Seedream 5 Pro for a hero frame where texture and light are the point. - **[Nano Banana 2.1](https://meetkuro.com/models/nano-banana-2.1.md)** — Google's latest fast image model: fourteen references, sharp text, and output up to 4K. from 3 credits · Google - **[Seedream 5 Pro](https://meetkuro.com/models/seedream-5-pro.md)** — Seedream with more capability per pass, priced by size rather than given away. from 4 credits · ByteDance ## Side by side | — | Nano Banana 2.1 | Seedream 5 Pro | | --- | --- | --- | | Cheapest | 3 credits | 4 credits | | Aspect ratios | 1:1 1:4 1:8 2:3 3:2 3:4 4:1 4:3 4:5 5:4 8:1 9:16 16:9 21:9 | 1:1 4:3 3:4 16:9 9:16 3:2 2:3 21:9 | | Reference images | 14 | 7 | Read from Kuro's model catalog when this page was built. This page shows no outputs from either model; the prices and limits are the comparison. ## What each costs **Nano Banana 2.1** - Resolution · 1K: 3 credits (≈ $0.07) - Resolution · 2K: 4.5 credits (≈ $0.11) - Resolution · 4K: 9.5 credits (≈ $0.23) **Seedream 5 Pro** - Size · 1K: 4 credits (≈ $0.10) - Size · 2K: 7.5 credits (≈ $0.18) Dollar figures are approximate, at the Starter plan's rate of $19.00 for 800 credits. ## Which one Both take references, both handle the ordinary run of product shots, people and scenes, and at 1K they cost nearly the same. The choice is about what the picture has to get right. Seedream 5 Pro is the finishing model of its family. Against Seedream 5 Lite it renders finer skin, fabric and complex light, follows an explicit lighting direction more closely, and holds a face more steadily across up to ten references. It works best on a prompt written as an inventory of what is in the frame, in depth order, kept under about eighty words, with references carrying the detail the words cannot. Nano Banana 2.1 reads a prompt the way an editor does and is the family that best preserves a reference's identity. That is why Seedream's own guide sends a face, a product or an earlier frame that must be matched closely to Nano Banana. It seats fourteen references against Seedream 5 Pro's ten. It also frames fourteen aspect ratios against eight. Both have 21:9; what Seedream lacks is 4:5, 5:4 and the strips from 1:8 to 8:1. At 1K Nano Banana 2.1 is 3 credits and Seedream 5 Pro is 4. At 2K it is 4.5 credits against 7.5. Only Nano Banana goes to 4K, at 9.5 credits. So Seedream 5 Pro costs more at every size it offers, and what the extra buys is finish rather than capacity. Two things to know about Seedream 5 Pro before building on it. It screens every request for sexual content once prompt and references are combined, and a blocked brief needs rewriting rather than resending. And it has failed at the provider on some pairs of references that Seedream 5 Lite took without trouble, so a multi-reference run that fails is worth trying on Lite. On both models, rewording a prompt to fix one detail re-rolls the whole picture; edit the finished image with only the change instead. So identity, unusual shapes, 4K or volume go to Nano Banana 2.1. A single frame that will be looked at closely, carried by skin, cloth and light, goes to Seedream 5 Pro, ideally after the composition has been found somewhere cheaper. Seedream 5 Lite, at 3 credits for 2K or 3K, is that cheaper place within the same family. ## Related comparisons - [Nano Banana 2.1 vs GPT Image 2.5](https://meetkuro.com/compare/nano-banana-2.1-vs-gpt-image-2.5-flare.md): GPT Image 2.5 when the picture is mostly instructions or lettering.

Then it has to be Nano Banana 2. ## When neither is the right pick Each model's prompting guide names the jobs it hands to another model. Both lists, as the guides write them: ### Use something other than Nano Banana when… - You want painterly or stylised texture: [FLUX.2 Pro](https://meetkuro.com/models/flux-2-pro.md). - The frame holds dense small type, or a long instruction placing several objects: [GPT Image 2.5 Flare](https://meetkuro.com/models/gpt-image-2.5-flare.md). - It is an everyday product or lifestyle shot at a standard ratio: [Seedream 5 Lite](https://meetkuro.com/models/seedream-5-lite.md). - You want mass drafts with no references: [FLUX Schnell](https://meetkuro.com/models/flux-schnell.md). - You need a vector file: [Recraft V4.1 SVG](https://meetkuro.com/models/recraft-v4.1-svg.md). ### Use something other than Seedream 5 when… - The picture has lettering that must be read, dense small type, or many objects in stated positions: [GPT Image 2.5 Flare](https://meetkuro.com/models/gpt-image-2.5-flare.md). - The canvas is 4:5, 5:4 or a strip such as 1:4 or 8:1: [Nano Banana 2.1](https://meetkuro.com/models/nano-banana-2.1.md). - A face, a product or an earlier frame has to be matched closely from references: [Nano Banana 2.1](https://meetkuro.com/models/nano-banana-2.1.md). - You need a vector file: [Recraft V4.1 SVG](https://meetkuro.com/models/recraft-v4.1-svg.md). - You want a big batch of rough layouts with no references: [P-Image](https://meetkuro.com/models/p-image.md). ## Both are one pick in the same composer. Switching models does not move your references or your library. --- ## About Kuro Kuro is an AI picture studio: prompt-driven images, clips, voice-overs and music, and storyboard-backed films with consistent characters across every scene.
