Selection guide
Use these decision points when choosing a model.
Test it for multi-image edits — Seedream 4.5 is worth sampling when a brief combines several product, character, or style references. The 14-image capacity is the interface limit, not a recommended target.
Compare other versions when the controls or cost differ — If explicit 1K, 2K, and 4K selection matters, compare Seedream 4.0. If you want to assess basic 2K / high 3K settings at a lower fixed Kyeo price, add Seedream 5.0 Lite.
Run a controlled 2K-versus-4K test — Keep the prompt and references fixed, then run `basic` and `high`. Compare detail, text, subject preservation, and usable dimensions. Both settings cost 7 credits, and the 4K label alone does not establish content quality.

Nano Banana Pro
Nano Banana Pro supports text-to-image generation and reference-image editing on Kyeo AI, with 1K, 2K, or 4K output. Each 1K or 2K request costs 8 credits, while 4K costs 14. Resolution is an output-size tier, not a guarantee of quality, accuracy, or detail.

GPT Image 1.5 on Kyeo supports text-to-image and image-to-image with three aspect ratios and medium/high quality. Image editing accepts up to 16 JPG, PNG, or WebP references at 10 MB each. Medium costs 4 credits and high costs 22 credits. GPT Image 1.5 is OpenAI's deprecated previous image model.
