π¨ Real-World Workflows
Interior Design: Multiple Furniture Options
Midjourney (base room) β Nano Banana (swap furniture) β Save 3 variations

Let's place some post modern style furniture in this room to furnish it, consider the layout and shape of the room, make reasonable placement of furnitures. Adds regular objects on furnitures as if someone actually lives here. make sure lighting can be casted on the furniture, keep it still as a realistic looking photograph.
E-commerce: Product Hero Images

β οΈ Common Mistakes
β Don't | β Do Instead |
---|---|
Midjourney for product photos | Use Flux/Nano Banana (accurate over beautiful) |
Qwen for final deliverables | Use Qwen for concepts, upgrade to Flux/Midjourney |
Midjourney/Flux for local edits | Use Nano Banana (built for editing) |
Nano Banana without references | Use Flux/Midjourney for pure text-to-image |

π¨ Using the Prompt Composer: Switch Models in Seconds
The Prompt Composer on the side of every article page lets you test any model instantly. Here's how to use it:
Prompt Composer UI
How to Compare Models:
Step 1: Enter Your Prompt Type your description in the text area. Be as detailed or simple as you wantβwe'll optimize it for each model.
Step 2: Select Model Click the model dropdown to choose:
- Nano Banana (for editing with uploaded images)
- GPT-4o (for text in images)
- Midjourney (for artistic beauty)
- Flux (for realistic photos)
- Seedream (for high-resolution)
- Qwen (for speed and Chinese text) You will see the generation time and the description under each option to guide you.
Step 3: Adjust Settings
- Aspect Ratio: Choose from common formats (1:1, 16:9, 9:16, etc.)
- Advanced Options: For Flux, Midjourney, GPT-4o and Seedream, you will also see secondary options, each model's options are unique features provided by the model, choose them based on your need. Next to the generation button or inside the adanced options menu, you will see the cost of the option, note that if you change the ratio for Nano Banana or use image input for Qwen, the cost will change.
Step 4: Generate and iterate Click Generate β Wait for result β Switch model β Generate again You can use the following tools on the generated result to iterate on your output.
Pro Workflow: Test the Same Prompt Across Models
- Write one good prompt
- Generate with Qwen (fast preview, 1 credit)
- If promising, generate with Flux (production quality, 3 credits)
- If needs artistic flair, try Midjourney (wow factor, 1.5-8 credits)
