Step-by-Step Tutorial: Creating Your First Image

Visit PiAPI's Flux Playground

Access the Flux Playground to test prompts and experiment with different models and settings interactively.

Write a Simple Text Prompt

For example, I am a marketing creative, trying to reate rapid campaign images without the photoshoot process to save on time and money. This is our prompt:

A classic glass ketchup bottle with rich, glossy red ketchup inside, featuring a bold, vintage-inspired label with bright red and white colors, set against a rustic wooden table background. The bottle is slightly tilted with ketchup dripping artistically down the side, bathed in warm natural light. The scene feels nostalgic yet fresh, with subtle reflections highlighting the smooth glass surface, perfect for a modern yet timeless condiment brand.
