doubao vs nanobanana

Summary: We tested the trending “Bunny Ears Convex Mirror Selfie” prompt on Doubao (local LLM) vs. Nanobanana Pro. The difference in hand anatomy and physics is… shocking.
摘要: 最近“兔耳朵+凸透镜自拍”很火。我们用同样的题材对比了国产大模型“豆包”与 Nanobanana Pro 的生成效果。结果显示,如果不使用优化后的指令,你的自拍可能会变成“恐怖片”。

📉 The “Horror” Show: Doubao’s Attempt (豆包的翻车现场)

We love Doubao for its Chinese semantic understanding, but when it comes to complex hand anatomy combined with lens distortion (fisheye/convex mirror), things get weird fast.
我们很喜欢豆包的中文理解能力,但在处理复杂手部结构叠加广角畸变(鱼眼/凸透镜)时,它彻底“晕”了。

Here are the raw results from Doubao (No Nanobanana Optimization):
(以下为豆包直出效果,未经 Nanobanana 优化)

❌ Fail Case 1: The “Claw” Hand (鸡爪手)

doubao Fail Case 1
  • The Issue: Look at the hand holding the phone. It looks more like a chicken claw than a human hand. The fingers are impossibly long and twisted.
  • 问题: 看看这只拿手机的手,手指像被拉面师傅拉过一样,完全违反人体工学。

❌ Fail Case 2: The “Melting” Phone (手机液化)

doubao Fail Case 2
  • The Issue: The phone seems to be merging into the palm. Physics logic is broken.
  • 问题: 手机仿佛融化进了肉里,物理逻辑完全崩坏。

The Solution: Nanobanana Pro Logic (正确打开方式)

Why does this happen? Because standard models confuse “mirror distortion” with “object distortion”. They distort the phone and hand instead of just the reflection.
为什么会这样?因为普通模型分不清“镜面畸变”和“物体畸变”。它们把手和手机也给扭曲了,而不是只扭曲镜子里的倒影。

Nanobanana Pro solves this by enforcing:

  1. Anatomy Lock: Forcing standard hand structure before applying lens effects.
  2. Ray Tracing Logic: Correctly calculating light reflection on the convex surface.
  3. Texture Quality: 4K skin texture vs. “plastic” skin.

🏆 The Result (Nanobanana Pro)

(Our optimized prompt generates this consistently)

  • Perfect Hands: Fingers grasp the phone naturally.
  • Real Reflection: The distortion only affects the reflection edges, keeping the center face clear.
  • Atmosphere: City lights and bunny ears blend perfectly in a cinematic night vibe.
