Model Switching Guide

This guide answers three direct questions:

• how to switch between models in Flux AI
• which model to choose for a given image goal
• what kind of outputs each model usually handles well

How to switch models

Use the model selector directly in the prompt box:

1. Choose Text-to-Image if you are starting from a blank prompt.
2. Choose Image-to-Image if you already have a base image and want to preserve composition while refining.
3. Open the model dropdown.
4. Switch models based on task intent, not just model familiarity.
