Today, we’re putting three models head-to-head: Qwen Image 2.5.1.2, Nano Banana Pro, and ChatGPT Image 1.5.
We’re comparing real-world prompts, not fantasy art.
These are tests you can actually use — banners, infographics, thumbnails, and edits you’d create for your business.
Meet the Models
Qwen Image 2.5.1.2 was released by Alibaba on December 31, 2025.
It’s completely open-source, runs locally on your computer, and it’s free.
No limits, no subscriptions, no API costs.
Nano Banana Pro, on the other hand, is built on Gemini 3 Pro.
It’s powerful and 4K-ready, but it’s cloud-only and can get expensive fast.
Then there’s ChatGPT Image 1.5, OpenAI’s latest image update — slower than Qwen but incredibly consistent with composition and text rendering.
The First Test: Creating a Banner
The goal was simple: “Create a professional banner for the AI Profit Boardroom.”
ChatGPT Image 1.5 produced a clean, brand-ready layout — fast, functional, and crisp.
Nano Banana Pro went for detail, pulling in gradients and lighting effects, but the render took longer.
Qwen Image 2.5.1.2 finished first, creating a solid banner that looked clean but slightly lower in texture quality.
The verdict:
- ChatGPT Image 1.5 — Best overall design
- Nano Banana Pro — Best lighting and effects
- Qwen Image 2.5.1.2 — Fastest generation
Speed matters when you’re building content at scale, and Qwen crushed this round in time.
The Second Test: Infographic Design
Prompt: “Create a professional infographic on five steps to rank number one on Google.”
Qwen Image 2.5.1.2 generated a neat infographic with proper structure — keyword research, on-page SEO, link building, and more.
However, the resolution was softer.
Nano Banana Pro delivered a stunning layout with bright icons and perfect typography — exactly what you’d post on LinkedIn.
ChatGPT Image 1.5 added creativity and text variety but looked a little grainy in the background.
Winner: Nano Banana Pro.
Still, Qwen’s output was solid — and free.
For creators who want quick, usable visuals without cost, that’s a massive win.
The Third Test: Realistic Prompt Challenge
Prompt: “A man wearing a suit holding a sign that says ‘Hello World.’”
This is where Qwen Image 2.5.1.2 really surprised me.
It generated instantly — faster than both paid models.
All three produced good images, but Qwen’s realism and accuracy for a free tool stood out.
While Nano Banana Pro had more detailed lighting and ChatGPT nailed text clarity, Qwen matched both for composition at a fraction of the time.
Result: A draw.
Speed: Qwen wins again.
The Fourth Test: Image Editing
Prompt: “Make the suit rainbow-colored and make the person do a handstand.”
This round tested how well the AI could edit and follow instructions.
Only Qwen Image 2.5.1.2 understood the prompt correctly.
It gave the model four arms — hilarious, but still the only one that nailed both edits.
ChatGPT Image 1.5 and Nano Banana Pro struggled with accuracy.
Result: Qwen Image 2.5.1.2 wins this one.
Editing precision matters when creating marketing visuals — and Qwen proved it can actually follow complex commands.
The Fifth Test: YouTube Thumbnail
Prompt: “Create a thumbnail titled ‘Better Than Midjourney: Free AI Image Tool.’”
ChatGPT Image 1.5 dominated this test.
It produced the most clickable design — bold colors, clear typography, perfect spacing.
Qwen Image 2.5.1.2 came second with higher resolution but less flair.
Nano Banana Pro finished last because its textures looked grainy.
Result:
- ChatGPT Image 1.5 — 1st place
- Qwen Image 2.5.1.2 — 2nd place
- Nano Banana Pro — 3rd place
Overall Results
After five rounds:
- ChatGPT Image 1.5 won twice
- Nano Banana Pro won once
- Qwen Image 2.5.1.2 won once and drew once
That’s a major result for a free, open-source tool released only days ago.
Qwen didn’t just hold its own — it beat paid models in multiple real-world tests.
Why Qwen Image 2.5.1.2 Matters
Speed. Freedom. Accuracy.
It’s the fastest model I’ve tested for generating usable business images.
No logins. No cloud wait times. No monthly bills.
You can install it locally and start creating instantly.
It’s open source, so developers can improve it constantly — meaning the next update could outperform everything.
And when you pair Qwen with tools like Gemini or ChatGPT, you unlock full creative control: generate, edit, and refine in one system.
