformations and style transfers. You can export as PNG or JPEG in multiple aspect ratios including 1:1, 9:16, 16:9, and several others, plus auto scaling. The API supports up to 4K resolution depending on your tier and request.

How does the 64K context window help, and what can I do with it?

The 64K context window lets you write complex, multi-step prompts that describe intricate creative briefs without hitting length limits. This matters when you need Kie.ai to understand detailed style requirements, layered edits, or semantic reasoning across several images at once. It's built for workflows where a single prompt needs to coordinate a lot of visual information.

What's the actual per-image cost if I buy credits in bulk?

The standard tier costs 4 credits per image, or about $0.02 each. Kie.ai offers top-up bonuses of 10 percent on larger purchases, which brings the effective cost down to around $0.018 per image. Check their pricing page for current top-up tiers and credit packages.
