image 1,image 2,image 3in the order you send them - Say what stays: In edits, describe the change and add “keep everything else unchanged”
- Use
negative_promptto keep unwanted elements out instead of describing them in the prompt - Production integration: Use
webhook_urlinstead of polling for scalable applications - Error handling: Implement retry logic with exponential backoff for 503 errors
