Google launched Nano Banana 2 on February 26 and it immediately took the top spot on Chatbot Arena's image leaderboard. ByteDance released Seedream 5.0 Lite on the same day. We tested both. Here is what stood out.
Edit without regenerating
Upload an existing image to Nano Banana 2 and describe what you want to change. Swap the coffee mug for iced tea. Replace the succulent with a cactus. Add glasses to the person. The rest of the image stays untouched: same lighting, same composition, same background. No other image model does this natively right now.
It also does character consistency across scenes (same person, different environments), renders readable text on the first try, and supports an 8:1 panoramic format nobody else offers.

Nano Banana 2 vs Seedream 5.0 Lite: which one for what
Same day, same prompts, same settings. Nano Banana 2 won 4 out of 6 tests on photorealism and text rendering. Seedream 5.0 Lite surprised us on anime and illustration. If you use both platforms, the comparison shows exactly where each model wins.
Both are free on VicSee. See the side-by-side results ->
What Seedance 2.0 actually blocks
ByteDance suspended real face uploads on February 10. But the content filter goes further than faces. Weapons, branded characters (Iron Man, Disney princesses), and some action scenes also get flagged.
The workaround pattern: describe the scene without naming the restricted element. "A soldier shoots someone" fails. "A soldier running through a destroyed street" passes. Violence without weapons or gore generally works. We tested dozens of prompts to map the exact boundaries.
