How to use ModelPixLab.
三步出图，外加写好提示词的小技巧。
No installs, no Photoshop. Everything happens on the model pages: describe what you want, pick a model, generate, download. This page walks through each step and shows how to write prompts that get better results.
不用装软件：打开模型页，描述、选模型、生成、下载。这页把每一步和提示词技巧都讲清楚。
Getting started
Three steps to your image
STEP 1
Describe your image
Open a model page and type what you want to see in the prompt box. Plain sentences work: "a cozy cabin in snowy mountains at dusk". Not sure where to start? Tap one of the example chips to fill the box, then edit it.
STEP 2
Pick model & settings
Each page is one model. Choose the image size (square, landscape or portrait) and, where offered, the style or mode. Editing a photo? Switch to Edit mode and upload your picture first.
STEP 3
Generate & download
Press Generate. Most images take seconds. Happy with it? Download up to 4K. Want another take? Adjust one detail in the prompt and generate again — small changes, better odds.
Prompt tips
Write prompts that work
Four habits that make the biggest difference. 四个最有用的小习惯。
02
Add a style word
Finish with the look you want: photo, anime, illustration, 3D render, watercolor. One style word anchors the whole image.
03
Put text in quotes
Words inside the image go in quotation marks: a neon sign that says "OPEN". Short text works best — a few words, spelled exactly.
04
Change one thing at a time
Regenerating with the same prompt gives variations. To fix a result, change one detail per round instead of rewriting everything.
Editing photos
Edit by describing the change
UPLOAD
Add your photo
On the Nano Banana 2 page, switch to Edit mode and upload the photo you want to change.
DESCRIBE
Say what changes
"Make it golden hour", "remove the people in the back", "turn this into a watercolor painting". Faces and details stay consistent.
REFINE
Go round by round
Each edit builds on the last. Fix one thing per message and the result stays under your control.
