Nano Banana vs Seedream 5: Which One Should You Pick?
Nano Banana and Seedream 5 are two of the best AI image models right now. This easy guide explains how they are different, which one to pick for your project, and how to test both for free with the same prompt.
Nano Banana Team
Two AI image models are getting all the attention right now: Nano Banana from Google and Seedream 5 from ByteDance. People keep asking the same question: which one is better?
Here's the honest answer: neither one wins at everything. They are good at different things. This guide explains the differences in plain words, so you can pick the right one for your project.
And you don't have to just believe us — on our comparison page you can run the same prompt on both models and see the results with your own eyes.
Meet the two fighters
Nano Banana is Google's image model family. The strongest one is Nano Banana Pro. It is famous for pictures that look like real photos — real skin, real light, real materials. It can also make very big 4K images.
Seedream 5 is made by ByteDance, the company behind TikTok. The strongest one is Seedream 5 Pro. Its superpower is writing words inside pictures. Most AI models scramble letters into alphabet soup. Seedream almost always spells them right.
Fun fact: when people ask "what is the Chinese model like Nano Banana?" — the answer is Seedream. And you can use both on this site, no Chinese account needed.
The big differences, in plain words
Words in pictures: Seedream wins
If your picture has text in it — a poster headline, a product label, a sign — Seedream 5 Pro is the safest pick. It draws small text and even text in different languages cleanly.
Real-photo look: Nano Banana wins
If you want a picture that could pass as a real photo — a portrait, a product shot with perfect light — Nano Banana Pro usually looks more real, especially skin and materials.
Big prints: Nano Banana wins
Nano Banana Pro can make 4K images. Seedream 5 Pro stops at 2K. If you're printing something big, that extra size matters.
Busy, detailed scenes: Seedream wins
A market with ten stalls, a room full of objects — Seedream 5 Pro keeps every corner sharp and detailed at 1K and 2K.
Price: about the same
On our site, Nano Banana Pro costs 8 credits for a 1K image. Seedream 5 Pro costs 10. Both are free to try — you get free credits when you sign up, no credit card needed.

We ran the test — here are real results
We gave the exact same prompt to both models, once each, at the cheapest tier. First result kept, no cherry-picking. Look for yourself.
Round 1: a poster with words
The prompt asked for a retro travel poster with the headline "VISIT KYOTO".
Nano Banana Pro:
Seedream 5 Pro:
Both spelled every word right. Nano Banana went for a flat drawing style; Seedream put the words over a real-looking photo. Different taste, both good.
Round 2: a real-photo portrait
The prompt asked for a close-up of an old fisherman in golden light.
Nano Banana Pro:
Seedream 5 Pro:
Both look like real photos. Up close, Nano Banana Pro shows more skin detail; Seedream picked a warmer, movie-like sunset.
Round 3: a busy market
The prompt asked for a farmers market with at least eight stalls and readable signs.
Nano Banana Pro:
Seedream 5 Pro:
A surprise: Nano Banana Pro kept every sign readable, while Seedream drew a bigger crowd but let a couple of signs get wobbly. The gap is smaller than the spec sheet suggests.
Round 4: an infographic with labels
The prompt asked for a smartwatch with four labeled callout lines.
Nano Banana Pro:
Seedream 5 Pro:
Nano Banana followed the four-callout plan exactly. Seedream made a cleaner, more minimal design with little icons. Both easy to read.

Common questions
Is Nano Banana or Seedream better? Neither wins everything. Text in pictures: Seedream. Real-photo look and 4K: Nano Banana. Run the same prompt on both and let your eyes decide.
Is Seedream free? The official Seedream 5 Pro lives in a Chinese app called Jimeng, which needs a Chinese account and gives very little free use. On our site you can try Seedream 5 Pro free online — free signup credits, no Jimeng account.
Can I use both models in one project? Yes, and that's often the smart move: draft cheap, then use Seedream for text-heavy images and Nano Banana Pro for photoreal shots. Your credits work on every model.
