Demo summary

The user demonstrates generating a 'fantasy mage' portrait using Flux 2 Klein 4B Fast, 4B, and 9B models on NightCafe, comparing their speed, lighting, and anatomical accuracy.

Step-by-step

Enter a prompt for your fantasy character portrait
Select the Flux 2 Klein 4B Fast, 4B, or 9B model
Toggle Prompt Magic on if desired
Choose an aspect ratio such as Square or 3:4 Portrait
Select the number of images to generate
Click Create to generate the images

Options

Switch between 4B Fast, 4B, and 9B models to compare speed and detail
Toggle between Square and Portrait aspect ratios
Adjust the number of images per generation

Watch out for

Generating multiple images or using non-base settings costs additional credits
The 4B Fast model may produce slightly grainier results with more background noise compared to higher tiers
Lower-tier models like the 4B may struggle with anatomical accuracy, such as generating extra fingers

Tips

Use the NightCafe Pro subscription to access certain models for free
Use the 9B model if you need superior lighting, detail, and better hand anatomy
The 4B Fast model is ideal if speed is the priority, as it can generate in just a few seconds

Highlights

“I couldn't even finish my thought before it was done generating.”
